Re: Vizio P50HDTV20A Power Issue
Did some more checking. The board with the heatsinks on it on the left when looking at it from the back I think has some shorted FETs (Components screwed to the heatsinks).
D5003, D5001, D5005 all have continuity between the 2 outside pins.
All of the fuses are good.

Vizio P50HDTV20A Power Issue
I found a Vizio P50HDTV20A 50in Plasma on the side of the road. I figured it might be fixable so I grabbed it.
When plugged in the light in front is amber and turns green when turned on. Nothing shows up on the screen and I do hear the speakers pop slightly when turned on.
The power board is a Samsung PSPFS561A01A. For voltages I measured all the little pads I could find. All capacitors look fine. I did replace one one each of the Display Boards. (X and Z I think they are called?)
Vs: 208
Vg: 14.8
5Vsb: 5.1
A12V: 12.0
Vamp: 23.6
VT: 32.6...
