I purchased a PN64F8500 used with an issue where it would not turn on and replaced three caps on the Y-Board and it was fixed and been working ever since.
Few months later I see a PN60F8500 for sale on CL with a note saying it does not work, so figure the same easy fix and I'll have a new TV.
The issue is slightly different, the TV will power on but after around 5 minutes or so it will power itself off and not turn back on.
After opening up the back I notice the boards are completely different and those three caps from the 64 inch do not even exist on the 60 inch model.
I have looked on various forums online and seems that this is an issue with the power board itself. The board is model BN44-00602A. I have replaced the main 4 large capacitors but still have same issue. Has anyone else had this issue? I have also read it is possible it is chopper transistor failing short circuit or the bridge rectifier failing short circuit. I am not even really sure what those components are. Is there a way to easily check the remaining caps on the power board to single out any that may be damaged?
