Re: Samsung pn58a550s1fxza powers on, no picture

Awesome! Thank you very much! Now lets get this thing up and running.

My Samsung pn58a550s1fxza powers up normally with sound but there is no picture at all. The panel is dark and it does not flicker when it is turned on. The first thing I did was replace about six caps on the power supply that were known to be bad. Still had the same issue. Everything I have read online lead me to believe that it was the y-sustain board. I ordered a Y-sus and both buffer boards and replaced them all at the same time. I still have the same issue. Now I'm leaning back towards the psu again but I don't have a service manual so I wanted to ask if anyone happens to know the voltages...
