Sony TV Randomly Shuts Off: Troubleshooting and Solutions

My Sony TV has been acting up lately, randomly turning itself off without warning. At first, it was just a minor annoyance, but now it’s happening more and more frequently, and I’m starting to lose patience. So, I decided to take matters into my own hands and troubleshoot the issue.

After extensive research and testing, I’ve managed to identify the culprit and found a solution that has worked for me. In this article, I’ll share my experience and provide a step-by-step guide to help you diagnose and fix the problem when your Sony TV randomly shuts off.

Possible Causes and Solutions

There are several potential causes for a Sony TV to randomly turn off:

Outdated Firmware

One of the most common causes of this issue is outdated firmware. As new features and bug fixes are released, it’s essential to update your TV’s firmware regularly. To do this, go to the TV’s settings, select “System,” and then “Software Update.” If an update is available, download and install it. Wait for the process to be completed, and your TV should reboot normally.

Faulty Power Supply

Another possible cause is a faulty power supply. The power supply unit (PSU) is responsible for providing power to the TV’s components. If the PSU is malfunctioning, it can cause the TV to suddenly shut off. To check if the PSU is the issue, unplug the TV from the power outlet and wait a few minutes. Then, plug the TV back in and turn it on. If the TV stays on, the PSU is likely not the problem. If the TV still turns off randomly, you’ll need to contact Sony support or a qualified technician to replace the PSU.


Excessive heat can also cause a Sony TV to shut off randomly. Make sure your TV has proper ventilation and is not enclosed in a cabinet or other enclosed space. You can also try reducing the TV’s brightness settings, as a brighter screen generates more heat. Clean dust from TV vents and avoid placing the TV near heat sources.

HDMI Connection Issues

Loose or faulty HDMI cables can cause the TV to receive intermittent signals, which can lead to random shutdowns. Check the HDMI cables connecting the TV to other devices and ensure they are securely plugged in. If possible, try using different HDMI cables to rule out any cable-related issues.

Software Bugs

Sometimes, software bugs can also cause the TV to behave erratically. To fix this, perform a factory reset on the TV. This will erase all settings and data, so be sure to back up any important data before proceeding. To perform a factory reset, go to the TV’s settings, select “System,” and then “Factory Data Reset.”

Expert Tips and Advice

Here are a few additional tips and advice from experts:

  • Disable the “Quick Start” feature. While this feature can speed up boot times, it can also increase power consumption and potentially lead to random shutdowns.
  • Update the software of all connected devices, such as streaming sticks, gaming consoles, and Blu-ray players. Outdated software can sometimes conflict with the TV’s firmware, causing stability issues.
  • If the TV is still under warranty, contact Sony support. They may be able to provide additional troubleshooting steps or arrange for a repair or replacement.
