Title: Help Pls! Replacement power supply board/Magnavox LED TV didn't work, no power
Post by: Tricia0723 on May 19, 2018, 11:25:39 am

Good Day! I thought replacing the power supply board on my Magnavox LED TV would solve the No Power problem. My red standby light does come one. But after replacing the board, I still have the same problem. The set is about 5 years old. I double checked that I received the correct replacement part by matching the part numbers. Can anyone help? Thanks so much!  I posted a similar message on the Repair Board, but while I got about 20 reads, no replies yet. Guess I shouldn't have posted there. Oh well....  Thanks again.

I would look at the main processor reset line, check if there is a power good IC on reset and confirm reset is going high

Thanks for your advice, but I'm not skilled in this area. Is the main processor part of the power supply board? I'm not sure what IC means. I don't have electrical tools. I understand if you can't help further. Thanks again!
