Re: Rca l37wd12 lcd tv
Here are some shots of the PSU, I noticed that there is a section on the bottom that looks to have gotten hot, looks to be one of the transformer windings.
I tried changing the startup cap 10uF 50V on the PWM PFC chip but that had no effect.
It's hard for me to measure the voltages on this supply as it has to be in the TV for me to power it up... I don't have a good selection of testing cables at my house. I was able to measure ~160VDC at the output of the bridge though.
EDIT: I just noticed that my attachments are messed up.
EDIT 2: I also just noticed that in one of the pictures of the bottom of the board there is mention of the P-ON signal I was talking about. I will work on getting some decent pictures of the mainboard soon.
