If your Sony TV keeps turning on by itself, there may be an issue with its power supply. To fix this, make sure all cables are plugged in securely and there are no loose wires present.
To confirm if your wall socket is providing enough electricity, plug another device into it. It should draw around the same amount of current as your TV to ensure there isn’t an issue with your household electricity supply.
Check the Power Cord
The power cord is the main connection between your TV and wall outlet, so make sure it’s securely plugged in and not frayed or damaged. Furthermore, using grounded power cords can help prevent fires by providing extra insulation between them and the outlet.
If you notice any damage or fraying in the cord, it may be time for a replacement. Alternatively, you could unplug your TV from its outlet and plug it into another socket.
This is an effective way to pinpoint any potential issues and determine their source. Additionally, it gives you a chance to inspect around your television to check for anything else that could be contributing to the issue.
Next, unplug the TV from its wall outlet and wait a few minutes to see if it starts turning on again. This will provide an indication of whether there is an issue with either its cable or outlet itself.
Additionally, you should remove the bezel, panel and TV backlight to inspect for any loose connections or broken wires. There will be three main boards underneath – T-Con board (identified by its obvious power connectors), Power board and Backlight Board (also known as CEC board).
It is essential that you handle these boards with caution and precision. Don’t pull on them until you are certain they are secure, and avoid touching them with fingers or any metallic objects which could scratch them.
Once the boards have been taken off, you can test them with a voltmeter or TV backlight tester for failures. If any do not function properly, replace them immediately.
If your Sony television turns on by itself after some period of inactivity, replacing the power cord might not be necessary. To resolve this problem, plugging the power cord back in and holding down the power button until a white LED light appears on-screen will reboot your device.
Check the Remote Control
If your Sony TV turns on by itself, it can waste electricity, damage its internal components and even pose a fire hazard. If this occurs to you, there are steps you can take to remediate the situation.
First and foremost, check your remote control. It could have a stuck power button or low batteries, sending random signals to your TV that could turn it on by mistake. In such cases, unplug the television and press the power button on the remote to see if that solves the issue.
Next, disconnect any other devices or applications connected to the TV. These could include USB devices, HDMI devices, LAN connections and antennas.
It’s essential to disconnect all Wi-Fi-connected devices, such as streaming sticks and gaming consoles, before your Sony TV can automatically turn on. Doing this prevents the TV from turning on by itself unexpectedly.
Another option is to update the firmware on your Sony TV. Doing so will fix any bugs in the software and guarantee that your television continues working optimally.
You can stop your TV from turning on automatically by disabling certain settings in the Sony BRAVIA settings menu. Here, you will disable BRAVIA Sync and other options that could be causing it to do so automatically.
If this doesn’t solve the problem, you may need to replace the remote. You can search online or at your local electronics store for a replacement remote.
In most cases, this is a straightforward process that takes less than two minutes to complete. If it doesn’t work for you, Sony customer support is available for further assistance or to arrange for an experienced technician to come out and repair your TV on site.
If your TV still turns on by itself after you have removed all external devices and updated the firmware, there could be an issue with its power supply. Although this is a rare occurrence, it’s worth checking to see if there is one. If so, have a technician inspect the power supply to see if there is a faulty cable present.
Check the Timer
Sony TVs that turn on by themselves may have several causes, such as a malfunctioning remote control, power surges, timer function, firmware bugs, power settings on connected devices and sensors that aren’t functioning correctly. To diagnose the problem you’ll need to check all power cords and outlets; replace batteries in remote controls; factory reset the television; and review its settings.
First, make sure there are no bugs in the firmware of your TV. If there are, installing updated firmware updates should solve the issue.
If you own a Sony TV with a smart home system, it’s worth double-checking that none of its components are sending “wake up” signals to your television without asking. Old Roku devices, gaming consoles and other non-updated items can all send signals to your television that make it turn on automatically regardless of what you’re watching.
You can disable HDMI Consumer Electronics Control (CEC), which prevents HDMI-connected devices from turning your TV on by default. To do this, access the Bravia Sync settings on your remote and turn them all off.
Sony TVs often come equipped with a sleep timer, which will automatically switch the television off after a predetermined amount of time. This handy feature helps conserve energy and extends your television’s lifespan.
Another common cause of Sony TVs that turn on by themselves is an aging or defective set of components inside. If this is the case, you may need to replace those parts or purchase a brand-new television set.
Sony TVs occasionally experience random shut offs and cannot be turned back on, which can be an irritating issue to deal with.
If your soundbar or other device has the BRAVIA(tm) Sync (HDMI-CEC, ARC, or eARC) feature, you can disable auto-off by going into your mobile app “BOSE SOUNDTOUCH,” disabling that feature and saving.
Check the Firmware
If your Sony TV is starting to turn on by itself, it might be time for a factory reset. This will clear all settings and eliminate any previous bugs or glitches that were causing the problem. If this does not solve it, contact Sony support for further assistance.
One of the most frequent reasons a TV may turn on by itself is due to a firmware issue. Fortunately, this issue is easily remedied.
To check the firmware of your TV, open the XMB menu on your remote and look for System Information. Afterwards, click the Update Now button to download any available updates.
Once you’ve identified the latest software for your Sony TV, it’s easy to update it to ensure you have all of the most up-to-date features and fixes, plus that your television won’t keep crashing in the future.
Before you do this, however, it’s wise to ensure your firmware is up-to-date. Some smart TVs come with an automated update feature which downloads updates automatically; alternatively, you can manually upgrade your TV as well.
Another possible explanation for why your TV may be turning on by itself is due to stray signals from other devices connected to your home network. If this is the case, you can disable CEC (Controlled Excitation Command) on your television so that it does not activate any additional devices.
Furthermore, if your television has a timer, it might be turning on by itself if you haven’t set it to turn off again after some period of time. To resolve this problem, go to Settings > Preferences and disable the timer.
If the above troubleshooting steps have not resolved the problem, you can try replacing the power button on your TV. This should eliminate any defective buttons and should resolve the problem.
Before you attempt to troubleshoot a Sony television that turns on by itself, it’s essential to know its model number. This will enable you to locate manuals and customer support from the manufacturer so that you have all of the information necessary for getting your Sony TV up and running smoothly.
