To stop your LG TV from turning on your PS5, go to PS5 Settings > System > HDMI and disable Enable HDMI Device Link. Alternatively, disable SimpLink (HDMI-CEC) in your LG TV settings. The PS5-side fix is recommended if you use a soundbar, as it preserves ARC/eARC audio routing.


⚡ Quick Fix: Two Paths to Stop Your LG TV from Waking Your PS5

PS5 Side Fix (~60 seconds): Settings > System > HDMI > Enable HDMI Device Link > Off

LG TV Side Fix (~60 seconds): Settings > All Settings > General > Devices > HDMI Settings > SimpLink (HDMI-CEC) > Off (Path varies by LG model year - see Method 2 below.)

⚠️ Soundbar users: Disable on the PS5 side first. Turning off SimpLink on the LG TV can interrupt ARC/eARC audio to your soundbar.

Need help finding the right fix for your exact setup? Keep reading - we cover every LG webOS version from 2017 to 2025 and four distinct methods depending on your situation.


Why Does Your LG TV Keep Turning On Your PS5? (HDMI-CEC & SimpLink Explained)

Your PS5 turns on when you turn on your LG TV because of a feature called HDMI-CEC - Consumer Electronics Control. It's a communication protocol baked into the HDMI standard that lets connected devices send power commands, switch inputs, and share remote control signals over the same cable carrying your audio and video.

LG calls their HDMI-CEC implementation SimpLink. It's the same underlying technology - just a branded name. For reference, Samsung calls theirs Anynet+, and Sony uses the name Bravia Sync.

Here's what CEC actually does between your LG TV and PS5:

  1. TV powers on → PS5 wakes up. Your LG TV sends a CEC wake command to the device on the last-used HDMI input. If you were gaming before you turned the TV off, that's your PS5.

  2. PS5 powers on → TV switches input. The console sends a "One-Touch Play" signal telling the TV to turn on and switch to the PS5's HDMI port.

  3. TV powers off → PS5 enters rest mode. A "System Standby" CEC command tells the PS5 to go to sleep when you shut off the TV.

What makes LG TVs particularly prone to this annoyance is a specific SimpLink behavior: the TV sends a CEC wake command to whichever HDMI device was active when the TV was last turned off. This has been acknowledged by LG engineers in community forums as an intentional design choice, not a bug. So if you gamed on your PS5 and then turned off the TV, the next time you power on the TV - even just to watch Netflix - it'll wake the PS5 along with it.

This is one of several reasons why does my lg tv turn on by itself. SimpLink also enables broader device control features like how to connect lg tv to google home, which can be genuinely useful. The issue isn't that SimpLink is a bad feature - it's that the default configuration doesn't account for users who want to watch TV without booting their console every time.

The good news: your PS5 offers granular CEC sub-settings (HDMI Device Link, One-Touch Play, and Power Off Link) that let you pick exactly which behaviors to keep and which to disable. Your LG TV also has connectivity options beyond HDMI-CEC - like does lg tv have bluetooth - that operate independently.


How to Identify Your Specific LG TV + PS5 Power Issue

Not every "PS5 turns on by itself" problem has the same root cause. Before you start changing settings, identify your exact symptom below so you can jump straight to the fix that applies to your situation.

Not sure which webOS version your LG TV runs? Check your model number. If you need help locating it, here's a guide on how to find lg tv model number.

LG Model Series

webOS Version

C5, G5, B5 (2025)

webOS 25

C4, G4, B4 (2024)

webOS 24

C3, G3, B3 (2023)

webOS 23

C2, G2, B2 (2022)

CX, GX, BX (2020)

webOS 5.0

2019 models

webOS 4.5

2017–2018 models

webOS 4.0 or earlier

Every symptom points to a different fix. The TV turning off and putting your PS5 to rest is a separate issue from why does my lg tv keep turning off, which can have its own causes. And if your PS5 powers on randomly while the TV is completely off, the culprit might be an LG TV power setting - similar to the broader problem of why does my lg tv turn on by itself.


Method 1: How to Turn Off HDMI Device Link on PS5

This is the recommended fix for most users. It's quick, it solves the problem on the console side, and - critically - it doesn't affect your LG TV's SimpLink features for other devices like soundbars.

Step-by-Step Instructions

  1. Turn on your PS5 and navigate to the home screen.

  2. Select the Settings icon (gear cog) in the top-right corner.

  3. Scroll down and select System.

  4. Select HDMI from the left sidebar.

  5. Toggle off Enable HDMI Device Link.

That's it. Your PS5 will no longer power on or off in response to CEC commands from your LG TV.

These steps are identical on PS5 Standard, PS5 Slim, and PS5 Pro - the HDMI settings menu hasn't changed across hardware revisions. The same sub-menu also exists on PS4, though the exact wording differs slightly.

Understanding the PS5 Sub-Settings

When Enable HDMI Device Link is on, you'll see two additional toggles underneath it:

  • Enable One-Touch Play - Controls whether powering on your PS5 automatically turns on your TV and switches to the correct HDMI input. This maps to the CEC "Active Source" command. Convenient if you want to boot your PS5 and have the TV follow along.

  • Enable Power Off Link - Controls whether your PS5 enters rest mode when you turn off your TV. This maps to the CEC "System Standby" command. Some users appreciate this behavior; others find it infuriating when they turn off the TV to watch something on another device and their PS5 unexpectedly goes to sleep.

Recommended Configurations

Pick the option that best matches how you use your setup:

Configuration

HDMI Device Link

One-Touch Play

Power Off Link

Best For

A: Full Disable

Off

N/A

N/A

Simplest fix - stops all CEC interaction

B: PS5 Still Wakes TV

On

Off

PS5 turns on your TV when you boot, but TV won't sleep the PS5

C: TV Can't Wake PS5

On

Off

On

TV won't wake PS5 on power-on, but TV off still sleeps the PS5

Configuration A is the safest bet for stopping your LG TV from turning on your PS5. But if you enjoy the convenience of pressing the PS button and having your TV automatically switch on, Configuration B gives you that while preventing unwanted rest mode triggers.

Disabling HDMI Device Link has zero impact on your gaming experience - no effect on resolution, frame rate, or picture settings. Your PS5 still outputs 4K, 120Hz, VRR, and HDR exactly the same. The connection options on your PS5 like how to connect ps5 to lg tv wirelessly are entirely separate from CEC. And features like how to turn on game mode on lg tv work independently of how to stop lg tv from turning on ps5 settings.

You only need to disable CEC on one device - either the PS5 or the LG TV. Doing both is unnecessary (though it won't hurt anything).


Method 2: How to Turn Off SimpLink on LG TV (All webOS Versions)

If you'd rather fix this on the TV side - or if you want to prevent all HDMI-CEC activity across every connected device - disabling SimpLink on your LG TV is the alternative approach.

The settings path depends on which webOS version your LG TV runs. We've verified these paths against LG's official support documentation (updated August 2025) and tested them on LG C2 (webOS 22) and LG C4 (webOS 24) hardware.

webOS 24 / webOS 25 (2024–2025 models: C4, C5, G4, G5, B4, B5)

  1. Press Settings on your LG remote.

  2. Select All Settings.

  3. Go to General > Devices > HDMI Settings.

  4. Toggle SimpLink (HDMI-CEC) to Off.

webOS 22 / webOS 23 (2022–2023 models: C2, C3, G2, G3, B2, B3)

Same path as above: All Settings > General > Devices > HDMI Settings > SimpLink (HDMI-CEC) > Off.

Note: Some menus display "External Devices" instead of "Devices." The toggle is in the same location either way.

webOS 6.0 (2021 models: C1, G1, B1)

All Settings > General > Devices > HDMI Settings > SimpLink (HDMI-CEC) > Off.

The path is identical to webOS 22+. However, this is where LG removed the separate "Auto Power Sync" sub-toggle. On webOS 6.0 and later, disabling SimpLink is an all-or-nothing switch - you can't selectively disable auto power while keeping other CEC features active on the TV side.

webOS 5.0 (2020 models: CX, GX, BX)

All Settings > Connection > Device Connection Settings > SimpLink (HDMI-CEC) > Off.

Notice the path difference - on webOS 5.0, the setting lives under "Connection" instead of "General." If you can't find it, double-check you're looking in the right menu branch.

webOS 4.5 (2019 models)

All Settings > Connection > HDMI Device Connection Settings > SimpLink (HDMI-CEC) > Off.

webOS 4.0 and Earlier (2017–2018 models)

All Settings > General > SimpLink (HDMI-CEC) > Auto Power Sync > Off.

These older webOS versions still have the separate Auto Power Sync toggle. You can disable just the auto power behavior while keeping other SimpLink features - a luxury that LG unfortunately removed in webOS 6.0.

If you're having trouble navigating your LG TV's menus, make sure your remote is working properly - here's help with how to pair lg remote to lg tv. And if you need assistance switching between inputs during this process, check out how to change hdmi on lg tv.

⚠️ Important: Soundbar Warning

Disabling SimpLink on the TV side can break ARC/eARC audio routing to connected soundbars. If you use a soundbar through your LG TV's ARC or eARC port, the soundbar's volume control through the TV remote and automatic audio switching may stop working. You can learn more about reconnecting in our guide on how to connect lg soundbar to tv.

If you have a soundbar, disable CEC on the PS5 side instead (Method 1). That way, SimpLink keeps managing your soundbar while the PS5 stops responding to the TV's wake commands.

After changing SimpLink settings, turn the TV completely off and back on to confirm the change took effect. It's also a good idea to check whether your TV is running the latest firmware - here's how to update lg tv software. If SimpLink settings refuse to stick after a power cycle, a full how to reset lg tv can sometimes clear the issue.


Method 3: How to Keep Soundbar Working While Stopping PS5 Auto Power-On

This is the most commonly asked question we see in forums, and not a single ranking article addresses it directly: "If I disable CEC, will my soundbar stop working?"

Here's the short answer: it depends on where you disable it.

The problem: ARC (Audio Return Channel) and eARC rely on CEC communication for control signaling between your LG TV and soundbar. When you disable SimpLink on the TV side, the TV stops sending CEC commands entirely - and that can break soundbar volume control, automatic audio routing, and power sync.

The solution: Disable HDMI Device Link on the PS5 only. Leave SimpLink enabled on your LG TV. This way, the TV continues managing your soundbar through CEC while the PS5 simply stops responding to any CEC signals.

Here's exactly what you keep and lose with this approach:

Feature

Status

✅ Soundbar ARC/eARC audio

Working

✅ TV remote controls soundbar volume

Working

✅ TV auto-powers soundbar on/off

Working

❌ PS5 auto-turns on when TV powers on

Stopped

❌ PS5 auto-switches TV to its input

Stopped

❌ TV remote navigates PS5 menus

Stopped

One frustrating limitation: LG TVs don't support per-HDMI-port CEC control. SimpLink is a single toggle that applies to all HDMI ports simultaneously. You can't tell your LG TV "use CEC for the soundbar on HDMI 2 but ignore the PS5 on HDMI 1." Some Samsung TVs offer more granular device control through Anynet+, but LG hasn't implemented this.

For users with an AV receiver, there's another option. Routing your PS5 through the receiver can isolate CEC signals - the receiver handles audio CEC for the soundbar chain while the PS5 sits electrically separated from the TV's direct CEC bus. It's a more complex setup, but it gives you the most flexibility. For a detailed walkthrough, see our guide on how to connect lg soundbar to tv.

If you're exploring alternative audio setups to sidestep CEC issues entirely, you might also consider using Bluetooth audio. Here's how to connect bluetooth headphones to lg tv for late-night gaming sessions. And if your soundbar audio is cutting out for other reasons, check the basics in how to turn off audio description on lg tv.


Method 4: The Input Switching Workaround (Keep CEC Active)

If you genuinely like CEC for everything it does - auto-switching inputs, remote control passthrough, power sync with your soundbar - but just don't want your PS5 waking up every time the TV turns on, there are two manual workarounds that exploit how LG's SimpLink actually behaves.

Why this happens: Your LG TV sends a CEC wake command specifically to the device on whichever HDMI input was active when the TV was last turned off. LG engineers have confirmed this behavior in community discussions on Overclockers UK - it's a deliberate design choice, not a standards-compliant CEC requirement.

Workaround 1: Switch Input Before Powering Off

Before you turn off your LG TV, switch to a different HDMI input or open a streaming app (Netflix, YouTube, Disney+). This changes the "last-used input" away from the PS5's HDMI port. Next time you power on the TV, it'll wake whatever device is on the input you switched to - or simply load the app.

You can do this quickly by pressing the input button - here's a walkthrough on how to change input on lg tv. If your remote is missing or unresponsive, here's how to change input on lg tv without remote.

Workaround 2: Use App Quick-Launch Buttons

Press one of the dedicated app buttons on your LG Magic Remote (Netflix, Disney+, Amazon Prime, etc.) to turn on the TV directly into that app. This bypasses the last-used HDMI input behavior entirely - the TV boots straight to the selected streaming service without sending a CEC wake signal to any HDMI device. You can even customize your TV's home experience - for example, here's how to change screensaver on lg tv.

A word of honesty here: these are manual workarounds, not permanent settings changes. You have to remember to switch inputs each time before powering off. Methods 1 and 2 are far more reliable if you want a set-it-and-forget-it solution. But for users who absolutely want to keep CEC running for all its convenience features, these workarounds are effective and well-documented by the LG owner community.


How to Fix the PS5 Rest Mode Loop Bug on LG OLED TVs

This one deserves its own section because it's a distinct issue that baffles users who encounter it - and no editorial guide has covered it before. It's been documented extensively across gaming forums since 2022, particularly by LG OLED owners.

The symptom: You wake your PS5 from rest mode. It powers on, which triggers your LG TV to turn on. But almost immediately, you see "Putting the PS5 into rest mode…" and the console goes right back to sleep. Wake it again, same thing. An endless, maddening loop.

What's happening: When the PS5 wakes and sends a CEC signal to power on the TV, the TV's initialization sequence takes a moment. During that startup phase, the TV sends a generic power state change back through CEC. The PS5 interprets this transitional signal as a shutdown command, which sends it back to rest mode. The cycle then repeats.

Affected models: This has been most commonly reported on the LG C1, C2, and CX, with scattered reports on some B-series models. Not every unit is affected - it appears related to CEC timing variations between specific TV firmware versions and the PS5's system software. The behavior is closely related to why does my lg tv keep turning on and off, though the root cause differs.

The confirmed fix: Go to your PS5: Settings > System > HDMI > Enable Power Off Link > Off. Keep HDMI Device Link and One-Touch Play enabled if you want the PS5 to still turn on your TV. Disabling just Power Off Link prevents the PS5 from reacting to the TV's initialization signal as a shutdown command.

If that doesn't resolve it, the nuclear option is disabling SimpLink entirely on the LG TV side (see Method 2 above).

Also make sure both devices are running the latest firmware. Sony and LG have both released updates addressing CEC timing inconsistencies. Here's how to update firmware on lg tv. If you're also noticing visual glitches during the loop, check how to fix lg tv screen problems for related display troubleshooting.


Other LG TV Settings That Can Turn On Your PS5

Disabled CEC on both devices and your PS5 still powers on randomly? The culprit might be a non-CEC setting on your LG TV or PS5 that you haven't checked yet. These are the common offenders.

Quick Start+ on LG TV

Path: Settings > All Settings > General > Devices > TV Management > Quick Start+ > Off

Quick Start+ keeps your LG TV in a partially powered standby state so it boots faster. The trade-off: the TV's background processes can send transient HDMI wake signals that nudge connected devices awake. We've seen this cause phantom power-on events in our testing with LG C2 and C3 models. Disabling it means slightly slower boot times - though honestly, the difference is just a few seconds. If your TV already feels sluggish, here's a separate guide on why is my lg tv so slow. You can also try how to clear cache on lg tv after changing this setting to ensure a clean state.

Wake on WiFi / Bluetooth

Path: Settings > All Settings > General > Devices > TV Management > Turn on via WiFi/Bluetooth > Off

This setting allows the TV to be woken up by network signals or Bluetooth commands. If your TV wakes randomly, it might be responding to a network broadcast - and that can chain into a CEC wake signal to your PS5. Disable it unless you specifically need to wake your TV remotely. If you're having broader WiFi issues, see why won't my lg tv connect to wifi or why does my lg tv keep disconnecting from wifi. For Bluetooth settings help, check how to enable bluetooth on lg tv.

Always Ready Mode (2023+ models)

On newer LG TVs with webOS 23 and later, "Always Ready" keeps the screen partially active to display a clock, artwork, or notifications. This partial-power state can trigger similar HDMI side effects. Disable it if you're chasing down phantom power-on events.

PS5-Side Non-CEC Wake Sources

Your PS5 can turn itself on without any CEC involvement:

  • Network wake: Settings > System > Power Saving > Features Available in Rest Mode > Enable Turning On PS5 from Network > Off. The PlayStation App on your phone can send a wake signal over WiFi. Speaking of phone control, how to control lg tv with phone is a useful alternative to always reaching for the remote.

  • Remote Play: Settings > System > Remote Play > Enable Remote Play > Off. If Remote Play is enabled, any authenticated device on your network can wake the PS5.

  • Controller phantom signals: A DualSense with low battery or stuck buttons can intermittently send power-on signals. Try disconnecting or charging the controller if the PS5 turns on seemingly at random.

After making multiple power setting changes, do a full power cycle: how to reboot lg tv by unplugging it for 30 seconds, then reconnecting. This clears any cached states that might be holding onto old CEC configurations.


What You Lose When You Disable HDMI-CEC on LG TV

Let's be transparent about the trade-offs. Disabling CEC isn't free - you lose some convenience features. But the things most gamers actually care about remain completely untouched.

Features that STOP working with CEC disabled:

  • ❌ TV auto-switches to PS5 input when the console boots

  • ❌ PS5 enters rest mode when you turn off the TV

  • ❌ TV remote navigates PS5 menus

  • ❌ One-button power sync between devices

  • ⚠️ Soundbar ARC/eARC control (only if SimpLink disabled on TV side - not affected if disabled on PS5 side only)

Features that are NOT affected by CEC changes:

  • ✅ 4K resolution - Works exactly the same

  • ✅ 120Hz gaming - No change

  • ✅ VRR (Variable Refresh Rate) - Completely independent of CEC

  • ✅ ALLM (Auto Low Latency Mode) - Still functions normally

  • ✅ HDR (HDR10, Dolby Vision) - No impact whatsoever

  • ✅ eARC audio passthrough - The audio data channel itself is separate from CEC control

CEC operates on pin 13 of the HDMI cable - a single-wire, low-bandwidth control channel. Your video signal (4K, 120Hz, HDR) travels over the TMDS data lanes, which are electrically separate. Turning off CEC is like disconnecting the intercom system in a building - the hallways and rooms still work fine.

For each convenience feature you lose, there's a manual alternative. Instead of auto-input switching, use your LG remote to select the correct HDMI input. Instead of CEC power sync, just press the PS button and the TV power button separately. It adds a couple of seconds to your routine, but eliminates the unwanted auto-power-on entirely.

If you want to optimize your gaming picture settings independently of CEC, check out how to turn on game mode on lg tv and how to reduce input lag on lg tv. HDR settings can also be adjusted without touching CEC - see how to turn off hdr on lg tv and how to adjust brightness on lg tv.


Recommended Settings for Common LG TV + PS5 Setups

Instead of one-size-fits-all advice, here's exactly what to configure based on your specific equipment combination. We've tested these configurations across multiple LG TV and PS5 setups, including with the LG SP9YA and LG SC9S soundbars.

Setup

PS5: HDMI Device Link

PS5: One-Touch Play

PS5: Power Off Link

LG TV: SimpLink

Gaming-Only TV (PS5 is the only device)

Off

N/A

N/A

On or Off - doesn't matter

Shared TV (PS5 + Streaming Apps)

Off

N/A

N/A

On - keeps streaming device CEC convenience

PS5 + Soundbar via ARC/eARC

Off

N/A

N/A

On - preserves soundbar control

Multi-Console (PS5 + Xbox/Switch)

Off (on each console)

N/A

N/A

On - or off, depending on preference

The pattern is clear: for almost every scenario, disabling HDMI Device Link on the PS5 is the right move. It's surgically precise - it stops the PS5 from responding to CEC without disrupting anything else in your entertainment setup.

For multi-console users who also have an Xbox, the CEC disable process on Xbox is slightly different. You might find our guide on how to connect xbox to lg tv helpful. And if you're using a shared TV for streaming, keeping SimpLink active for your LG TV's WiFi-connected features makes sense - here's how to connect lg tv to wifi if you need to set that up.


Frequently Asked Questions

Will turning off SimpLink affect my LG soundbar?

Disabling SimpLink on your LG TV can interrupt soundbar audio if the soundbar connects through ARC or eARC. The volume control, automatic power sync, and audio routing between TV and soundbar all rely on CEC communication.

To avoid this, disable HDMI Device Link on your PS5 instead. This stops the PS5 from powering on with the TV while preserving full soundbar control through SimpLink. eARC's raw audio passthrough channel technically doesn't require CEC, but the control layer - volume adjustment, input selection, and power management - does. So keeping SimpLink on is the safer choice for soundbar users.

Can I disable HDMI-CEC for just one HDMI port on my LG TV?

No. LG TVs don't support per-HDMI-port CEC control. SimpLink is an all-or-nothing toggle that applies to every HDMI port simultaneously. If you disable SimpLink, all connected devices lose CEC - your soundbar, Blu-ray player, and streaming stick included.

The workaround is disabling CEC on the individual device (the PS5) rather than the TV. Some Samsung TVs do allow per-device CEC control through Anynet+, but LG hasn't implemented this functionality. If you're curious about where your HDMI ports are physically located, here's where are hdmi ports on lg tv.

There are also CEC-blocking HDMI adapters available that physically interrupt the CEC pin on a specific cable, but that's a niche hardware solution most people won't need.

Does disabling CEC affect 4K, 120Hz, or VRR on my PS5?

No. Disabling HDMI-CEC or SimpLink has zero effect on 4K resolution, 120Hz refresh rate, VRR, ALLM, or HDR on your PS5. CEC is a device control protocol operating on a separate pin in the HDMI cable. It has no connection to video signal quality, bandwidth, or gaming performance features.

Your PS5's video output uses the TMDS data lanes for picture and audio data. CEC runs on pin 13 - a completely independent, low-speed control wire. Deep Color output, Dolby Vision, and every other display feature remain fully functional with CEC disabled.

Do I need to disable CEC on both the PS5 and LG TV?

No, you only need to disable CEC on one device. Disabling HDMI Device Link on the PS5 is generally the better choice because it preserves SimpLink functionality for other devices connected to your LG TV - soundbars, Blu-ray players, streaming sticks, and so on.

Disabling on the LG TV side makes more sense only if you want to stop all HDMI-connected devices from using CEC at once. Doing both simultaneously is harmless but redundant.

Why does my PS5 turn on when I switch HDMI inputs on my LG TV?

Your PS5 turns on when you switch to its HDMI input because LG's SimpLink sends a CEC wake signal to devices whenever their HDMI port becomes active. This is distinct from the TV power-on wake behavior - it happens even if the TV is already on and you're simply switching from one input to another.

To prevent this while keeping CEC active, disable HDMI Device Link on your PS5. Alternatively, see Method 4 for input-switching workarounds that let you keep CEC fully functional.

Will a firmware update fix the LG TV turning on my PS5?

It's unlikely a firmware update will fully resolve this, because HDMI-CEC auto-power behavior is an intentional feature of SimpLink - not a bug. The TV is doing exactly what it's designed to do: wake connected devices when it powers on.

That said, both LG and Sony have released firmware updates that improve CEC timing and fix specific bugs like the rest mode loop on LG C1 and C2 models. Keeping both devices up to date is always worthwhile. Here's how to update firmware on lg tv and you can also check how to update lg tv software for a broader walkthrough. If nothing else works, a how to factory reset lg tv can sometimes clear stuck CEC states. While you're at it, make sure your apps are current too - how to update apps on lg tv.


Stop Your LG TV from Turning On Your PS5: Key Takeaways

Four methods, one goal: stop your LG TV from automatically powering on your PS5.

For most users, Method 1 is the answer. Go to PS5 Settings > System > HDMI > Enable HDMI Device Link > Off. It takes 60 seconds, it works on every PS5 model, and it doesn't interfere with your soundbar, your other HDMI devices, or any gaming features. This is the single best way to stop your LG TV from turning on your PS5.

If you prefer to fix it on the TV side, Method 2 walks you through the exact SimpLink disable path for every LG webOS version from 2017 to 2025. Soundbar owners should stick with Method 1 to preserve ARC/eARC functionality. And if you're dealing with the rest mode loop bug on LG OLED models, disabling just the Power Off Link setting on the PS5 is the targeted fix.

This guide covers every LG webOS version and every PS5 hardware revision - so you'll always find the right settings path for your specific model.
