If your Sony TV won’t turn off and keeps running after you try to power down, it’s usually caused by a stuck remote button, an active HDMI-CEC device, or a temporary system glitch. Settings or firmware can also keep the TV from responding normally to the power command. Calmly work through the fixes below to get the TV powering off as expected.
If your Sony TV won’t turn off, do a power reset first: unplug the TV from the wall, wait a short moment, then plug it back in. If it’s still stuck on, check for remote/physical button issues and settings like HDMI-CEC/BRAVIA Sync that can keep the TV “awake.” This guide walks you through the most reliable fixes in order, from quickest to deeper resets.
This applies when your Sony TV stays on (or won’t enter standby) even after pressing Power. It’s also common after a firmware update, a new device (game console/streamer) connected via HDMI, or if a remote/battery issue causes repeated wake signals.
Power reset (fastest fix)
A power reset is usually the quickest way to fix a Sony TV that won’t turn off because it forces the TV’s internal software and power controller to reboot cleanly. When a TV “hangs” in a busy state, the Power button may appear to work—but standby never completes.
Start with the simplest step first:
– Unplug the TV from the wall power for a brief pause, then plug it back in and try turning it off again.
– If your TV has a standby light, watch for a change in behavior after re-plugging (that often indicates the set rebooted).
Why this works: modern Sony BRAVIA TVs keep background processes running (apps, HDMI-CEC handshake, and sometimes network services). A power reset clears stuck signals, soft-locks, and partial updates that can leave the TV “ready” but not fully transitioning into standby.
Also, avoid rushing the cycle. Give the TV a moment after re-plugging (even if the screen comes back quickly) before you press Power again. In my troubleshooting notes, I’ve seen repeated “off” presses right after power restore increase the chance of a “won’t enter standby” loop—so the pause matters.
Check the remote and the TV’s physical buttons
If your Sony TV won’t turn off, a remote or button problem can be just as likely as a TV software issue. A stuck button can continuously send wake/off-related commands, making it look like the TV ignores Power.
Do these checks in order:
– Make sure the remote’s power button isn’t sticking (try a different button first, and replace batteries if needed).
– Inspect the TV’s own power button: if it’s jammed or repeatedly pressed, the TV may ignore off commands.
What to look for:
– Remote issues: weak batteries can cause erratic IR/BT behavior. Also check for physical damage (cracks near the power key) and any debris under the button.
– Physical button issues: dust, a dropped TV, or wear can make the power switch bounce. If the TV seems to react when you lightly touch the area near the button, stop pressing Power and troubleshoot the button first.
Quick test: if you can turn the TV off using an alternate method (for example, a different remote, or the TV’s own menu power control if available), the issue is likely in the specific command source—Sony TV remotes and button assemblies are common failure points.
Disconnect HDMI devices and disable “wake” triggers
A Sony TV that won’t turn off is often staying “awake” because a connected HDMI device is signaling it to remain on or wake it up. HDMI-CEC (Consumer Electronics Control) is designed for seamless control between devices, but it can also cause unwanted wake-and-standby loops—especially after a firmware update or when you connect a new console or streaming box.
Try this sequence:
– Unplug external devices one by one (HDMI streaming box, game console, Blu-ray player) and test whether the TV can turn off.
– If your model supports it, review BRAVIA Sync / HDMI-CEC settings (a connected device can sometimes signal the TV to stay on).
A practical “one-device” method:
1. Turn the Sony TV on.
2. Disconnect all HDMI devices except power.
3. Press Power to confirm the TV can enter standby.
4. Reconnect devices one at a time, each time checking if the TV refuses to stay off.
Common trigger patterns:
– Game consoles: waking from controller input can immediately re-activate the TV.
– Streaming boxes: “auto play” or scheduled network activity can reassert HDMI-CEC control.
– Soundbars/AV receivers: if the TV thinks it’s part of a system, it may keep itself active to route audio.
BRAVIA Sync / HDMI-CEC: quick comparison for decision-making
If you’re deciding whether to disable CEC/sync, use this trade-off view.
| Option | Best when | Trade-off |
|---|---|---|
| Disable HDMI-CEC on the TV (or turn off BRAVIA Sync) | You need reliable standby/off first | You may lose “one remote controls other devices” features |
| Disable CEC on the HDMI device instead | You want the TV to control other gear less | Device may behave normally, but setup complexity can remain |
| Keep CEC enabled, but test device-by-device | You want minimal disruption | Takes longer; the culprit device may still re-trigger after a reboot |
Adjust power-saving / sleep-related settings
If your Sony TV won’t turn off, power-saving and sleep automation can be keeping the TV in an “active” state even when you press Power. As of 2026, many TVs also use network-connected behaviors (updates, standby services, and device discovery) that can override basic sleep intentions.
What to check:
– Look for settings like Power Saving, Auto Shut Off, or Sleep Timer and confirm they aren’t conflicting with the behavior you’re seeing.
– If the TV won’t respond consistently, temporarily disable any automation features that could be keeping it active (naming varies by model).
Why this matters: standby and off-mode behavior is constrained by energy standards, so TVs often balance “quick wake” with low power. According to U.S. EPA ENERGY STAR (Standby power guidance), standby power can account for a meaningful share of electricity use in households, which is why manufacturers implement aggressive power modes—sometimes alongside network features that can still trigger activity.
At a technical level, the TV may:
– Keep HDMI handshake active (especially with HDMI-CEC enabled)
– Maintain a network session briefly after input changes
– Run scheduled tasks after a firmware update
A simple reality check using standby-power benchmarks
Even though these benchmarks don’t “force” a Sony TV to stay on, they explain why power modes are nuanced.
Standby/Off Power Limits for TVs (Representative Benchmarks)
| # | Program / Regulation | Standby Max | Off Max | How this affects “won’t turn off” |
|---|---|---|---|---|
| 1 | Energy Star (TVs—standby/off benchmarks) | ≤ 0.5 W | ≤ 0.5 W | High relief ★★★★★ |
| 2 | EU ErP (standby/off power limits) | ≤ 0.5 W | ≤ 0.3 W | High relief ★★★★☆ |
| 3 | California Title 20 (standby/off requirements) | ≤ 0.5 W | ≤ 0.5 W | Moderate relief ★★★★☆ |
| 4 | Australia MEPS (TV standby/off benchmarks) | ≤ 0.5 W | ≤ 0.3 W | Moderate relief ★★★☆☆ |
| 5 | UK energy efficiency benchmarks (standby/off) | ≤ 0.5 W | ≤ 0.3 W | Moderate relief ★★★☆☆ |
| 6 | China energy labeling (TV standby/off limits) | ≤ 0.5 W | ≤ 0.3 W | Moderate relief ★★★☆☆ |
| 7 | Japan Top Runner (TV low-power benchmarks) | Varies by class | Varies by class | Context-dependent ★★☆☆☆ |
Note: These benchmarks are representative and can vary by TV class, year, and measurement method. For a specific Sony TV, the more actionable fix is still to disable wake triggers (HDMI-CEC/BRAVIA Sync) and confirm your Sleep Timer/Auto Shut Off settings.
Update or reset the TV (deeper troubleshooting)
If your Sony TV still won’t turn off after power reset and HDMI/remote checks, the most likely cause is a software glitch—often triggered by a firmware update or a corrupted settings state. At this stage, you should update first (if available) and only then reset.
Proceed in this order:
– Check whether there’s a firmware update available in the TV’s settings; software glitches can cause “won’t turn off” behavior.
– If nothing else works, perform a factory reset (or “reset settings” if offered), then test power control again.
– Note: this may remove app logins and configuration—only do it if you’re okay restarting setup.
Before you reset, record what you’ve already changed:
– Were HDMI devices disconnected when you tested standby?
– Did disabling BRAVIA Sync stop the loop temporarily?
– Does the TV still refuse standby even with everything unplugged (including HDMI sources)?
Factory reset trade-off (so you don’t get surprised):
– Pros: clears corrupted configuration and many edge-case software states.
– Cons: takes time, requires re-login, and can undo accessibility/network preferences.
Also, if your Sony TV “turns off briefly and returns immediately,” that’s a strong sign the issue is still being driven by an external wake trigger (HDMI-CEC) or an automation feature—resetting without fixing wake causes often wastes time.
Stop conditions for safety
If the TV shows power-related damage signals (sparks, unusual heat, burning smell), stop troubleshooting and get professional service rather than repeatedly power-cycling.
What can go wrong (and when to stop)
Even with the best troubleshooting steps, Sony TVs can behave unexpectedly due to multiple overlapping systems (CEC, network standby, and local wake triggers). If your fixes aren’t producing progress, you need to change approach instead of escalating the same action.
Watch for these edge cases:
– If the screen stays on but you hear no input change, it might not be “stuck on” so much as “not switching modes”—retest after disconnecting HDMI devices.
– Avoid repeated unplug/plug cycles too quickly; give the TV a little time between attempts.
– If the TV turns off briefly and returns by itself immediately, the cause is often an external HDMI/CEC device or a stuck wake signal—focus on those first.
– Stop and get help if you notice unusual sounds, a burning smell, or visible damage to the power cable or port.
A small but important point: pressing Power repeatedly can sometimes “queue” behavior. If you just changed a setting (like turning off BRAVIA Sync), wait for a full reboot and then test standby once.
Verdict / tip (what I’d try first)
Start with the power reset and HDMI device removal, because those resolve most “won’t turn off” issues without risking your settings. Only move to a full factory reset if the TV still can’t enter standby, since it’s disruptive—and skip it if you need the TV configured the same day.

Frequently Asked Questions
What should I do first if my Sony TV won’t turn off using the power button?
First, try holding the TV’s power button on the remote or the TV itself for 5–10 seconds to force a restart. If the screen still won’t power down, unplug the Sony TV from the wall for 60 seconds, then plug it back in and test the power button again. This clears temporary power or software states that can prevent a TV from shutting off.
How can I fix a Sony TV that won’t turn off after a firmware update or software glitch?
Restart the TV by unplugging it for 60 seconds, then check for any pending Sony firmware updates in Settings. If the issue continues, perform a factory reset from the TV menu (only after backing up settings if possible), since a corrupted software state can block normal shutdown. After resetting, test whether the Sony TV can turn off normally using both the remote and the TV power button.
Why does my Sony TV stay on when I press power, even though I’m using the correct remote?
This can happen if the remote isn’t sending a proper shutdown command or if HDMI-CEC devices are triggering the TV to wake back up. Disconnect external devices temporarily (soundbar, game console, streaming box) and disable HDMI-CEC/BRAVIA Sync in Settings, then try turning the TV off again. If the TV shuts down properly with devices disconnected, the culprit is usually an external component or a CEC setting.
Which settings should I check if my Sony TV won’t turn off but only goes to “sleep” or “standby”?
Review the Power & Energy or Eco settings for options like “Auto Shut Off,” “Sleep Timer,” and “BRAVIA Sync” behavior. Also check whether Motion/Presence detection or network features are keeping the TV active, especially on Android TV/Google TV models. Toggling off “Wake on LAN” (if available) and disabling wake-related features can help ensure your Sony TV actually turns off when you request it.
What is the best method to power-cycle a Sony TV that won’t turn off, and when should I contact support?
The best approach is a full power cycle: unplug the TV from the wall, wait at least 60 seconds, then reconnect and power it on before testing shutdown again. If the Sony TV still won’t turn off after repeated resets, check for stuck buttons on the TV (dust or physical obstruction near the power key) and try a different remote. If none of these fixes work, the issue may be hardware-related (power board or control circuitry), so contact Sony support or a qualified technician.
