Plasma Y board IGBT equivalency question

[Biruslapio]

I have two TVs here with both Y-SUS failures, one LG and one Samsung.
The Samsung's Y-main shorted one FGD4536 and one RJP63K2(there are two in parallel)

I have the FGD but I only have one RJP63F3, which is different from the K2, so, can two 30J124 be put in place of two RJP63K2? are they equivalent?

Also for the LG two 30F131 shorted, I have some FGD4536 (the same that are used on the samsung), can they be also be a substitute without issues?

RJP63F3 and K2 are 630V 30A IGBTs, but their rise/fall time and other internal variants differ.

30J124 600V

FGD4536 360V

30F131 360V

Well, no one bothered to answer.

I will report then, LG TV, 30F133 or 131 and FGD4536 are interchangeable, but the sus board was not operating normal, the image has some issue with proper sustaining and after increasing VS by 5% and resetting the configs, the tv powered up on a static background + white menu with energy saving disabled, that put a enormous strain on the Y board and it died again, **** off.

I have not tested the 30J124s in the Samsung yet.

be nice to know the model #'s. pics ?

I did not open the thread to ask for help with the repair, just the IGBTs thing, ended up discovering on my own.

Well I repaired the samsung Y board, it is a E series 43 inch, fault is as follows:
1 capacitor 331k 1kV blew up and shorted a RJP63K2, FGD4536 and a SF10A400HD diode, replaced the RJP pair with 30J124 and it works fine, however there are multiple black horizontal lines, I did not measure the buffer with care, it is faulty(open circuit on a lot of pins) and will need replacement.

For the LG it is a 50PN series and my next move is to buy some scrap boards and try to replace the mosfet drivers.

Re: Plasma Y board IGBT equivalency question

are you sure you have the ribbon cables inserted correctly ? common issue when replacing y board.

Re: Plasma Y board IGBT equivalency question

100%, like I said, all of the Y-buffer pins where there are missing picture are open circuit, while the others have the standard 0.8V.

Late update but, it is working perfectly now after wapping the buffer board.

Have not heard of this before, can you explain.

Wapping is swapping minus an s.

Re: Plasma Y board IGBT equivalency question

oh... I was wondering why there were 3 responses and one of them a "lolololol", yes, I meant swapping, I don't even know if there is a slang called "wapping", but it cannot be good (google says it's part of london).

LOLOL I thought it was a new technique or something.
