RJagers!

I bought a dead KDL-60EX720 with a bad main board for next to nothing. I do it a lot...source the board, fix it, and I have a TV! However, this board is proving difficult to get hold of. I have heard rumors that boards from other models may be compatible, like the EX723...but this is unconfirmed. Sony no longer supports 2011 models, so they don't have an answer. Does anybody on this forum have any information about this? Thank you! The board number in the TV now is A182155C.
