Question about Mitsubishi WS-55908 55" Rear Projection Television
My blue CRT coolant leaked onto my signal board and a reputable board repair place said the 7A00 IC was bad, a Panasonic MN12857K MA2, 44 PLCC and it is no longer available. Any idea where I might find one? I am able to desolder the old and put on the new. The tv doesn't have that many hours on it and I'd hate to make it landfill. Thanks much.
Sorry, but when the coolant leaks down onto the small signal board, that board will never work right again. The fluid penetrates the board itself since the board is double sided and has many feed-throughs. The fluid gets under the surface mount parts and just eats through the copper traces, part leads and board itself. After trying many times to clean and restore those boards, not one has ever worked right again. The boards are NLA from Mitsubishi, so the set is done.
