TV is Philips, Model No.: 50PFL3008H/12
When I turn my TV on I get sound and picture no problem. However after about 10 minutes the picture disappears. When I shine a flashlight on the screen I can see silhouettes. I don’t understand why does it happen after some time of running. Any Idea? What also worries me is the power board. I can hear quite annoying high-pitch buzzing and right above it there is a black ‘trail’ from heat, I assume. This is my first open TV so I have no idea if it’s normal or not.
What I would like to find out is how do I determine what is the issue causing the picture to disappear and is the power board ok? Thanks
Replace the board unless you have some circuit board repair experience. Here’s one possible source: https://www.televizyonkarti.net/171ps20p… Schematics: https://electronicshelponline.blogspot.c… Most of the searches bring up the Vestel 171ps20 but not the Vestel 171ps20p. “P” for Philips?
