Common Reasons Why Sony TVs Turn On By Themselves

Several factors can cause a Sony TV to turn on by itself. Here are the most common reasons and solutions.

Power Supply Issues

Power supply issues can often make a Sony TV turn on unexpectedly. First, plug the AC power cord directly into the TV and a wall outlet. This avoids interference from power strips or surge suppressors. Switching to a different AC wall outlet might also help determine if the outlet itself is causing the problem. A stable power connection minimizes the chances of the TV behaving erratically.

Remote Control Interference

Remote control interference is another common cause. Remove the batteries from the remote control to see if the issue continues. This helps identify if the remote is malfunctioning. Multi-function remotes should also be checked, as they can sometimes send unintended signals. Ensuring the remote is functioning properly helps eliminate one potential cause of the TV turning on by itself.

HDMI-CEC Settings

HDMI-CEC settings allow connected devices to control the TV. Disable the auto power on setting in BRAVIA Sync settings or HDMI CEC settings to prevent external devices from turning the TV on. Also, check connected devices like soundbars to see if they have auto-off features or timers that might trigger the TV. Adjusting these settings can stop the TV from turning on due to external device commands.

Troubleshooting Steps

If your Sony TV turns on by itself, follow these troubleshooting steps. These steps address common causes and can help resolve the issue effectively.

Checking Power Supply

First, check the power supply. Confirm the TV is getting a stable power source.

Power Reset:

Unplug the TV power cord from the electrical outlet.
Wait for 60 seconds.
Plug the power cord back into the outlet.
Turn on the TV.

Proper Power Cord Connection:

Ensure the power cord is firmly plugged into the TV and the wall outlet.
Remove any power strips or surge protectors and plug the TV directly into the wall outlet.

Inspecting Remote Controls

Next, inspect the remote controls. Issues with the remote can also cause the TV to turn on unexpectedly.

Remote Control Issue:

Remove the batteries from the remote and check if the issue persists.
If using a multi-function remote, check it as well.
Cover the remote control sensor on the TV to test if the issue occurs.

Adjusting TV Settings

Finally, adjust the TV settings. Incorrect settings may trigger the TV to turn on.

BRAVIA Sync Settings:

Go to Channels & Inputs → External inputs → BRAVIA Sync settings → BRAVIA Sync control → TV auto power on → Off.

These steps should help identify and resolve the issue of your Sony TV turning on by itself.

Advanced Solutions

Addressing the problem of Sony TVs turning on by themselves requires more advanced troubleshooting steps such as updating the firmware or performing a factory reset. These methods can help resolve underlying issues effectively.

Firmware Update

Keeping your TV’s firmware up-to-date is crucial. An outdated firmware can lead to unexpected behaviors.

Check for Firmware Updates: Ensure my TV runs the latest firmware. I navigate to Settings > System > About > System Update > Check for Update. This step will initiate an automatic search for the latest firmware version.
Update Firmware from USB: If the TV is offline, I download the latest firmware from Sony’s website. Using a USB drive, I transfer the update to my TV. This action helps address issues tied to outdated software. It requires:

formatted USB drive
downloaded firmware file
following on-screen installation prompts

Factory Reset

Factory resetting the TV can eliminate persistent software issues that cause it to turn on by itself.

Soft Reset: If my TV responds to the remote, I perform a soft reset by holding the POWER button until the TV restarts or a menu appears, then selecting Restart. This process reboots my TV without erasing settings.
Power Cycle: For a non-responsive TV, I unplug the power cord for 30 seconds and then plug it back in. This step helps resolve minor glitches by resetting the power supply.

By following these advanced solutions, I can effectively address the problem of my Sony TV turning on by itself.

Preventive Measures

Sony TVs may turn on by themselves due to various factors. Implementing specific preventive measures can help mitigate this issue.
