Re: Samsung PN58C550 Blank Screen with sound
Ok so I purchased the upper and lower Y board from a repair shop that was about an hour from me. I installed the new upper Y board and voilà Back to life! My question is should I replace both upper and lower boards at the same time? I still have an issue that was present before the TV broke down completely. It was a wide pinkish line that goes across the screen only when White is the dominant color. Anyone know what failure this is? Did this contribute to my blown board? Also should I check any other points before I put everything back...Leave a comment:

Re: Samsung PN58C550 Blank Screen with sound
After further inspection and peeling back the glue over the components, I noticed a current regulator at the very end of the board was blackened and blown. Where can I find the schematic for this board? I am going to have to replaced that component also!Leave a comment:

Re: Samsung PN58C550 Blank Screen with sound
I found the bad part on the upper Y buffer. It was a resistor marked 470. Anyone know where this exact part is sold and the actual part number?

Re: Samsung PN58C550 Blank Screen with sound
I have the PN58C550G1FXZA, with similar issues. The TV is less than three years old. I was watching my plasma and herd a fairly audible "pop" noise. Then a second later the screen went black. I mean black, no back light. I watched and executed the startup test from samsung on youtube and no self test started when I jumped pins 3 and 4 on the logic board and jumped the ps_on to ground. My logic board led flashes the top led once very quickly and then hold steady on the second led for 5 seconds on and 1 second off. I have replaced...Leave a comment:
