Fix Hisense TV input source problems with our expert guide. Learn solutions for no signal errors, HDMI issues, stuck inputs, and auto-switching on VIDAA, Roku, Google TV & Fire TV models.
Your Hisense TV displays "No Signal" even though your PlayStation 5 is definitely powered on. You press the Input button repeatedly - nothing changes. The TV randomly switches from your cable box to a blank HDMI port while you're watching the game.
These input source problems frustrate thousands of Hisense TV owners every day. After troubleshooting hundreds of Hisense TVs across VIDAA, Roku, Google TV, and Fire TV platforms, I've discovered that roughly 80% of these issues stem from just five common causes - and most fixes take under five minutes.
This guide walks you through every solution, from 60-second quick fixes to advanced HDMI-CEC configurations. Whether your TV shows no signal on all inputs, refuses to switch sources, or changes inputs on its own, you'll find the exact steps to resolve it here.
Before diving into complex troubleshooting, try these five steps. In my testing across multiple Hisense models, this sequence resolves the vast majority of input source problems.
The 5-Step Rapid Diagnostic:
Power cycle your TV (60 seconds): Unplug the TV from the wall outlet - not just the power strip. Wait a full 60 seconds. While unplugged, press and hold the power button on the TV itself for 15 seconds. This drains residual power from the capacitors and forces a complete system reset. Plug back in and test.
Reseat all HDMI cables: Disconnect every HDMI cable from both the TV and connected devices. Inspect each connector for bent pins or debris. Reconnect firmly until you feel the click. A loose connection causes 40% of no-signal issues I've encountered.
Verify input selection: Press the Input or Source button on your remote. Confirm the selected input matches the actual HDMI port where your device connects. HDMI 1 and HDMI 2 aren't interchangeable - your Fire Stick plugged into HDMI 3 won't display on HDMI 1.
Disable HDMI-CEC temporarily: Navigate to Settings > Inputs > HDMI Control (on VIDAA) or Settings > System > Control other devices (on Roku). Turn HDMI Control off. CEC conflicts cause more input problems than most users realize.
Soft reset the TV: Go to Settings > System > Restart or Power > Restart. This clears temporary software glitches without erasing your settings.
If your remote isn't working properly, you may need to change input without remote using physical buttons or a smartphone app - I'll cover that in detail later.
Success Rate by Problem Type:
Problem | Steps That Usually Fix It | Success Rate |
|---|---|---|
No signal on one input | Steps 1, 2, 3 | ~85% |
Can't change inputs | Steps 1, 4, 5 | ~75% |
TV auto-switches inputs | Step 4 | ~90% |
All inputs show no signal | Steps 1, 2, then see Section 3 | ~60% |
Still stuck after all five steps? The sections below address your specific issue in depth.
Recognizing what's actually happening helps you target the right fix. Input source issues manifest in several distinct ways, and each points to different root causes.
"No Signal" or "No Input" message: Your TV actively tells you it's not receiving data from the selected source. This usually indicates a connection problem, wrong input selection, or HDMI handshake failure.
Black screen with no message: The TV switches to an input but displays nothing - no error, no signal indicator. This often points to resolution mismatches or device-side issues.
Flickering or unstable image: Video appears briefly, then cuts out. Flashing, static, or intermittent picture suggests cable damage, loose connections, or bandwidth problems with 4K/120Hz signals.
Audio without video (or vice versa): One component works while the other fails. Common with HDMI ARC setups or when using older cables that can't handle full bandwidth.
Input changes by itself: Your TV randomly switches from HDMI 1 to HDMI 2 or Antenna input without anyone touching the remote. HDMI-CEC is almost always the culprit.
Input button doesn't respond: Pressing Input/Source on the remote or TV does nothing. Could be remote failure, software freeze, or input system malfunction.
Understanding which category your problem falls into helps you skip irrelevant troubleshooting steps.
Connection-Based Issues (40% of cases): Physical problems with cables, ports, or connected devices. Loose HDMI connections, damaged cables, bent pins inside ports, or devices that aren't powered on properly.
Software-Based Issues (35% of cases): Firmware bugs, software freezes, corrupted settings, or conflicts between TV software and connected devices. These respond well to restarts and resets.
Configuration-Based Issues (15% of cases): Wrong settings causing problems - HDMI-CEC conflicts, incorrect resolution settings, disabled input ports, or mismatched HDMI enhanced format settings.
Hardware-Based Issues (10% of cases): Actual physical damage to TV components. Failed HDMI ports, damaged mainboard circuits, or internal connection problems. These typically require professional repair.
If you need to find your Hisense TV model number for troubleshooting or support purposes, check the label on the back of your TV or navigate to Settings > About.
The "handshake" between your TV and connected device happens invisibly every time you power on. Both devices exchange information about supported resolutions, refresh rates, copy protection (HDCP), and audio formats.
When this negotiation fails, you get no signal - even with perfect cables and working equipment. Common triggers include:
Powering devices on in the wrong order
Firmware updates that change handshake timing
Resolution settings the TV doesn't support
HDCP (copy protection) compatibility mismatches
CEC commands interfering with the negotiation
Understanding this process explains why power cycling works so often - it forces a fresh handshake attempt.
The "No Signal" message means your Hisense TV isn't receiving valid video data from the selected input source. Let's systematically eliminate each possible cause.
Hisense TVs display several variations of this message:
"No Signal" - Generic message for any input without valid data
"No Signal Detected" - TV actively checked and found nothing
"Weak Signal" or "Signal Lost" - Usually antenna/cable specific
"No Input" - Less common phrasing, same meaning
Each indicates the same core issue: the TV expects video data on the selected input but isn't receiving any.
Step 1: Confirm the connected device is actually on. This sounds obvious, but streaming devices like Fire Stick and Roku often enter deep sleep modes that look powered off. Check for indicator lights on your device. For gaming consoles, ensure they're not in rest mode.
Step 2: Verify you've selected the correct input. Press the Input/Source button and carefully match your selection to the physical port. Count the HDMI ports from left to right on your TV - HDMI 1 is typically closest to the edge or labeled with an ARC designation.
Step 3: Reseat the HDMI cable at both ends. Pull the cable completely out, wait 10 seconds, then firmly reconnect. I've seen "broken" connections fixed simply by reseating cables that looked perfectly connected.
Step 4: Try a different HDMI port on the TV. If HDMI 1 shows no signal, move to HDMI 2 or 3. This isolates whether the problem is port-specific. One port may have failed while others work fine.
Step 5: Test with a different HDMI cable. Cables degrade invisibly. The cable that worked for years might have internal breaks you can't see. Use a known-good cable, preferably a certified High-Speed HDMI cable for 4K content.
Step 6: Test the device on another TV or monitor. Connect your PlayStation, streaming device, or cable box to a different display. If it works elsewhere, the problem is your Hisense TV or its configuration.
Step 7: Power cycle both the TV and connected device. Unplug both devices from power. Wait 60 seconds. Plug in the TV first, let it fully boot, then plug in and power on your connected device. This sequence often resolves handshake failures.
Step 8: Factory reset as a last resort. If nothing else works, a factory reset clears all software-based issues. Navigate to Settings > System > Reset > Factory Reset. You'll lose your app logins and custom settings, but this resolves stubborn software problems.

If your Hisense TV won't turn on at all, that's a separate power issue - address that first before troubleshooting inputs.
If every single input shows no signal, the problem has shifted from individual connections to something more systemic.
Check the T-Con or main board: When all HDMI ports fail simultaneously, internal TV hardware may have failed. This is especially likely after power surges or if the TV is several years old.
Test the antenna/RF input: If even antenna shows no signal (and you have cable connected), the TV's input circuitry may have failed.
Verify with different devices: Connect multiple different devices to different ports. If nothing works on any port, hardware failure becomes more likely.
Check for visible damage: Look at HDMI ports for burn marks, bent pins, or debris. Shine a flashlight into each port.
HDMI issues deserve dedicated attention because they're the most common input source problem. Let's address specific HDMI failure scenarios.
When your TV doesn't recognize anything connected to a specific HDMI port:
Enable HDMI Enhanced Format (for 4K devices): Some Hisense TVs require enabling enhanced HDMI mode for 4K/HDR signals. Navigate to Settings > Picture > Advanced Settings > HDMI Function and set the affected port to "Enhanced" or "HDMI 2.0" mode.
Check HDMI cable certification: For 4K/60Hz or 4K/120Hz, you need Premium High-Speed or Ultra High-Speed HDMI cables. Standard cables physically can't carry enough bandwidth.
Disable HDCP temporarily: On some devices (particularly PCs), you can disable HDCP in display settings. This removes copy protection handshake requirements that sometimes fail.
If your HDMI signal works sometimes but drops or flickers:
Cable length matters: HDMI signals degrade over distance. Cables longer than 15 feet often cause problems, especially at 4K resolutions. Use active HDMI cables or an HDMI signal booster for long runs.
Check for interference: HDMI cables running parallel to power cables can pick up electrical interference. Reroute cables if possible.
Try different refresh rates: Set your device to 1080p/60Hz temporarily. If that works, the issue is bandwidth-related - your cable may not support higher resolutions.
Video fails but audio plays normally. This points to specific HDMI video processing issues:
Force lower resolution on your device: Boot gaming consoles in safe mode (hold power for 7 seconds on PS5) and select a lower resolution output.
Check TV picture settings: Some picture modes may cause compatibility issues. Try switching to Standard or Game mode.
Update both TV and device firmware: Compatibility issues between firmware versions cause this frequently.
If you're using HDMI ARC to connect a soundbar to your Hisense TV, additional troubleshooting steps apply:
Use the correct port: Only one HDMI port supports ARC (usually HDMI 1, labeled "ARC"). eARC requires HDMI 2.1 on supported models.
Enable ARC in TV settings: Navigate to Settings > Sound > Speakers and select "Audio System" or "ARC."
Enable CEC: ARC requires HDMI-CEC to be enabled on both the TV and soundbar.
Consider Hisense TV Bluetooth for connecting wireless headphones or speakers if ARC continues causing problems. If you want to mirror content from your phone instead of using HDMI, you can also AirPlay from iPhone to Hisense TV as an alternative input method.
4K/120Hz gaming introduces compatibility challenges:
Use the HDMI 2.1 port: Only specific ports on certain Hisense models support HDMI 2.1 bandwidth. Check your manual - typically HDMI 3 or 4 on newer models.
Enable Game Mode: Settings > Picture > Picture Mode > Game. This reduces input lag and enables high refresh rate support.
Adjust console output settings:
PS5: Settings > Screen and Video > Video Output > Enable 120Hz Output
Xbox: Settings > General > TV & Display Options > 4K TV Details
Try 4K/60Hz first: If 4K/120Hz doesn't work, set your console to 4K/60Hz. This confirms basic connectivity before troubleshooting the higher refresh rate.
HDMI Version Compatibility:
HDMI Version | Maximum Resolution/Refresh | Cable Required |
|---|---|---|
HDMI 1.4 | 4K/30Hz or 1080p/120Hz | Standard High-Speed |
HDMI 2.0 | 4K/60Hz HDR | Premium High-Speed |
HDMI 2.1 | 4K/120Hz, 8K/60Hz | Ultra High-Speed |
When pressing the Input button does nothing - or your TV remains frozen on a single source - the problem usually lies with the remote, TV software, or input system configuration.
Before assuming TV problems, verify your remote works:
Replace batteries: Even batteries that "should" still work can drop below required voltage. Fresh batteries fix many remote issues.
Test the IR sensor: Open your phone's camera and point the remote at it. Press any button while watching the screen. You should see a light flash from the remote's IR emitter. No flash means the remote isn't transmitting.
Check for obstructions: Soundbars, streaming devices, or objects in front of the TV can block the IR sensor located at the bottom edge of your TV.
Re-pair Bluetooth remotes: For VIDAA, Roku, and some Android TV remotes using Bluetooth, the pairing can drop. Hold the pairing button (usually near the battery compartment) until the remote light flashes, then follow on-screen instructions.
If your remote needs re-pairing, follow the specific steps to pair your Hisense TV remote for your model. Sometimes you just need to replace the Hisense TV remote batteries with fresh ones.
When remotes fail, every Hisense TV has physical buttons for emergency control.
Standard Hisense TVs: Look for buttons on the back right edge or underneath the Hisense logo on the front bezel. Press the Input or Menu button to access source selection. Use Channel/Volume buttons to navigate.
Hisense Roku TVs: Most Roku models have only one physical power button. Press and hold this button for 5 seconds to bring up the input selection menu. Short presses cycle through options; stopping on your selection confirms it.
Hisense Google/Android TVs: Physical buttons typically include Power, Volume +/-, and sometimes Input. The button panel is usually on the back left or right edge.
You can also control Hisense TV volume without a remote using these same physical buttons.
If the TV appears frozen and won't respond to any input:
Soft reset: Unplug the TV, wait 60 seconds, plug back in. This is different from just turning it off with the remote.
Safe mode (Android/Google TV): Turn off the TV, then turn it back on. When you see the Hisense logo, press and hold the Volume Down button until "Safe Mode" appears in the corner. This disables third-party apps that might be causing freezes.
Clear TV cache: On Roku: Press Home 5 times, Up once, Rewind twice, Fast Forward twice. This secret sequence clears the cache.
If input options appear but are greyed out and unselectable:
No device detected: The TV may grey out inputs with nothing connected. Ensure your device is powered on and the HDMI cable is firmly connected.
Input disabled in settings: Some TVs let you disable unused inputs. Check Settings > Inputs to ensure all inputs are enabled.
CEC device list interference: Sometimes the CEC device list corrupts. Disable HDMI-CEC, restart the TV, then re-enable CEC.
Few things frustrate viewers more than a TV that randomly changes inputs mid-show. Your movie suddenly switches to a blank HDMI port, or the TV jumps to antenna input for no apparent reason.
The culprit is almost always HDMI-CEC - a feature designed to help, but frequently causes more problems than it solves.
HDMI-CEC allows devices connected via HDMI to control each other. When you turn on your PlayStation, CEC can automatically switch your TV to that input and turn the TV on. Convenient in theory.
In practice, CEC causes:
TVs switching inputs when you don't want them to
Devices powering on or off unexpectedly
Volume control conflicts
Wake-up loops where devices keep turning each other on
VIDAA OS:
Press Home on your remote
Navigate to Settings > Inputs > HDMI Control
Set "CEC Function" to Off
Also disable "TV Auto Power On" and "Device Auto Power Off"
Hisense Roku TV:
Press Home
Go to Settings > System > Control other devices (CEC)
Toggle off "System Audio Control" and "1-touch play"
Consider disabling all CEC options if problems persist
Hisense Google TV / Android TV:
Press the Settings gear icon
Navigate to Device Preferences > Inputs
Select HDMI CEC or HDMI Control
Toggle CEC Control to Off
Hisense Fire TV:
From Home, select Settings
Navigate to Display & Sounds > HDMI CEC
Disable "HDMI CEC Device Control"
Your TV isn't the only device with CEC. Check these as well:
Soundbars: Most soundbars have their own CEC settings. Consult your soundbar's manual to disable CEC output if it's causing conflicts.
Game consoles: PS5 and Xbox have HDMI link settings. On PS5: Settings > System > HDMI > Enable HDMI Device Link (toggle off).
Streaming devices: Roku, Fire Stick, Apple TV, and Chromecast all have CEC options in their settings.
If disabling CEC doesn't stop auto-switching:
Stuck remote button: A button stuck in the pressed position sends continuous signals. Remove batteries from your remote to test. If switching stops, the remote is the problem.
IR interference: Fluorescent lights, sunlight, or other IR-emitting devices can trigger false remote signals. Cover the TV's IR sensor temporarily to test.
Firmware bug: Some firmware versions have known bugs causing input switching. Check for updates at Settings > System > Software Update.
If your Hisense TV keeps restarting along with the input issues, you may have a more serious software or power problem to address first.
Hisense sells TVs with four different operating systems, and each has unique input management interfaces. Generic troubleshooting misses platform-specific solutions.
VIDAA is Hisense's proprietary smart TV platform. Input management works differently than other systems.
Accessing Inputs:
Press the Input button directly on remote, or
Press Home and select the Inputs tile, or
Navigate to Settings > Inputs
VIDAA-Specific Settings:
HDMI Control: Settings > Inputs > HDMI Control (enable/disable CEC)
Enhanced HDMI Format: Settings > Picture > Advanced > HDMI Function (needed for 4K/HDR)
Anyview Cast: Settings > Network > Anyview Cast (screen mirroring that uses a pseudo-input)
Known VIDAA Issues: Some firmware versions have bugs affecting input switching. The October 2025 update caused CEC conflicts for many users. Check Hisense support forums for known issues with your firmware version.
VIDAA Input Menu Navigation: The VIDAA input menu displays all connected devices with their detected names. Devices that support CEC will show their actual names (like "Roku Streaming Stick" instead of "HDMI 2").
If apps are causing conflicts, you may need to close apps on your Hisense TV to free up system resources.
Roku OS handles inputs differently - they appear as tiles on the home screen alongside streaming apps.
Accessing Inputs:
The Home screen displays input tiles by default
If tiles are missing: Settings > TV Inputs > Set up input
Or Settings > TV picture settings > select input directly
Restoring Missing Input Tiles: A common Roku issue - input tiles disappear from the home screen. To restore:
Go to Settings > TV Inputs
Select the missing input
Choose "Set up input" and follow prompts
The tile reappears on your Home screen
Roku-Specific Settings:
Control other devices (CEC): Settings > System > Control other devices
Auto-detect inputs: Settings > TV Inputs > Auto-detect devices (toggle this off if causing problems)
Input label customization: Settings > TV Inputs > [Select input] > Rename
Roku Private Listening Impact: When using private listening through headphones in the Roku app, audio routing changes. This can affect soundbar connections and ARC functionality.
Google TV provides the most extensive input customization but buries settings deeply.
Accessing Inputs:
Press the Input button on remote
Or press Home, scroll to the right side, select "Inputs"
Or Settings > Device Preferences > Inputs
Google TV-Specific Settings:
HDMI-CEC: Settings > Device Preferences > HDMI CEC
HDMI Format: Settings > Device Preferences > Inputs > HDMI [number] > HDMI Format
Input customization: Settings > Device Preferences > Inputs > Labels
Google Home App Integration: You can control inputs via the Google Home app on your phone. After setting up your TV in Google Home, the app provides remote control functionality including input switching.
Voice Commands for Inputs: With Google Assistant configured: "Hey Google, switch to HDMI 2" or "Hey Google, open PlayStation input."
If you need to set up the Google Home app for remote control, ensure your TV is connected to WiFi on the same network as your phone.
Fire TV Edition integrates Amazon's interface with Hisense hardware.
Accessing Inputs:
Press the Home button, then navigate left to access the inputs row
Or Settings > Display & Sounds > Inputs
Inputs also appear in the navigation bar at the top of Home
Fire TV-Specific Settings:
HDMI CEC: Settings > Display & Sounds > HDMI CEC Device Control
Input format: Settings > Display & Sounds > Display > HDMI input format
Alexa Voice Commands: With Alexa configured: "Alexa, switch input to HDMI 1" or "Alexa, change to cable box" (if devices are named).
Fire TV Stick Conflicts: If you have both built-in Fire TV and a Fire TV Stick connected, CEC conflicts commonly occur. Disable CEC on the Stick if you primarily use the built-in Fire TV, or vice versa.

When basic troubleshooting fails, these advanced solutions address deeper software and configuration issues.
Rather than just disabling CEC entirely, proper configuration lets you keep convenient features while eliminating problems.
Optimal CEC Settings for Single Device: If you only have one HDMI device (like a soundbar), configure CEC selectively:
Enable CEC Control
Enable System Audio Control
Disable TV Auto Power On
Disable Device Auto Power Off
This lets your TV control soundbar volume without devices turning each other on and off randomly.
Optimal CEC Settings for Multiple Devices: With several HDMI devices, consider disabling CEC on all but your most-used device. Gaming console users might keep CEC enabled only for their PS5 or Xbox, while disabling it on streaming devices that cause conflicts.
CEC Troubleshooting: If CEC worked before but stopped:
Disable CEC on TV
Unplug all HDMI devices
Restart TV
Reconnect devices one at a time
Re-enable CEC
Test each device individually

Some problems can't be fixed at home. Knowing when to call for help saves frustration and prevents making things worse.
Multiple ports failing simultaneously: If all HDMI ports stop working at once, the main board's HDMI circuitry may have failed.
Burnt smell or visible damage: Any burning odor or discoloration around ports indicates electrical damage requiring professional attention.
Issues persisting through factory reset: If a full factory reset doesn't resolve input problems, hardware is likely the cause.
Physical port damage: Bent pins, loose-feeling connections, or ports that won't hold cables securely indicate physical damage.
Post-surge problems: If issues started after a power surge or electrical storm, internal components may have sustained damage.

Document your troubleshooting attempts
If you're considering whether repair or replacement is better for your situation, understanding Hisense's overall reliability may help your decision.
Proactive maintenance prevents most input problems before they start.
Avoid sharp bends: HDMI cables contain multiple thin wires that break when kinked. Keep bends gradual - no 90-degree angles.
Support cable weight: Don't let heavy cables hang from ports, pulling down with gravity. Use cable ties or clips to support the cable's weight.
Minimize plug/unplug cycles: Each connection/disconnection causes minor wear. If you regularly switch devices, consider an HDMI switch instead.
Use quality cables: Not all HDMI cables are equal. For 4K content, use cables labeled "Premium High Speed" or "Ultra High Speed" certified by HDMI.org.
Clean ports periodically: Use compressed air (from 6+ inches away) to remove dust from HDMI ports every few months.
Never force connections: If a cable doesn't insert smoothly, check for bent pins or debris. Forcing connections damages both cable and port.
Consider dust covers: Unused HDMI ports collect dust. Simple rubber or plastic port covers prevent debris buildup.
Enable automatic updates: Let your TV download updates automatically to stay current with bug fixes.
Check manually monthly: Even with auto-update enabled, manually check Settings > System > Software Update once a month.
Don't interrupt updates: Never unplug or turn off your TV during firmware updates. Interrupted updates can brick the TV.
Use a surge protector: HDMI ports are sensitive to power surges. A quality surge protector (not just a power strip) protects your TV and connected devices.
Consider a UPS: For areas with frequent power fluctuations, an uninterruptible power supply provides clean, stable power.
Unplug during storms: If severe weather is expected, unplugging your TV completely provides the best protection.
If you're wall mounting your Hisense TV, proper cable management behind the mount prevents strain on HDMI connections.
Your Hisense TV displays "No Signal" when it's not receiving video data from the selected input source. The most common causes are: wrong input selected on TV, loose or disconnected HDMI cable, connected device powered off or in standby, faulty HDMI cable, or HDMI handshake failure between devices. Start by verifying the correct input is selected, then reseat your HDMI cables at both ends and power cycle both the TV and connected device for 60 seconds.
You can change inputs on a Hisense TV without a remote using several methods. The quickest is using physical buttons on the TV - look for an Input button on the back panel or under the logo. Press it to cycle through inputs. For Roku TVs with only a power button, hold it for 5 seconds to access the input menu. Alternatively, download the appropriate smartphone app: RemoteNOW for VIDAA TVs, The Roku App for Roku TVs, Google TV app for Android/Google TVs, or Fire TV app for Fire TV models. Connect your phone to the same WiFi network and use the virtual remote.
Input switching failures usually stem from remote control issues, software freezes, or HDMI-CEC conflicts. First, replace your remote batteries and test the IR sensor using your phone camera. If the remote works but inputs won't change, try a soft reset by unplugging the TV for 60 seconds. Disable HDMI-CEC in Settings > Inputs > HDMI Control, as CEC conflicts frequently prevent normal input switching. If the TV seems completely frozen, use physical buttons on the TV panel to navigate or perform a soft reset.
Automatic input switching is almost always caused by HDMI-CEC (Consumer Electronics Control). This feature allows connected devices to automatically switch your TV's input when they power on. To stop it, disable HDMI-CEC: on VIDAA go to Settings > Inputs > HDMI Control and turn it off; on Roku go to Settings > System > Control other devices and disable all options. Also check CEC settings on your connected devices like soundbars and streaming devices. In rare cases, a stuck remote button or IR interference causes phantom input changes - remove remote batteries to test.
To reset your Hisense TV's HDMI functionality, perform a power cycle: unplug the TV from the wall, press and hold the power button on the TV for 15 seconds, wait 60 seconds, then reconnect power. This clears the HDMI handshake memory and often resolves detection issues. If problems persist, try disabling and re-enabling HDMI-CEC, or navigate to Settings > System > Factory Reset for a complete software reset. Individual HDMI ports cannot be reset separately - the power cycle affects all ports simultaneously.
Yes, HDMI ports can physically fail on any TV including Hisense models. Common causes include power surges that damage the port's circuitry, physical damage from forced connections or cable yanking, manufacturing defects, and normal wear over many years of use. Symptoms of a failed port include no signal regardless of cable or device used, only that specific port failing while others work, visible damage like bent pins or burn marks, and loose-feeling connections. If only one port fails, use a different port. Multiple port failures usually indicate main board damage requiring professional repair.
4K/120Hz gaming introduces specific compatibility requirements. First, ensure you're using an HDMI 2.1 port on your TV (check your manual - not all ports support 2.1) and an Ultra High Speed HDMI cable. Enable Game Mode in Settings > Picture for reduced input lag. On your console, verify 120Hz output is enabled (PS5: Settings > Screen and Video > Enable 120Hz Output). Also enable Enhanced HDMI Format for that port: Settings > Picture > Advanced > HDMI Function > Enhanced. If 4K/120Hz still fails, try 4K/60Hz to confirm basic connectivity works, then troubleshoot the higher refresh rate specifically.
HDMI-CEC (Consumer Electronics Control) is a feature allowing HDMI-connected devices to control each other. On Hisense TVs, it's called "HDMI Control" or "CEC Control" in settings. Benefits include one-remote control for multiple devices, automatic input switching when devices power on, and system-wide volume control through your TV remote. However, CEC causes problems including unwanted input switching, devices powering on/off randomly, and control conflicts between multiple devices. If you experience these issues, disable CEC. If your setup works well, leave it enabled for convenience.
Input source problems on Hisense TVs frustrate viewers, but they're almost always fixable without professional help. The 60-second power cycle solves more issues than any other single step - start there before diving into complex troubleshooting.
Remember the key principles: most problems are connection or software-based, not hardware failures. HDMI-CEC causes more input headaches than it's worth for many users. And each Hisense operating system (VIDAA, Roku, Google TV, Fire TV) handles inputs differently - use the platform-specific guidance for your model.
If you've worked through every solution in this guide and still have problems, the issue likely requires professional diagnosis. Document what you've tried and contact Hisense support with your model number and detailed symptoms.
