right place to ask, hopefully someone has a schematic.
I'd say that you have something bad in the data path fromt
he cpu to the video chip (obviously). Since it is painting the
the screen in a stable fashion, I'd think the video portion
of the chip, and memory is working, but the data and
commands into that chip and circuitry is scrabmbled.
Does the display stay stable, or do the characters change
w/o any keyboard input? If they do, then you may have
other damage too.
Did you drop it, or know of any event related to the
start of the symptoms? Might help others here help
you if so.
