Re: Help with Samsung 50" Plasma

Ok. Anyway to test the psu otherwise or does it take hooking up to a good y-main board to get the voltages back to where they should be. I'll take a look at the y-main and buffers when I get home.

Re: Help with Samsung 50" Plasma

Thx. Will do. Not arguing but what would cause the powers supply board to not show the right voltages if it was a Y board??

Thx

I have a Samsung T5054/XAA. It is about 6 years old.
Last week I was watching it and the screen went blank, but you could still hear the audio.
After some searching, I decided to pull off the back and test the voltage on the SMPS. I pulled off the CN807-808-809-810 leads and tested the voltages of the Vs and Va terminals. The Va tested fine at 63 volts but the Vs showed 0 volts.

Should I assume that this board is bad, and either replace it or have it rebuilt? or is there something else I should test as well.

I did talk to a local repair shop...
