Why does my Panasonic TC-P42X1 tv not turn on.
My tv will only turn on if I hold the power button for 3 seconds and then push it again. It doesn’t always work. Sometimes I repeat the process for up to 10 minutes before it will turn on. Then it works fine until it shuts off again.
"Linda Dirks appears to be a power board issue. You do want to go ahead and remove the back from your TV. (unplugged of course) and take a look at the boards. Check for any burned or otherwise damaged looking component.
Post some good pictures of your boards with your question so that we can see what you see. Adding images to an existing question
You will need a multimeter so that you can eventually get to the point of checking a few things."
