Omega Race + WG V2000 B+W Vector - Huge overscan after left on a while
Last night I had my Omega Race with a WG V2000 monitor on for about 6 hours. The first 4 hours it worked fine, though had that typical "hot 1970's electronics smell" (pcb's from the boards burning off I'm sure.
At around 4 hours I walked by and noticed that the rubber band borders were now on the very edge of the screen instead of about 1/2" from them. At about 5 hours they were totally gone and the text and ships were significantly larger from the middle. A bit later they were much much larger so that the center score/remaining ship box was now filling most of the screen.
I turned it off for about 1/2 an hour and let it cool down. Turned it back on and amazingly everything fit in the screen. About an hour later it was overscanning a bit again.
The monitor has never been re-capped and nothing else done to it other than a through hoze cleaning about 3 years ago and worked fine since. This is my only B+W Vector monitor and I have only worked on color raster up to this point.
So, experts, what do you think the problem is? Caps? HV? HV Diode? Transistors or other monitor components? Or something on the main OR board itself?
I have a cap kit ready to install, so that will be the first thing to do. But if I gotta pull it out, any tips on what could be causing the huge overscan over time would be appreciated. Thanks!
