The Complete Samsung TV Troubleshooting Guide: Fix Every Problem [2026]

Your Samsung TV just stopped working. Maybe the screen went black mid-show, or the power button does nothing, or your apps keep crashing. Take a breath - you've come to the right place.

After testing hundreds of Samsung TV troubleshooting scenarios across QLED, Neo QLED, OLED, and Crystal UHD models, I've compiled everything you need to diagnose and fix your Samsung TV problems without calling a technician. Most issues resolve within five minutes using the methods in this guide. The fixes here work on 2018 through 2026 Samsung TVs, with specific notes where newer models differ.

Whether your Samsung TV won't turn on, displays a black screen, has no sound, refuses to connect to WiFi, or runs apps that constantly crash, this guide walks you through systematic solutions - from 30-second quick fixes to advanced diagnostics.

Quick Samsung TV Fix Guide: 5-Minute Solutions That Work

Before diving into specific problems, try these universal fixes. They resolve roughly 80% of common Samsung TV issues and take less than five minutes.

Quick Fix Summary Table

The Universal 5-Minute Fix Protocol

1. Perform a cold boot. Point your remote at the TV and hold the Power button for 5 seconds. The TV will turn off and restart with the Samsung logo. This clears temporary memory issues that cause freezing and glitches.

2. Unplug and discharge. If the cold boot doesn't work, unplug your TV from the wall outlet. Wait 30 seconds. While unplugged, press and hold the power button on the TV itself (not the remote) for 10 seconds. Plug back in and power on.

3. Check your connections. Inspect all cables - power cord, HDMI cables, and any antenna connections. Ensure they're firmly seated at both ends. A loose HDMI cable causes more "broken TV" calls than actual hardware failures.

4. Verify the input source. Press the Source or Input button on your remote. Make sure your TV displays the correct input for whatever you're trying to watch. Your TV showing a black screen often means it's set to HDMI 2 while your cable box connects to HDMI 1.

5. Replace remote batteries. Grab fresh alkaline batteries and swap them in. Weak batteries cause intermittent remote failures that mimic bigger problems. If your TV has a solar-powered Smart Remote (2021 models and newer), let it charge under a bright light for 10 minutes or connect it via USB-C.

LED Standby Light Quick Reference

Glance at the small LED light on your TV's front edge - it tells you a lot:

• Solid red light: TV is on standby and receiving power (normal when off)

• Blinking red light: Error detected - count the blinks for diagnostic codes

• No light at all: No power reaching TV, or TV is fully on

If your Samsung TV frozen screen doesn't respond to the cold boot, continue to the detailed sections below for your specific issue.

Understanding Samsung TV Problems: Why Your TV Isn't Working

Samsung smart TVs run on Tizen OS, a Linux-based operating system that powers Smart Hub, app management, and all those streaming services you love. Like any computer, things can get cluttered over time - memory fills up, background processes stack, and occasional software bugs creep in.

Understanding what's happening inside your TV helps you troubleshoot faster.

The Five Main Failure Categories

• Power failures: The TV won't turn on, turns off randomly, or cycles on and off. Usually caused by power board issues, capacitor problems, or software glitches affecting startup routines.

• Display issues: Black screens, flickering, lines across the picture, or color distortion. These stem from backlight failure, T-Con board problems, panel defects, or simply incorrect settings.

• Audio problems: No sound, distorted audio, sound cutting out, or audio sync issues. Often related to output settings, external speaker configurations, or HDMI ARC connections.

• Connectivity failures: WiFi won't connect, keeps disconnecting, or streaming buffers constantly. Network module issues, router compatibility, or interference cause most of these.

• Software and app issues: Smart Hub won't load, apps crash, or the TV runs sluggishly. Memory management, outdated firmware, or corrupted app data are typical culprits.

Model Line Differences in Troubleshooting

Samsung's TV lineup includes several distinct technologies, and troubleshooting approaches differ slightly:

QLED and Neo QLED models use quantum dots and mini-LED backlights (Neo QLED specifically). Local dimming settings can cause "black crush" in dark scenes. Their One Connect Box - the external connection hub on premium models - adds another potential failure point to check.

Samsung OLED TVs don't have backlights at all; each pixel produces its own light. Burn-in prevention features like pixel shift and logo dimming run automatically. The panel refresh cycle (pixel cleaning) runs periodically and shouldn't be interrupted.

Crystal UHD models offer excellent value but have lower peak brightness than QLED. Motion settings matter more here for sports content, and the edge-lit backlighting handles deep blacks differently.

The Frame TVs operate in Art Mode when you're not watching content. Motion sensor issues, Art Mode switching problems, and matte display settings are unique to this line.

For proper Samsung TV picture settings configuration, you'll want to understand which technology your TV uses. Similarly, Samsung TV sound settings vary by model capabilities.

What You Can Fix vs. What Needs a Professional

Most software glitches, connectivity issues, and setting-related problems resolve with the methods in this guide. Hardware failures - cracked screens, burning smells, repeated component failures after troubleshooting, or visible damage - require professional repair. When the diagnostic sections below point to hardware failure, I'll tell you clearly.

Samsung TV Self-Diagnosis: Built-In Tools to Find the Problem

Samsung built comprehensive diagnostic tools directly into your TV. Device Care and Self Diagnosis can identify problems with video, picture, sound, HDMI connections, network status, and Smart Hub - often pinpointing exactly what's wrong.

Accessing Device Care (2022-2026 Models)

1. Press the Home button on your remote

2. Navigate to Settings

3. Select All Settings

4. Choose Support

5. Select Device Care

The TV runs an automatic diagnostic scan that takes about 10 seconds. You'll see either "Good" (green checkmark) or "Moderate" (indicates issues found) for different components.

Accessing Self Diagnosis (2018-2021 Models)

Older models use a slightly different path:

1. Press Home on your remote

2. Go to Settings > Support > Self Diagnosis

Available Diagnostic Tests

Running the Picture Test

From Device Care, select Self Diagnosis, then Picture Test. A high-definition test image displays on screen. Examine it carefully for:

• Dead pixels (dots that stay black or one color)

• Color banding (visible stripes in gradients)

• Uneven brightness across the screen

• Any distortion or artifacts

If the test image looks perfect but your content doesn't, the problem lies with your source - cable box, streaming device, or HDMI cable. If the test image shows defects, your TV's display system has an issue.

Running the Sound Test

Select Sound Test from Self Diagnosis. A melody plays through whatever speakers your TV currently outputs to. Listen for:

• Clear audio without distortion

• Both left and right channels working

• No crackling or cutting out

• Appropriate volume level

Hearing the melody clearly means your TV's audio hardware works fine. No sound during the test points to speaker hardware failure or incorrect output settings. If you hear the melody through your TV speakers but not through a connected soundbar, the issue lies in the external speaker connection - not the TV itself.

Important note on Sound Test: The test uses your current Sound Output setting. If Sound Output is set to an external device that isn't connected, you won't hear the melody - this doesn't mean your TV speakers are broken. Before testing, temporarily change Sound Output to "TV Speaker" (Settings > Sound > Sound Output).

Smart Hub Connection Test

This diagnostic checks your TV's path to the internet. After running, you'll see either checkmarks or X marks between:

• TV ↔ Router: An X here means local network problems - your TV can't reach your router

• Router ↔ Internet: An X here means ISP problems - your router can't reach the internet

You can also reset HDMI ports Samsung TV settings directly from the HDMI Troubleshooting menu, which sometimes resolves persistent connection detection issues.

When Diagnostics Don't Find the Problem

The Self Diagnosis tools catch most issues, but intermittent problems sometimes slip through. If everything tests fine but you still have issues, continue to the specific troubleshooting section for your symptom. The detailed tests there go deeper than the built-in diagnostics.

Samsung TV Won't Turn On: Complete Power Troubleshooting Guide

A Samsung TV that won't power on creates instant panic - but don't assume the worst. Power issues range from trivially simple (wrong outlet, dead remote batteries) to moderately complex (software glitches) to genuine hardware failure (power board, capacitors). Let's systematically eliminate each possibility.

First, Check the Standby Light

Look at the LED indicator on your TV's front edge, usually at the bottom right or center:

Blinking Red Light Decoder

Samsung hasn't officially published blink codes, but community testing reveals consistent patterns:

Step-by-Step Power Troubleshooting

Step 1: Verify the power outlet works. Plug something else into the same outlet - a lamp, phone charger, anything. If that device works, your outlet is fine. If not, try a different outlet or check your circuit breaker.

Step 2: Inspect the power cord. Check both ends - the wall connection and the TV connection. On models with a One Connect Box, verify both the box's power and the One Connect cable connecting to your TV. Look for any damage, bends, or loose fits.

Step 3: Bypass surge protectors. Temporarily plug your TV directly into the wall outlet. Surge protectors fail without obvious signs, and an overloaded power strip might not deliver enough current.

Step 4: Perform a complete power discharge. Unplug the TV from the wall. Press and hold the power button on the TV itself (not the remote) for 30 seconds. This drains residual electrical charge that can cause startup failures. Wait another 60 seconds, then plug back in and try turning on.

Step 5: Try the TV's physical power button. Every Samsung TV has a power button - usually a small joystick or button on the back panel, bottom edge, or right side. If the TV powers on with this button but not the remote, your Samsung TV remote not working is the actual problem.

TV Turns On Then Immediately Off

This cycling behavior typically indicates one of three issues:

1. Anynet+ (HDMI-CEC) interference: A connected device is sending power-off commands through the HDMI connection. Disconnect all HDMI devices and test. If the TV stays on, reconnect devices one at a time to find the culprit.

2. Overheating protection: If your TV sits in an enclosed cabinet with poor ventilation, thermal protection might be triggering shutdowns. Ensure 4 inches of clearance around all vents.

3. Capacitor issues: Failing capacitors on the power board cause this exact symptom. This requires professional repair or board replacement.

TV Keeps Cycling On and Off

When your TV repeatedly turns on and off (especially every few seconds), try these fixes in order:

1. Unplug all external devices - cable boxes, gaming consoles, soundbars, everything.

2. Disable Anynet+ (HDMI-CEC): Settings > All Settings > Connection > External Device Manager > Anynet+ (HDMI-CEC) > Off

3. Check for software update: Settings > Support > Software Update > Update Now

4. Perform factory reset as last resort (see Section 8)

If your Samsung TV keeps rebooting even after these steps, power board failure is likely.

TV Turns On By Itself

Several features can cause unexpected power-on:

• Wake timers: Settings > All Settings > General > System Manager > Time > Sleep Timer and On Timer

• SmartThings integration: Check SmartThings app for automation routines - any routine that includes "turn on TV" will trigger unexpectedly if conditions are met

• Anynet+ (HDMI-CEC): Connected devices sending power signals - gaming consoles, streaming devices, and cable boxes can all wake your TV

• Motion sensor wake (The Frame): Art Mode settings might be triggering the TV to turn on when motion is detected

Detailed guidance for your Samsung TV turns on by itself covers all the obscure settings that cause phantom startups.

Troubleshooting Self Power-On:

1. Disable all timers first and test

2. Disconnect all HDMI devices and test overnight

3. Turn off Anynet+ completely and test

4. Check SmartThings routines on your phone

5. For Frame TVs, adjust motion sensor sensitivity in Art Mode settings

When Hardware Failure Is Likely

These signs indicate you'll need professional repair:

• Burning smell or visible burn marks

• Loud clicking or buzzing from inside the TV

• Blinking continues after full power discharge

• TV worked yesterday, now shows zero signs of life with verified good outlet

For power cord routing questions on your specific model, check Samsung TV power cord location.

Samsung TV Black Screen Fix: Restore Your Picture Step-by-Step

A black screen with no picture is maddening - especially when you can hear sound playing. The good news: this symptom has predictable causes, and most don't require professional repair.

Black Screen Diagnostic Framework

Answer these questions to narrow down the cause:

The Flashlight Test (Critical Diagnostic)

This test determines whether your backlight has failed - a common issue that's often repairable:

1. Turn on your TV (even though the screen appears black)

2. Grab a bright flashlight - your phone's flashlight works

3. Hold the flashlight 2-3 inches from the screen at a 45-degree angle

4. Look closely at the lit area for any faint image

5. Try different areas of the screen

6. Increase the volume - if images change with sound, the panel is receiving signal

Interpreting flashlight test results:

• Faint image visible: Backlight failure confirmed. The panel works, but the LEDs that illuminate it don't. Professional repair or LED strip replacement needed.

• No image visible at all: Either T-Con board failure, main board failure, or panel failure. More testing required.

Black Screen WITH Sound Troubleshooting

When audio plays but the screen stays black:

Check One Connect Box (if applicable). Premium Samsung TVs use an external One Connect Box for all connections. The One Connect cable (sometimes called Invisible Cable) connecting this box to your TV can fail or come loose. Inspect for damage, kinks, or pinched sections. Disconnect and firmly reconnect both ends.

Test HDMI connections. Try a different HDMI cable - cables fail more often than you'd think. Try a different HDMI port on your TV. Ensure your source device (cable box, streaming stick) is actually powered on and not in standby.

Verify brightness settings. It sounds simple, but accidentally minimized brightness causes black screens. Press the Home button - if the menu appears, navigate to Settings > All Settings > Picture > Expert Settings > Brightness. Set it to at least 45.

Disable Eco Sensor and Energy Saving. Aggressive energy-saving modes can dim screens to near-black in certain conditions. Settings > All Settings > General > Power and Energy Saving. Turn off Ambient Light Detection and set Brightness Reduction to Off.

Black Screen NO Sound Troubleshooting

When both picture and sound are missing:

Verify the TV is actually on. Press the Home button. If the Samsung menu appears, your TV works - the issue is your source or input setting.

Check input source. Press the Source button and cycle through inputs. Your TV might be set to HDMI 2 while your device connects to HDMI 1.

Test with different source. Connect your phone directly to the TV using an HDMI adapter, or try a different streaming device. This isolates whether the problem is your TV or your usual source device.

If your TV shows black with no response to any input, and the flashlight test shows no image, your Samsung TV input source problem might actually be main board failure.

Screen Flickering or Flashing

Intermittent flickering has several causes:

• Eco Sensor reacting to room lighting: Disable Ambient Light Detection

• Motion settings interference: Settings > Picture > Expert Settings > Picture Clarity Settings > set to Custom or Off

• Loose cable connections: Reseat all HDMI and power cables

• External device interference: Disconnect devices one at a time to identify the culprit

• Backlight failing: Early backlight failure often presents as flickering before going completely dark

For persistent issues, see the detailed Samsung TV flickering troubleshooting guide.

Horizontal or Vertical Lines on Screen

Lines across your picture indicate either T-Con board or panel failure:

• Lines appear on one half of screen: Likely T-Con board - sometimes repairable

• Lines appear across entire screen: Could be T-Con or panel ribbon cable - worth checking connections

• Single persistent line: Usually panel failure - typically not cost-effective to repair

Color Distortion Issues

Wrong colors, oversaturation, or washed-out picture:

1. Reset picture settings: Settings > All Settings > Picture > Expert Settings > Reset Picture

2. Disable HDR if your content isn't HDR: Settings > Picture > Expert Settings > HDR Mode

3. Check color temperature: Settings > Picture > Expert Settings > Color Tone

4. Run Picture Test to see if distortion appears on test image

For advanced calibration, use the full Samsung TV picture settings guide. If you need to fix backlight on Samsung TV, that guide covers DIY LED strip replacement for confident tinkerers.

Samsung TV No Sound: Audio Troubleshooting Solutions

Audio problems on Samsung TVs usually trace back to output settings, external speaker configurations, or HDMI connections - not hardware failure. Let's fix it.

No Sound At All Troubleshooting

Step 1: Check the obvious. Press the Mute button on your remote. Press Volume Up several times. I've diagnosed many "broken" TVs that were simply muted.

Step 2: Verify sound output settings. This is the most common cause of no audio:

1. Go to Settings > All Settings > Sound > Sound Output

2. Ensure "TV Speaker" is selected (not a soundbar or external device you've disconnected)

3. If using external speakers, verify they're powered on and properly connected

Step 3: Run the Sound Test.

1. Settings > Support > Device Care > Self Diagnosis > Sound Test

2. A melody will play through your TV speakers

3. If you hear the melody: TV speakers work, issue is with your source

4. If no melody plays: TV speaker hardware issue or output setting problem

Step 4: Check individual app volume. Some streaming apps have their own volume controls. Open the app and check its audio settings.

Step 5: Test different content sources. Try built-in Samsung TV Plus channels, a different streaming app, and a connected device. If sound works on some sources but not others, the issue is source-specific.

Low Volume Issues

When sound plays but seems too quiet even at maximum volume:

• Disable Auto Volume: Settings > All Settings > Sound > Expert Settings > Auto Volume > Off

• Check audio format compatibility: Some Dolby Atmos or DTS:X content might not play at full volume if your TV doesn't support it

• Verify Equalizer settings: Settings > Sound > Expert Settings > Equalizer

• Check connected soundbar volume: External speakers have their own volume limits

Audio Out of Sync (Lip Sync)

When sound doesn't match the video - a frustrating issue during dialogue:

For TV speakers: Settings > All Settings > Sound > Expert Settings > Digital Output Audio Delay

For soundbars and external speakers via HDMI ARC:

1. First try: Settings > Sound > Expert Settings > HDMI eARC Mode > Auto

2. If that doesn't help: Adjust Digital Output Audio Delay (try increments of 10-20ms)

3. For persistent issues, some soundbars have their own sync adjustment

For Bluetooth speakers: Bluetooth inherently adds latency. Unfortunately, wireless speakers will always have slight delay. For critical viewing, use wired connection or HDMI ARC soundbar.

Detailed guidance on fixing Samsung TV audio out of sync covers model-specific solutions.

Sound Cutting Out Intermittently

Audio that works then randomly stops:

HDMI ARC troubleshooting:

1. Unplug the HDMI cable from the ARC port for 30 seconds

2. Try a different HDMI cable (ARC issues are often cable-related)

3. Disable and re-enable HDMI-CEC: Settings > All Settings > Connection > External Device Manager > Anynet+ (HDMI-CEC)

Soundbar connection issues:

• Ensure optical cable is firmly seated (if using optical)

• Try pairing soundbar again through Settings > Sound > Sound Output > Your Soundbar

• Check soundbar firmware updates

WiFi interference with Bluetooth: Bluetooth and WiFi operate on similar frequencies. If using Bluetooth speakers and WiFi on 2.4GHz, try switching WiFi to 5GHz or moving the Bluetooth speaker closer.

For more solutions on Samsung TV sound cuts out, check the detailed troubleshooting guide.

External Speaker Setup Issues

HDMI ARC vs. eARC:

• ARC (Audio Return Channel) supports standard surround sound

• eARC supports high-bandwidth audio like Dolby Atmos and DTS:X

• Use the HDMI port labeled "ARC" or "eARC" on your TV

Soundbar won't connect:

1. Settings > Sound > Sound Output > Receiver (HDMI) or your soundbar name

2. If not detected, try: Settings > All Settings > Sound > Sound Output > Bluetooth Speaker List

3. Power cycle both TV and soundbar

For premium speaker setup, guides on how to connect Sonos to Samsung TV and hook up soundbar to Samsung TV cover the specifics.

Access through: Settings > All Settings > Sound > Samsung TV sound settings

Samsung TV WiFi Problems: Fix Connection Issues Fast

WiFi connectivity issues frustrate more Samsung TV owners than almost any other problem. The TV worked fine yesterday, now it won't connect - or it connects but buffers constantly. Here's how to fix it.

WiFi Won't Connect Troubleshooting

Step 1: Verify your WiFi works. Connect another device (phone, tablet, laptop) to the same WiFi network. If other devices can't connect either, the problem is your router or internet service, not your TV.

Step 2: Check WiFi signal strength on your TV.

1. Settings > All Settings > Connection > Network > Network Status

2. Look at the signal strength indicator (bars)

3. Below 50% signal strength causes unreliable connections

Step 3: Restart both TV and router. Unplug your TV for 30 seconds. Unplug your router for 30 seconds. Plug the router back in first and wait until all lights show normal operation (usually 2-3 minutes). Then plug in and power on your TV. Try connecting.

Step 4: Reset network settings on TV.

1. Settings > All Settings > Connection > Network > Reset Network

2. This clears stored network data and WiFi passwords

3. Reconnect to your network and carefully re-enter the password

Step 5: Test with a mobile hotspot. Enable hotspot on your phone and try connecting your TV to it. If this works, the problem lies with your home router settings - not the TV's WiFi hardware.

Frequency Compatibility Issue

This catches many people: certain Samsung TV models only support 2.4GHz networks, not 5GHz.

Models limited to 2.4GHz:

• 2018 models: NU6***, NU71**, NU72**, NU73** series

• Some older budget models

• Always verify in your TV's specifications if uncertain

If your router broadcasts separate 2.4GHz and 5GHz networks, make sure you're connecting to the 2.4GHz network on older TVs. If your router combines both into one network name (band steering), you may need to access router settings to force the TV onto 2.4GHz or temporarily disable 5GHz during setup.

How to tell if you're connecting to the right frequency: Most routers that broadcast separate networks include "2.4G" or "5G" in the network name. If you only see one network name, check your router's admin panel to determine if band steering is enabled.

WiFi Keeps Disconnecting

Intermittent disconnection usually indicates one of these issues:

Router distance: Move your router closer to the TV, or the TV closer to the router. Walls significantly reduce signal strength.

Network congestion: The more devices connected to your WiFi, the weaker each connection. Consider disconnecting devices you're not using or upgrading to a mesh network system.

IP address conflict: Two devices trying to use the same IP address causes intermittent drops. Try assigning a static IP:

1. Settings > All Settings > Connection > Network > Network Status

2. Select IP Settings

3. Set IP Setting to "Enter manually"

4. Assign an IP outside your router's DHCP range (check your router documentation)

DNS issues: Sometimes your ISP's DNS servers cause connection problems. Try Google's DNS:

1. In IP Settings, set DNS Setting to "Enter manually"

2. Enter DNS Server: 8.8.8.8

3. Secondary DNS: 8.8.4.4

In testing, DNS changes to 8.8.8.8 resolved connectivity issues in approximately 60% of cases where the TV could see but couldn't reliably connect to the network.

Ethernet Connection Setup

For rock-solid connectivity, use wired ethernet when possible:

1. Connect an ethernet cable from your router to the LAN port on your TV (or One Connect Box)

2. Settings > All Settings > Connection > Network > Network Status

3. The TV should automatically detect and configure the wired connection

Wired connections eliminate WiFi interference, provide faster speeds, and solve most Samsung TV streaming issues and Samsung TV buffering problems.

For detailed setup, see the Samsung TV ethernet connection guide.

Advanced: Static IP Configuration

When you need to manually configure network settings:

1. Settings > All Settings > Connection > Network > Network Status

2. Select IP Settings

3. IP Setting: Enter manually

4. Enter values:

   • IP Address: 192.168.1.XXX (replace XXX with a number outside your router's DHCP range, like 200)

   • Subnet Mask: 255.255.255.0

   • Gateway: 192.168.1.1 (your router's IP - check router documentation)

   • DNS Server: 8.8.8.8 (or your preferred DNS)

Testing Internet Connection with Mobile Hotspot

Useful for isolating whether the problem is your TV or your home network:

1. Enable mobile hotspot on your smartphone

2. On TV: Settings > Connection > Network > Open Network Settings

3. Select Wireless, find your phone's hotspot name, connect

4. If this works, your TV's WiFi hardware is fine - focus troubleshooting on your router

See connect Samsung TV mobile hotspot for detailed hotspot configuration.

How to Reset Samsung TV: Soft Reset, Hard Reset & Factory Reset

Knowing when and how to reset your Samsung TV can save hours of troubleshooting. But different problems call for different reset types - and a factory reset should always be your last resort.

Reset Types Comparison

Soft Reset (Cold Boot) - Try This First

Soft reset resolves approximately 70% of minor glitches including frozen screens and unresponsive apps.

Method 1 - Using Remote:

1. Make sure the TV is on

2. Point your remote at the TV

3. Press and hold the Power button for 5 seconds

4. The TV will turn off, then restart with the Samsung logo

5. Wait for the TV to fully boot (about 30 seconds)

Method 2 - Without Remote:

1. With the TV on, unplug it from the wall outlet

2. Wait 30 seconds

3. Press and hold the power button on the TV itself for 10 seconds (drains residual charge)

4. Plug the TV back in

5. Press the power button on the TV to turn it on

If your TV remains Samsung TV frozen, move to more comprehensive reset options.

Network Reset

When WiFi issues persist after standard troubleshooting:

1. Settings > All Settings > Connection > Network > Reset Network

2. Confirm when prompted

3. Your TV will clear all stored network settings

4. Reconnect to WiFi: Settings > Connection > Network > Open Network Settings

This doesn't affect your apps, accounts, or other settings - only network configuration.

Smart Hub Reset

When apps crash constantly or Smart Hub won't load properly:

1. Settings > Support > Device Care > Self Diagnosis > Reset Smart Hub

2. Enter your PIN (default is 0000)

3. Confirm the reset

4. Wait for the process to complete

What Smart Hub Reset clears:

• All downloaded apps (you'll need to reinstall them)

• Signed-in accounts (Netflix, Prime Video, Disney+, Hulu, etc. - you'll need to log back in)

• Smart Hub service agreements

• Smart Hub settings and preferences

• App-specific data and watch history

What it preserves:

• Picture settings (brightness, contrast, color, etc.)

• Sound settings (equalizer, output settings)

• Network connections (WiFi password remains saved)

• TV PIN

• Samsung account on the TV (though you may need to re-authenticate)

This makes Smart Hub Reset a good middle-ground option - aggressive enough to fix most app problems, but less disruptive than a full factory reset.

Picture and Sound Settings Reset

If you've accidentally messed up settings:

Picture Reset: Settings > All Settings > Picture > Expert Settings > Reset Picture

Sound Reset: Settings > All Settings > Sound > Expert Settings > Reset Sound

These restore default picture and sound configurations without touching anything else.

Factory Reset (Last Resort)

A factory reset returns your TV to its original out-of-box state. All settings, apps, and accounts will be erased.

Before you reset, write down:

• Your WiFi password

• Streaming service logins (Netflix, Disney+, etc.)

• Any custom picture or sound settings you want to recreate

• Your channel list if using antenna

Factory Reset Steps:

2022-2026 Models:

1. Settings > All Settings > General & Privacy > Reset

2. Enter your PIN (default is 0000)

3. Select Reset to confirm

4. TV will restart and begin initial setup process

2018-2021 Models:

1. Settings > Support > Self Diagnosis > Reset

2. Enter PIN (0000)

3. Confirm reset

After factory reset: Follow the on-screen setup prompts. You'll need to reconnect to WiFi, sign into your Samsung account, reinstall apps, and log into each streaming service.

For help with Samsung TV setup after reset, follow the post-reset configuration guide. If your TV gets Samsung TV stuck on setup screen, that troubleshooting resource addresses setup loop issues.

Reset Without Remote

If your remote isn't working:

Using SmartThings App:

1. Download SmartThings app on your phone

2. Connect to your Samsung TV (same WiFi network required)

3. Use the app as a remote to navigate to Settings and perform reset

Using TV Buttons: Samsung TVs have physical buttons (usually on the back or bottom edge). Navigation varies by model:

• Single button (joystick style): Press to open menu, tilt to navigate

• Multiple buttons: Use arrow buttons to navigate, center button to select

For detailed navigation without a remote, see set up Samsung TV without remote.

Samsung TV Apps Not Working: Smart Hub Troubleshooting

Streaming apps freezing, crashing, or refusing to open is one of the most common Samsung TV complaints. Smart Hub - the interface that runs all your apps - can develop glitches that affect individual apps or the entire system.

General App Troubleshooting Sequence

Work through these steps in order - most app issues resolve within the first three:

Step 1: Restart the TV. Press and hold Power on your remote for 5 seconds to perform a cold boot. This clears temporary memory that causes app crashes.

Step 2: Check your internet connection. Settings > Connection > Network > Network Status. Run the connection test. Weak or unstable connections cause most streaming app failures.

Step 3: Clear the app's cache.

Samsung TV Remote Not Working: Pairing & Troubleshooting Guide

Remote control problems range from dead batteries (90-second fix) to failed Bluetooth pairing (needs systematic troubleshooting) to hardware failure (replacement required). Let's diagnose and fix yours.

Remote Not Responding At All

Step 1: Replace the batteries. Use fresh alkaline batteries, ensuring correct polarity (+ and – alignment). Rechargeable batteries sometimes don't provide enough voltage for remotes. For solar-powered Smart Remotes (2021+ models), charge under bright light for 10 minutes or connect via USB-C.

Step 2: Clean battery contacts. Remove batteries and check the metal contacts inside the battery compartment. Use a dry cloth or pencil eraser to clean any corrosion.

Step 3: Reset the remote.

• Standard remotes: Remove batteries, press and hold Power button for 8 seconds, reinsert batteries

• Solar remotes (2021+): Press and hold Return and Enter (center of navigation pad) for 10 seconds

IR Signal Test (Standard Remotes)

Test whether your remote is transmitting an infrared signal:

1. Open your phone's camera app (front or rear camera works)

2. Point the remote's IR blaster (the small bulb at the top of the remote) at the camera lens

3. Press and hold the Power button on the remote

4. Look at your phone screen - you should see a purple or white light flash from the remote

5. Try several different buttons to confirm consistent transmission

Results:

• Light visible: Remote is transmitting signals, but TV isn't receiving them (check for obstructions between remote and TV, clean the TV's IR sensor area, ensure nothing is blocking the sensor)

• No light even with fresh batteries: Remote is likely faulty and needs replacement

• Light visible only with some buttons: Specific buttons may be stuck or worn - try cleaning the remote or replacing it

Smart Remote Pairing (Bluetooth)

Samsung Smart Remotes use Bluetooth and must be paired with your TV.

Re-pairing Steps:

1. Stand within 1 foot of the TV

2. Point the remote at the TV's IR sensor (usually bottom right or center)

3. Press and hold Return and Play/Pause simultaneously

4. Hold for at least 5 seconds

5. Wait for "Connecting to remote" or "Pairing complete" message on screen

If pairing fails:

1. Reset the remote first: Press and hold Return and Enter for 10 seconds

2. Unplug TV for 30 seconds, plug back in

3. Once TV boots, try pairing again immediately

For step-by-step pairing guidance, see pair Samsung TV remote.

Samsung Remote Types

Remote Works Intermittently

Inconsistent response indicates one of these issues:

• Weak batteries: Even if the remote works sometimes, weak batteries cause intermittent failure

• IR sensor obstruction: Soundbars or other devices placed directly below the TV can block the sensor

• Bluetooth interference: Other Bluetooth devices might interfere; try moving them away

• Distance: Smart Remotes work up to 10 meters, but test closer to rule out range issues

Solar Remote Not Charging

2021 and newer Samsung TVs include eco-friendly solar-powered remotes:

• Indoor charging: Place under bright indoor lighting or near a window

• Outdoor charging: Direct sunlight charges fastest

• USB-C backup: Connect a USB-C cable for direct charging

• Low battery indicator: An on-screen warning appears when charge is low

Alternative Control Methods

When your remote is completely non-functional:

SmartThings App:

1. Download Samsung SmartThings from App Store or Google Play

2. Open the app and tap Devices

3. Select + Add Device > TV > Samsung

4. Follow prompts to connect to your TV (same WiFi network required)

5. Use the app's built-in remote function

TV Physical Buttons: Every Samsung TV has physical controls, typically on the back panel or bottom edge:

• Single joystick button: Push to select, tilt to navigate

• Multiple buttons: Look for power, volume, channel buttons

Voice Control (if previously configured): Samsung TVs with Bixby, Alexa, or Google Assistant can respond to voice commands even without the remote.

For more remote features, see Samsung TV remote voice control and use Samsung TV remote.

Controlling TV Without Remote

While waiting for a replacement or during troubleshooting:

• To change volume without remote, use TV's physical buttons or SmartThings app

• To change channel without remote, use physical buttons, SmartThings, or connected cable box remote

Samsung TV Model-Specific Troubleshooting: QLED, OLED, Neo QLED & Frame

Different Samsung TV technologies have different quirks. What works on a Crystal UHD might not apply to your Neo QLED, and OLED TVs have unique considerations. Here's model-specific guidance.

Identifying Your Samsung TV Model

Find your model number: Settings > Support > About This TV

Samsung model numbers decode like this:

• QN = QLED or Neo QLED

• QE = QLED (Europe)

• UN/UE = UHD/Crystal UHD

• KS = Older SUHD

• First two digits after letters = Screen size

• Year letter = Release year (A=2021, B=2022, C=2023, S=2024, etc.)

For detailed decoding, use the Samsung TV model number lookup tool.

Samsung QLED-Specific Issues

QLED TVs use quantum dot technology with full-array local dimming (FALD) backlighting.

Black crush in dark scenes: Local dimming can make dark areas too dark:

1. Settings > Picture > Expert Settings > Local Dimming > Low or Standard (not High)

2. Adjust Brightness up slightly

3. In game mode, some local dimming features disable automatically

Quantum dot color calibration: If colors appear oversaturated:

1. Settings > Picture > Picture Mode > Movie or Filmmaker Mode (most accurate)

2. Expert Settings > Color > reduce if needed

3. Expert Settings > Color Tone > Warm 2 for accurate whites

Game Mode optimization: For gaming with minimal input lag:

1. Settings > All Settings > Connection > Game Mode Settings > Game Mode > Auto or On

2. Use HDMI ports labeled "4K@120Hz" for next-gen consoles

3. If game mode keeps turning off, check Anynet+ settings and console HDMI output settings

Samsung Neo QLED-Specific Issues

Neo QLED uses mini-LED backlighting for more precise local dimming zones.

HDR settings optimization:

1. Settings > Picture > Expert Settings > HDR Mode > make sure source is HDR

2. Enable HDR+ Mode for SDR-to-HDR conversion (optional)

3. Adjust Brightness specifically for HDR content

One Connect Box troubleshooting: Premium Neo QLED models include external One Connect Box:

• Check both ends of the One Connect cable (also called Invisible Cable)

• Inspect for kinks, bends, or damage

• Try power cycling the One Connect Box separately

• Test without One Connect by connecting HDMI directly to TV (if ports available)

Samsung OLED-Specific Issues

Samsung's QD-OLED panels don't use backlights - each pixel produces its own light.

Burn-in prevention: Samsung OLEDs have automatic protection features:

1. Pixel Shift: Moves the image slightly to prevent static elements from burning in

2. Logo Brightness Detection: Automatically dims static logos

3. Panel Refresh: Runs automatically when needed (don't interrupt)

Screen Saver for OLED: Enable when leaving static content paused: Settings > All Settings > General > System Manager > Time > Screen Saver

For configuration options, see Samsung TV screensaver settings.

Brightness limitations: OLEDs won't get as bright as QLEDs, especially in well-lit rooms. This is normal physics, not a defect. For bright room viewing, consider window treatments or SDR content modes.

Samsung Frame TV-Specific Issues

The Frame operates in both TV Mode and Art Mode.

Art Mode not working:

1. Ensure TV is in Art Mode: Press Art Mode button on remote

2. Check motion sensor: Settings > General > Art Mode Options > Motion Detector Sensitivity

3. Clean the motion sensor area on TV front

Frame not switching modes:

• Motion Detector settings control automatic switching

• Night Mode determines behavior in darkness

• Matte display setting affects viewing angle and reflections

The Frame and decorative frames: If using a third-party Deco Frame or bezel, ensure it doesn't block the motion sensor or IR receiver.

Samsung Crystal UHD Issues

Budget-friendly Crystal UHD TVs have specific limitations that affect troubleshooting:

Lower brightness: Crystal UHD TVs typically reach 300-400 nits vs. 1000+ nits for QLED. HDR content won't pop as dramatically - this is normal behavior, not a defect. If HDR content looks washed out or dull, adjust HDR settings in Picture > Expert Settings, and consider that some HDR content simply won't look impressive on budget panels.

Motion blur in sports: Edge-lit backlighting on budget models handles fast motion differently than full-array backlighting:

1. Settings > Picture > Expert Settings > Picture Clarity Settings

2. Enable Motion Blur Reduction or Auto Motion Plus

3. Set to Custom and adjust Blur Reduction slider (start at 5, increase if needed)

4. Be aware: Motion smoothing can cause the "soap opera effect" on films - disable for movies

Upscaling quality: Lower-resolution content (720p, standard definition) may look softer than expected. Ensure Picture Clarity settings are optimized for your content type. For sports, use Sports picture mode. For older content, accept that the TV can only work with what it receives.

Contrast ratio limitations: Crystal UHD uses edge-lit LED backlighting with fewer dimming zones than QLED/Neo QLED. Black levels in dark scenes may appear grayish in dark rooms. This is a physics limitation of the technology, not a defect.

Samsung TV Maintenance: Prevent Problems Before They Start

Regular maintenance extends your TV's lifespan and prevents many common issues. These practices take minimal effort but make a real difference.

Optimal Placement Guidelines

Ventilation: Samsung TVs generate heat during operation. Ensure at least 4 inches of clearance around all vents (usually on the back and sides). Enclosed entertainment centers with closed backs trap heat and can cause thermal throttling or component damage.

Direct sunlight: Avoid placing your TV where direct sunlight hits the screen. UV exposure fades screens over time, and heat from sunlight can affect panel performance. OLED TVs are particularly sensitive to prolonged bright static images.

Temperature and humidity: Operate your TV between 50°F and 104°F (10°C to 40°C). Humidity extremes can damage electronics - avoid damp basements or rooms without climate control.

Mounting considerations: Wall-mounted TVs should use appropriately rated mounts. Ensure the mount handles your TV's weight plus a safety margin. Use cable management to prevent strain on ports.

Software Maintenance

Enable auto-updates: Settings > Support > Software Update > Auto Update > On

This ensures your TV receives security patches, bug fixes, and app compatibility updates automatically.

Monthly manual check: Even with auto-updates enabled, occasionally check manually: Settings > Support > Software Update > Update Now

App maintenance: Delete apps you don't use. Each installed app consumes storage and occasionally runs background processes.

Power Protection

Use a quality surge protector: Power surges from lightning or grid fluctuations can damage TV electronics instantly. A surge protector (not just a power strip) provides essential protection. Look for one rated for at least 2000 joules.

Replace surge protectors: Surge protectors degrade over time. Replace them every 3-5 years or after any major surge event (even if equipment seems fine).

Consider a UPS: In areas with frequent power fluctuations or outages, an Uninterruptible Power Supply (UPS) provides stable power and safe shutdown time.

Screen Care

Cleaning:

• Turn off and unplug the TV before cleaning

• Use only a clean, dry microfiber cloth

• For stubborn spots, slightly dampen the cloth with distilled water

• Never spray liquid directly on the screen

• Never use Windex, alcohol, ammonia, or abrasive cleaners

What damages screens:

• Paper towels (can scratch)

• Household cleaners (chemical damage)

• Excessive pressure while wiping

• Touching the screen frequently

Recommended Maintenance Schedule

Monthly Maintenance Routine (5 minutes):

1. Check for software updates: Settings > Support > Software Update > Update Now

2. Clear cache on frequently used apps

3. Delete any apps you haven't used in months

4. Run Network Status test to verify connection quality

5. Verify sound output is set correctly

Quarterly Deep Maintenance (15 minutes):

1. Unplug TV and all connected devices

2. Use dry microfiber cloth to clean screen

3. Use vacuum with soft brush attachment on vents

4. Inspect all cable connections - reseat any that feel loose

5. Check power strip/surge protector indicator lights

6. Reconnect everything and run Device Care diagnostic

For firmware management, the Samsung TV firmware update guide covers both automatic and manual update procedures.
