Looking for help please. My LG plasma tv(60PK540-UE) will turn on but after about 20 to 30 min will shut off. You can turn it back on but it eventually get to the point where when you hit the power button, itll click and turn on then shortly after(couple seconds, itll click again and turn off. Could it be the power supply? Any help is appreciated. Thank you.

Hi @clriii ,
It seems as though something is heating up and then failing, shutting the TV down.
Here’s the Power Up -boot fail, troubleshooting guide from the service manual, which may be a good place to start when it fails to start and stay on.
It is possible to use the manual online but it is awkward, as you have to change the page number below the document for every page to go to the next page. To download it you need to register with the website.
Hopefully a start.
