I replaced the ysus and xmain and voltages drop once I connect the ribbon cable from logic to ysus. No buffers were connected. Only board I have not replaced is the logic board. That is next.

Please report back. I have the same set. Originally, it was clicking when plugged in. I replaced four FGPF4536's on the Y and four 30G124's on the X. Now, it turns on but Vs and Va drop out immediately and there is no picture and no panel prime. At first power-up, the green LED on the logic board blinks a couple times about a second apart. Then the blinks slow to about once every five seconds. I don't know if I missed something on one of the sustain boards that's causing VS and Va to drop out or if the logic board is the problem. The set acts as if the sustain boards aren't connected.

I have a Samsung Plasma PN51D530A3FXZA, when i turn the tv on it sounds the chime, the red LED light blinks 5 times and then the tv clicks off. I've tested the fuse and its good, I tested voltage at Va, Ve, Vsc and I'm getting nothing. I have no idea where to start because I'm not getting voltage anywhere!

Ive done some research on this model and other models with the same symptoms, and its pointing at the main board. However if i can't run tests on the voltage i can't be sure.

I don't know if this will help.

Were you able to fix the tv with all the board replacements?

i found 5 bad components on one of my x main boards - the original. The other board had 3 shorted FETs. I bought a used y main x main and y buffer off of ebay. Hopefully, this fixes the issue. I will post when they arrive on monday.

Were you able to get the tv running again with the new boards?
