Aha
One learns someting every day!
The A series is the same - different motherboards for different screens
The 14" XGA and 15" XGA seem the same, the 15" SXGA and above are all
different chips.
I did a mobo replacement with an unknown Mobo
It turned out to be for an A20P, installed into an A20M
The display is all messed up, I have no idea if the mobo is good or bad,
this can be the result of the mismatch. I did try another Mobo, and the
display looked perfect (sadly, that one had the dreaded CRC error)
