LG 50PJ550 YSUS & ZSUS Component part numbers

[simplytrini]

Hi all, I am wondering if anyone can help me with a problem? A customer brought in an LG Tv 50PJ550 for repair, after inspection of the TV I realized that the TV had been worked on by someone else and found that a few FETS are missing from the Ysustain and Zsustain boards. Can anyone help me identify the part numbers?
Ysustain: EBR63039802
Part Locations: Q02,Q03,Q22,Q24

Zsustain:EBR63040301
Part Locations: Q21,Q22,Q23,Q24

If anyone can tell me the part numbers, that would be awesome! Thanks in advance.

Well--The 42" version (Which looks Very similar to the one pictured) uses 30J124 and 30F124 for the 'SUS_Up and SUS_Dn' IGBTS (That always seem to fail in this series)--Although I cant remember which is which offhand and haven't any data/diagrams.....

I expect that the 50" uses much the same--but with an additional one in parallel, so three for each function (There's a place on the 42" version for the additional IGBT)....

Dunno what ones your schematic ref numbers refer to though.....

I know all parts but can't remember what order they go.

They will be 51N25, 30F124 and RJP63F3

Also worth checking all the RD2003 diodes. Replacing both ceramic caps located on the ysus. Think they are 102j
