There is some component(s) on one of the boards that is causing too high a current pull, or the power supply itself is failing. This has to be verified by the tech. He will do board substitution to locate the bad circuit board.

Tv come on then shuts off


Does the power light blink after it shuts down? The number of blinks will usually indicate which area is failing. Most plasma tv's fail due to YSUS and Y buffer board failures.

A component in the TV is failing and is not receiving correct voltage, which is causing the TV to enter " protection mode" and shut off. Could be any part of the TV but I would start with the power supply and go from there.

Here is some basic info on testing the power supply.

I have a panasonic plasma tv. Model #


I don't know but I'm having a similar problem. I have a plasma
TH-50PZ77U. It will run for a while and then shuts off. Also, the volume goes up and up and then it shuts off at times. Like I have a ghost here. I had both of my sat. recievers replaced. It seems to get worse over time with shut down. I called panasonic and they had no info and denied this was an issue but I beg to differ from my research here online. It's only a few years and we paid lots of $$$. They gave me a # for service 1 hour away!
