Samsung Plasma TV Model PN50A550S1FXZA

[tsteevie]

I have a Samsung Plasma Model No. PN50A550S1FXZA, S/N B46V3CQS101329V. I heard a loud pop and now I have no picture. The sound appears to work, but no picture. I disconnected everything, and took off the back. I did not notice any capacitors which were blown or bulging. Also, I did not see any fuses blown. (all white fuses and appeared to be intact) When I power on the tv, I hear a one big click and hear the Samsung start up tones. Still no picture. I tried the menu on the remote and it will not show anything on the screen. All black. Can you help me diagnose the problem? Some of my internet research suggests the Y sustain board.

I am a novice and would appreciate any help. Thanks!

If you can, take some pictures and post it so that everyone can see how the TV looks inside

Y Sustain is a good bet. Remove it from the set and check the fets under the heatsinks for shorts.
