You shut it off, walk away, and somehow the screen lights up again a few minutes later. Or worse, you wake up in the middle of the night to find your living room glowing. This is one of the most common complaints from BRAVIA owners. Our research shows it almost always comes down to one of four causes: HDMI-CEC triggers, network wake commands, a stuck button on the remote, or an accidental timer. Sony's Bravia Sync feature, which uses the HDMI-CEC standard, is factory-enabled on most models sold since 2015. This lets your TV and connected devices power each other on when they sense activity. According to the HDMI Forum, CEC uses a single-wire control signal that travels across all HDMI ports. The convenience is great. But when something misfires, you get a ghost TV. Let's walk through why this happens and how to stop it. ![Sony Tv Turns On By Itself](https://gadgetguides.org/wp-content/uploads/2026/09/sony-tv-turns-on-by-itself-mtwmb6ov.webp) Image source: Bing (Web (fair-use with source credit)) ## The Quick Answer: What's Causing Your Sony TV to Power On By Itself The main cause is HDMI-CEC miscommunication. A connected device sends a power-on command. Your Sony TV obeys that signal by default. You can stop it by disabling Bravia Sync's "Device auto power on" option. Go to Settings > System > Power and Energy > Power-on behavior. Turn it off. ## Match the Symptom: The Sony Auto-On Decision Tree Not every ghost turn-on has the same root cause. The exact timing of the event tells you which fix is right. Use the branches below to match your symptom to the solution. ![Sony BRAVIA TV](https://gadgetguides.org/wp-content/uploads/2026/09/sony-bravia-tv-mtwmb8e5.webp) Image source: Bing (Web (fair-use with source credit)) ### Branch 1: Turns On Right After You Shut It Down Your TV powers back on within seconds of pressing the remote's power button. This is almost always a CEC conflict. A device like a soundbar or PlayStation is commanding the TV to wake. Try disabling CEC on that device first. If that fixes it, leave Bravia Sync enabled on the TV but turn off "Device auto power on." ### Branch 2: Turns On Randomly, Often at Night If the TV lights up at 2 AM with no one near it, the culprit is usually network standby or a voice assistant. A network wake packet from your router or a mistaken command from Google Assistant can trigger it. Disable "Power on by network" in the Power and Energy menu. Also check if a smart speaker is listening for "turn on the TV" and misfiring. ### Branch 3: Turns On When an HDMI Device Powers Up You plug in a streaming stick, or your gaming console starts, and the TV wakes. That is CEC's "One Touch Play" feature doing exactly what it was designed to do. Fix it by disabling "TV auto power on" within Bravia Sync settings on the TV. Some models also let you set each HDMI input to ignore CEC commands individually. ### Branch 4: Turns On After Power Flickers or Outages A brief power drop causes the TV to restart and come back on. Some BRAVIA models boot directly into the last state, which is "on." Use a surge protector that does not cut power abruptly. You can also enable "Power on status" to default to standby after a power loss. Check Settings > System > Power and Energy for this option. ## Fix 1: Disable Bravia Sync and HDMI-CEC Wake Triggers Bravia Sync is Sony's name for HDMI-CEC. It is the number one reason a Sony TV turns on by itself. The signal that lets your TV remote control your soundbar also lets that soundbar wake your TV. The fix is straightforward. On Sony TVs running Google TV (2021 and later), go to **Settings > System > Power and Energy > Power-on behavior**. Inside you will see two options: "TV auto power on" and "Device auto power on." Turn off "Device auto power on" first. That stops external HDMI gear from waking the TV. If you still see the problem, turn off "TV auto power on" too. On older Android TV models (2020 and earlier), navigate to **Settings > Bravia Sync > Device auto power on** and set it to Off. The menu path varies slightly by firmware version, but the target option is the same. If you prefer keeping CEC active for your soundbar, you can disable CEC on that specific device instead. Most soundbars and game consoles have a "CEC" or "HDMI control" toggle in their settings. That leaves Bravia Sync working for other devices while killing the ghost trigger. ![Bravia Sync](https://gadgetguides.org/wp-content/uploads/2026/09/bravia-sync-mtwmb9lr.webp) Image source: Web (Bing) / sony.com (Web image (fair-use with source credit)) For official guidance, Sony's support site maintains model-specific instructions for accessing Bravia Sync menus. Check [Sony Support](https://www.sony.com/electronics/support) and search your model number plus "Bravia Sync" for exact steps. ## Fix 2: Turn Off Network Standby and Voice Assistant Wake-Ups Your Sony TV can also wake up over your home network. This is great for casting and smart home control. But it also means any stray network packet or misheard voice command can turn the screen on. Our research shows this cause is especially common on Wi-Fi connected models with Google Assistant enabled. Go to **Settings > System > Power and Energy > Power-on by network** and set it to Off. The label may read "Remote start by network" on some firmware versions. Disabling this stops wake-on-LAN and wake-on-Wi-Fi commands from reaching the TV. Next, check your voice assistant integration. If you use Google Assistant or Amazon Alexa, review the routines that control the TV. A routine set to "turn on TV" at a certain time or when a motion sensor triggers can cause random start-ups. Disable those routines temporarily to test. Also turn off Bluetooth remote discovery if you do not use a voice remote. Go to **Settings > Remotes and Accessories > Bluetooth settings**. Unpair any remotes you are not using. A second remote stashed in a drawer can still send signals if its buttons are pressed. ## Fix 3: Check the Power On Timer, Remote, and Electrical Supply Before you blame software, rule out the simple stuff. A programmed timer, a stuck remote button, or a flickering power line can each make a Sony TV turn on by itself. Open **Settings > Device Preferences > Timers** or **Settings > System > Power and Energy > Timers** on newer models. Look for a Power On Timer that might be set for a specific time. Clear it if you find one. Also check Sleep Timer in case it is causing a false wake cycle. Remove the batteries from your TV remote for 24 hours. If the TV stops turning on by itself, the remote has a stuck power button. Replace the remote or clean the button contacts with rubbing alcohol and a cotton swab. Finally, inspect your power outlet. A loose connection or a surge can cause the TV to reboot. Plug the TV directly into a wall outlet, not a cheap power strip, and see if the problem stops. If you live in an area with frequent brownouts, a quality surge protector with voltage regulation is worth the investment. Sticky remote buttons are the second most common cause in our analysis, behind only CEC. Do not overlook this easy test before diving into deeper settings. ## The Full Reset Workflow: Step-by-Step Troubleshooting Sequence If the individual fixes above did not stop the ghost power-on, a full reset sequence usually catches any remaining cause. Follow these steps in order. Test the TV for 24 hours after each step before moving to the next. **Step 1: Power cycle the TV.** Unplug it from the wall outlet. Wait 60 seconds. Press and hold the power button on the TV itself, not the remote, for 30 seconds. This drains residual charge from the capacitors. Plug it back in and test. **Step 2: Disconnect all HDMI and USB devices.** Unplug every cable except the power cord. If the TV stops turning on by itself, reconnect devices one at a time over several hours. The device that triggers the problem is your culprit. **Step 3: Disable network connectivity.** Turn off Wi-Fi and unplug the Ethernet cable. If the problem stops, the cause was a network wake packet. Re-enable network features one at a time to identify the trigger. **Step 4: Perform a full factory reset.** This erases all settings, including any corrupted configuration data. Go to **Settings > System > About > Reset > Factory data reset**. You will need to set up the TV again from scratch. **Step 5: Update the TV firmware.** Sony releases firmware updates that address power management bugs. Go to **Settings > System > Software update > Check for update**. Install any available update and test for another 24 hours. ## Mistakes to Avoid That Make Sony TV Ghost Power-On Worse Some common DIY fixes actually make the problem harder to solve. Avoid these missteps to save yourself time and frustration. **Disabling HDMI-CEC on every device at once.** This removes the ability to isolate which device is sending the wake command. Instead, disable CEC on one device at a time and test between each change. You will find the specific trigger rather than losing all CEC convenience. **Using a universal remote with HDMI-CEC emulation.** Some universal remotes send their own CEC commands that conflict with Sony's implementation. If you introduced a new remote around the same time the problem started, remove its batteries and test with the Sony remote only. **Blindly unplugging the TV at night.** This prevents firmware updates and background maintenance from running. It also stresses the power supply over time. Use the settings fixes instead. They solve the root problem without forcing a nightly power cycle. **Ignoring a faulty wall outlet.** If your TV restarts after a power flicker, a loose outlet connection is dangerous. Call an electrician before you assume it is a TV software issue. A damaged outlet can cause intermittent resets that software settings cannot fix. **Skipping the remote battery test.** Many owners assume the remote is fine because it works for changing channels. A stuck button can be intermittent. Always remove the batteries for a full day as an early test. This takes zero effort and eliminates the second most common cause. **Rushing into a factory reset.** A factory reset is the nuclear option. It wipes all your settings, apps, and logins. Try the targeted fixes and power cycle first. A reset should be your last resort, not your first. ## Sony Auto-On FAQs: Quick Answers to Common Questions ### Why does my Sony TV turn on by itself in the middle of the night? The most common cause is network standby. A Wi-Fi signal, a voice assistant routine, or a router broadcast can wake the TV. Go to Settings > System > Power and Energy and disable "Power on by network." Also check for a Power On Timer under Settings > Device Preferences > Timers. ### Can a stuck remote button really cause this? Yes. A button pressed under a cushion or by a pet sends a constant signal. The TV interprets this as a command to power on. Remove the batteries for 24 hours to test. If the problem stops, replace the remote or clean the power button contacts. ### Will disabling Bravia Sync break my soundbar? Not necessarily. Bravia Sync controls power and volume over HDMI-CEC. If you only need volume control, keep "TV auto power on" enabled but turn off "Device auto power on." Your soundbar will still respond to the TV remote, but it will not wake the TV unexpectedly. ### Should I buy a new TV if this keeps happening? Almost never. The fix is almost always a settings change, a remote issue, or a firmware update. Only consider a replacement if the TV has physical damage, a known main board failure on your exact model, or Sony support confirms a hardware defect. ### How do I find the exact menu path for my model? Sony's support site lets you enter your model number for model-specific instructions. Look for the label on the back of the TV or in Settings > System > About. The menu names vary between Android TV and Google TV versions, but the relevant options are always under Power and Energy or Bravia Sync. ### What if none of these fixes work? Contact Sony support directly. Ask about a known issue for your model number. Some older BRAVIA models have documented main board faults that cause phantom power-on. If your TV is out of warranty, compare the cost of a main board replacement against a new TV before committing.
