I have a fully working asteroids with a G05-802, but I also have a 2nd board and 2nd monitor (v2000) that are not working properly.
I have capped the faulty v2000 (including the C100 & C101 as one of them had failed) and replaced the deflection bottlecap transistors & checked for shorts. Leaving the good pcb board in the cab, I place the v2000 in and get the following result:

The B&W Vector Monitor Guide (point 17) says that if video information is distorted (letters and figures are "crinkly") check the 90v power supplied by the EHT unit, if that looks good check the electrolytic caps... well, I've replaced the caps during the cap kit so it's unlikely that's it. Does the pic look like the "crinkly" the guide speaks of?
thanks,
Tom
