Hi, I have a Seiki SE42UMT that don't power on anymore.
The standby red LED will stay lit but nothing else.
I can hear a constant high pitched sound from the power supply board.
I already have replaced the power supply but the problem still persist so, we can rule out that the power supply board is good.
I also inspected visually every boards and I can't see anything that could have burnt or blown capacitors.
Here are attached few pictures of the 3 boards.
Thank you !
