Hello I have a Phillips TV that won't turn on, and when you plug it in it makes a high pitch humming noise from the power supply board.
I've been reading online, it could be caused by bad capacitors but I'm not sure which ones. Or if it could be something else.
Does anyone have some troubleshooting steps I could perform to help isolate the issue.
I don't see any physical issue/burnt items on the board.
Thanks for your help.
Chris...
