I have some X/Y boards for Samsung 50 plasma TV, some of them are 1080P (DF),some are 720P(DH), piled in my garage for long time. Today I happened to have time to repair and test against PN51D550 (1080P 3D TV).
I checked the boards all seem to have IGBT transistors blown.
I fixed some of them only due to not have enough transistors.
Part Number: LJ41_09422A (X) ,LJ41_09423A (Y).
Y board (DH)+X board (DH), TV works. (720P boards work for 1080P).
Y board (DF)+X board (DF), TV works. (original).
Y board (DF)+X board (DH), TV works.
Y board (DH)+X board (DF), TV not work, X and Y boards both burnt IGBTS again.
I don't have the 720P(PN50D450) TV so don't know if DF XY board works.
