My system started exhibiting a wierd problem this evening so I need some
help in diagnosing it. I have a IIgs with a PCT installed. I've had the
PCT for three months now. Till today ...no problems. This evening while
in the finder, I executed the program to activate the PCt and get me in
MSDOS land. This usually causes the "clear & jump" {no other way to
describe it} and then I get the usual messages while memory is being sized
etc. Well tonight the moniter displayed horizontal bars, as if I had lost
the horizontal sync. Powering cycling the monitor relieved the problem.
All is well until I run another program which fiddles with the screen's
attributes {still trying to localize it further} and the problem comes up
again. I can't seem to make the problem happen in Apple mode. It
therefore seem certain it is PCT hardware related.
The obvious choice would be the color switch board.
Has anyone experienced this problem?

I've had that problem with my monitor losing H-hold and I also have a PCT. I just adjusted the H-hold (or was it the V-hold?) and that solved it. I's been about 4 or five months now and I t hasn't happened since.
