LG 47LW5700 PSU Conmpatibilty

[THX11]

G'day all, my housemate has asked me to take a look at his dead LCD. It was originally firing up and then shutting off, now nothing at all.

Have the back off and can clearly see a little blue capacitor (C603) has lost its insides as most of it is missing. Pretty much right next to that it also looks like a mosfet has arced out and caused damage (Q602).

There are two numbers on the board...
LG PN EAY62169801 and
PCB PN eax62865401/8

Does anyone know if I buy a board with those same numbers will it be compatible, even if it's out of another model type? Or is there pots to adjust etc after replacing the psu?

Reason I ask is I can find several listings for that PSU, but they are all pulled from other models.

Hi,
Normally, if the PN's match, so should the boards.
If in doubt, try to search by "TV_make_model power supply board" and see what you get. It is very likely that if the boards you find come from different "variations" of the same maker, they are the same. A lot of manufacturers use the same PS boards in various models, the feature diversity coming from main boards and firmware.
Do keep in mind tho that replacing the power supply is not 100% guaranteed to fix the TV. It may have failed due to another board putting too much stress on it.

You need to match the PCBA (PCB assembly) # EAY62169801
PCB PN eax62865401/8 is the Blank board P/N which can be stuffed to make variation of the PCBA for various model.
