I've got a faulty LCD controller board from my TAM, which required replacement. Knowing I couldn't get the part I tried everything imaginable to try to get it to work, but I suspect it was a faulty IC or flex ribbon cable. I ended up finding a replacement part from the Netherlands, popped it in and haven't looked back.
What the board does is interface the standard VGA output of the 5500/6500 board to display video on a PB3400 LCD panel. It's not a pretty board and doesn't look particularly hackable. I've noted before how much of a mess the TAM is inside; piles of ribbon cables, custom boards here and there, mostly off-the-shelf parts with customised extras on top. Good then that the outside skin looks so nice, but it's like a renovated old house: looks good on the outside, but take a look on the other side and check out all the bad things patched up
