#GARY?
3 messages in this thread
A couple years ago, my monitor display started very occasionally
twitching–a kind of darkening or shrinking (recovers too fast to tell
which) here and there around the edges–reminds me of the way a jellyfish
pulses.
More recently–on rare occasions at first, but now at some time during
almost every 2-3 hour session–I'll get full screen darkening and/or color
change, and/or dark streaks horizontally across the screen, particularly
between (or on) lines of text. Occasionally these will get so heavy as to
leave the display unreadable for a few seconds, but–so far–they have
always gone away enough so I could finish my tasks.
A salesman, on learning that this is accompanied by no other I/O problems,
suggested I need a new Gary. But Gary _does_ relate to floppy functions,
which I have no problem with, and seems to have considerably less to do
with video than either Denise or "HY200 VIDIOT," judging from a cursory
inspection of the schematics in Appendix F of the A2000 manual.
Does anybody have any suggestions?

Bart,
My first place to look would be the monitor itself. If at all
possible, try your Amiga on a different monitor…see if the same symptoms show
up.

Bart,
We have had a similar problem, and originally the mother boad was replaced. The
problem was not cured. We much later blew the Gary chip altogether,
unplugging/pluging in a printer with everything on, the chip was replaced and
out monitor problem remained. The monitor problem we had was intermitant and
went away for many months only to return so bad we took in in for repait. It
appears it is a chip in the monitor that needs replacing. I will post its
details tomorrow as the information is at work. We have not been able to source
the chip to repolace it son the monitor, a 1942, is currently dead.
