I can't speak for the 124 specifically, but in general, something has happened to your horizontal sync. From your description, it sounds temperature-sensitive. I suspect a bad solder joint, perhaps at the flyback or horizontal-output-transistor (or in those area(s)). Good luck. EOF > Mike Warning > warningm@prism.cs.orst.edu

The Exact thing happened to me, and it WAS NOT THE MONITOR! The problem really showed up whenever I tried t use a Re-set Proof RamDisk, OR Shadow (ver 1.1) Well I opened the macine up, thinkng that I was having problems with my new Z-Ram 3-D/4 Meg upgrade, I installed recently. Well to make a long story short, it was a pin connection on the GLUE chip that caused all the trouble. All I did was to re-move the chip, clean all the contacts, and then replace the chip. Bingo..... Problem solved. As an aside, I also did the same to the MMU socket connections. Havn't had a problem since..... #include (std. disclaimer> If you are unsure of your ability to do this, then DON'T.
