How to resolve Westinghouse Smart TV Power Turning Off Sporadically ?


1. Turn off the Sleep Timer

The sleep timer turns off the television after a predetermined amount of time. Turning off the sleep timer should solve the issue.

Luckily, it's easy to turn off the sleep timer on a Westinghouse Smart TV. 

Here's how to do it:

  • Press and hold the Home button on your remote for 5 seconds.
  • A special menu will open, select Sleep.
  • Make sure the sleep timer is disabled.


That's it! Your Westinghouse Smart TV should now be set to never turn itself off due to the sleep timer. 


If your TV continues to turn off sporadically, you may have an issue with the power supply or internal components. 


2. Perform a Power Management Check
  • One of the first things you should do before attempting to perform power management checks on your Westinghouse Smart TV is to make sure the physical connections to your TV are secure. 
  • Make sure that all of the cables and cords connecting your TV to the power source are firmly attached. 
  • Check the wall outlet or surge protector to make sure it is properly wired and the power switch is turned on. 
  • If everything looks good on the physical side, it is time to move on to the next step.
  • Now to perform the power management checks on your Westinghouse Smart TV, simply open the Westinghouse TV Settings Menu. 
  • Once you have reached the settings menu, navigate to the 'Power Management' section and check to make sure that all of the settings are set to their factory defaults. 
  • Checking these settings will ensure your Westinghouse Smart TV is not attempting to turn itself off due to power savings features.


3. Check the power cable connections
  • Loose power connections are a common cause for TVs turning off by themselves. 
  • Ensure that the power cable is securely plugged into both the wall outlet and the TV. 
  • Also check if the wall outlet itself is loose. 
  • It's a good idea to try another wall outlet to rule out any issues with the current outlet.


4. Disable energy saving options
  • Most Westinghouse Smart TVs come with energy saving options enabled by default that may turn off the TV after a period of inactivity to save energy. 
  • Go to the Settings menu on your TV and turn off any energy saving or auto power off options. 
  • Also turn off the option to turn off the TV if no signal is detected.


5. Update the firmware
  • Outdated firmware on your TV can sometimes cause power issues. 
  • Open the Settings menu and check if any software updates are available for your TV. 
  • If so, install the latest update which may fix any software bugs that are causing the TV to shut off by itself.


5. Check for overheating issues
  • Overheating can cause a TV to suddenly turn off as a safety precaution. 
  • Make sure there is good airflow around your TV and no objects blocking the vents. 
  • Allow the TV to cool down for a few hours. 
  • Also try eliminating any heat sources near the TV. 
  • If the issue continues, you may need to service the TV to repair any damaged components.


6. Perform Factory Reset on the TV
  • As a last resort, you can try resetting your Westinghouse Smart TV to factory settings. 
  • Go to the Settings menu and select "Reset to Factory Defaults". 
  • Make sure you have any login or streaming service information handy to sign in again. 
  • A reset may resolve any software issues and fix the problem of the TV turning off randomly.


In fact, there are a few common reasons why a Westinghouse Smart TV may keep turning off by itself, including loose cable connections, incorrect power settings, outdated software, overheating issues or other software glitches. With some basic troubleshooting, you may be able to fix the problem without needing technical assistance.


Go through the steps outlined above to ensure your TV's power cable is secure, disable any auto power-off features, update your TV's firmware, check for overheating, and reset your TV to factory settings. After following these solutions, your Westinghouse TV should stop turning off sporadically and function normally again so you can get back to streaming your favorite content without problems.
