Re: Magnavox 40me313v/f7 tv PSU

I fixed my 40ME313V/F7 when the transormer started making a chirping, screeching noise after being powered on. Pulled the flex cable from the Digital Main Board (BA3ATZG0401) and the power supply was happy. I removed the Digital board and supplied 21vdc from a variable power supply outputing a few amps and while using a FLIR TG267 found that C3622 had a dead short to ground. Took longer to find a replacement cap then it was to find the problem. I don't think I could have found the bad component without the use of the FLIR.

Hoping that...
