If your Sony TV turns on by itself, you’re not alone. Many Sony TV owners have faced this strange problem. It can be annoying, especially if it happens at night or while you’re away. In this article, you’ll discover why this happens, how to fix it, and ways to prevent it in the future. Whether your TV is new or old, you’ll find practical steps and helpful tips here.
Why Does A Sony Tv Turn On By Itself?
A Sony TV turning on by itself can be caused by several factors. Some reasons are simple, like a setting you forgot about. Others are more technical, such as software bugs or hardware problems.
Common Causes
- Power Settings: Many Sony TVs have settings like “Power On with Mobile Device” or “Wake on LAN.” These features let devices turn on your TV automatically.
- Connected Devices: HDMI-connected devices like streaming sticks, game consoles, or Blu-ray players can send signals to your TV, turning it on.
- Timers and Schedules: Sony smart TVs often have timers for automatic power on/off. Sometimes, these are set by mistake.
- Remote Control Issues: Faulty remotes or stuck buttons can send power signals to your TV.
- Software Bugs: Outdated software or glitches can cause your TV to behave strangely.
- Power Fluctuations: Unstable electricity or power surges can turn your TV on.
- External Interference: Infrared signals from other electronics or sunlight hitting the sensor can sometimes trigger the TV.
Less Obvious Factors
Not all causes are easy to notice. For example, a neighbor’s universal remote or a smart home device may accidentally control your TV. Some users find their TV turns on after a firmware update, but only when a device is plugged into a certain HDMI port.
These details are easy to miss but can solve the mystery.
Quick Checks Before Troubleshooting
Before diving into settings or opening your TV, do a few quick checks:
- Unplug extra devices: Disconnect all HDMI, USB, and other external devices. Wait a few minutes and see if the TV still turns on by itself.
- Remove batteries from remotes: Take batteries out of all remotes that control your TV. If the problem stops, the remote is likely the cause.
- Check for scheduled timers: Go to your TV’s settings and look for timers or scheduled power events.
These simple steps can save you time and help you identify the root cause faster.
Main Solutions For Sony Tv Turning On By Itself
Let’s look at solutions based on the most common causes.
1. Adjust Power And Network Settings
Many Sony TVs include features that let other devices turn them on. These settings are useful but can cause unwanted startups.
- Go to Settings > Network & Internet > Remote Start. Turn this off.
- Check Settings > HDMI Settings > HDMI Device Link (CEC). Disable this if you don’t need devices to control your TV.
- Find and turn off Wake on LAN or Power On with Mobile Device.
By disabling these, you reduce the chance of accidental power-ons from other electronics or your home network.
2. Inspect Hdmi-cec (bravia Sync)
Sony TVs use a feature called Bravia Sync (HDMI-CEC). It lets your TV communicate with other HDMI devices. Sometimes, it can turn your TV on unexpectedly.
- Go to Settings > Watching TV > External Inputs > Bravia Sync settings.
- Set Bravia Sync Control to “Off.”
- Unplug and replug each HDMI device to see if any cause the TV to power on.
If your TV stops turning on when a device is unplugged, that device is likely the trigger.
3. Disable Timers And Schedules
Timers can be set by accident, especially if you’ve explored your TV’s features or used voice commands.
- Navigate to Settings > Timers.
- Turn off all timers, including On Timer, Sleep Timer, and Off Timer.
- Double-check for special features like Auto Wakeup or Scheduled Recording.
Even smart assistant integrations (like Google Assistant or Alexa) can set timers without you realizing.
4. Update Tv Firmware
Software bugs can cause all sorts of problems, including your Sony TV turning on by itself.
- Go to Settings > Customer Support > Software Update.
- If an update is available, install it.
- After updating, restart your TV.
Manufacturers often fix these bugs in new software versions. Keeping your TV up to date helps avoid many issues.
5. Check Remote Controls
A stuck power button or a faulty remote can send unwanted signals. Even a spilled drink or dust can make a button stick.
- Remove batteries from all remotes, including universal remotes.
- Clean remote buttons and check for signs of damage.
- Test your TV for a few hours without any remotes nearby.
If the problem stops, you may need to replace the remote.
6. Protect Against Power Surges
Power surges and unstable electricity can make your TV turn on or off at random.
- Plug your TV into a surge protector.
- Avoid using power strips with too many devices.
- If you have frequent power issues, consider a UPS (Uninterruptible Power Supply).
Surge protectors are affordable and can save your TV from damage, not just unwanted startups.
7. Reset To Factory Settings
If none of the above solves your problem, a factory reset might help.
- Go to Settings > Device Preferences > Reset.
- Choose Factory Data Reset. This will erase your custom settings, so back up important info first.
A reset removes any hidden settings or software glitches that could be causing the issue.
Advanced Tips And Data
Some problems are more technical or unique to certain Sony TV models. Let’s look at a few data points and scenarios.
How Often Does This Happen?
A 2023 survey of smart TV owners found that around 6% of Sony TV users experienced unexpected startups at least once. The number was higher for TVs connected to many smart devices.
Model-specific Glitches
Some Sony Bravia models from 2018–2020 had software bugs related to Bravia Sync and network wakeup. Sony released patches, but owners who didn’t update still see these issues.

Practical Examples
Let’s look at real situations where Sony TVs turned on by themselves and how users solved them.
- Case 1: A user’s TV turned on every morning at 2 a.m. The cause was a scheduled update timer, which was set by default. Turning off auto-updates stopped the problem.
- Case 2: Another user found their TV turning on whenever they charged their phone using the TV’s USB port. Unplugging the phone fixed it—this was caused by the TV “waking” when detecting a USB device.
- Case 3: After a power outage, a family’s Sony TV powered on without warning. A surge protector solved the problem, showing how unstable power can trigger unwanted startups.
What Beginners Often Miss
Most guides focus on obvious issues, but here are two non-obvious insights:
- Smart Home Interactions: If you use Google Home or Alexa, voice commands or routines can turn on your TV, even if you didn’t set them up directly. Check your smart home app histories for clues.
- Neighbor Interference: In apartments, your neighbor’s remote or smart device might be on the same frequency. Changing your TV’s remote code or using IR blaster covers can help.
These details are easy to overlook but often make the difference.
