Hello, the problem with this TV is it has all the Y and X voltages, but does not produce any image.
It had a TON of cracked solder joints on these boards, fixed all that I could find, but in the last test I forgot to plug in the Y-SUS to control board flat cable, it was left dangling and possibly some pins shorted to the panel metal ground, the X-Main buzzed quietly then blew up in 3 seconds after powering up, annoying.
Two RJH30E2 shorted, they are 360V 35A 1.7VCE IGBTs, the problem is I don't have any 360V IGBTs, only 300V or 600V, would two RJP3065 fit in? It's equivalent or superior in every spec except the max VCE voltage tolerance, looking at panasonic SS or LG Z sustain boards, all of them use up to 300V components, 30F123 or 2PG001 transistors, but this specific Samsung uses highter rated ones. I do not want to solder something that will blow up again.
The power supply, main board, Y-buffers and bottom "C" boards have been tested and are fine, what's left to suspect is logic, Y-SUS and X-Main.
