WGV2000 in Omega Race, zooms out, thoughts on my t-shooting?
I have owned this Omega Race for 5 years, it's been a solid part of my gameroom but it has always had small issues with the monitor. Last night a problem popped up that I thought I had eliminated: The monitor will zoom out to nothingness with retrace lines appearing as it zooms out. As soon as it has zoomed out, just as quickly it will zoom back to a stable normal sized picture. A minute or two later it will start to zoom out again. I thought this was a cold solder joint on the power PCB, but I guess not.
My thought at this point is to steal the HV cage from my Asteriods Deluxe (also an WGV2000) and move it into this game. This would isolate it as either an HV cage problem or a bad HV in line diode. Good call, or not?
What I've done to this machine since I have owned it:
1. V2000 cap kit. Reflowed almost all solder points on HV & Deflection PCB. Installed some new thermal grease on a deflection component/heatsink.
2. Bob's new power brick caps installed (similar in size to Atari's Big Blue).
3. Capped the power board, reflowed all solder points.
4. Capped main PCB and sound board.
5. Gave it a new HV diode.
I have a now rare, new, HV diode if needed. Bob's been out of stock for awhile now, so I don't want to use it. I have no way of knowing if my HV is too high and that has cooked the diode, I do not have a meter that can go high enough to take a measurement.
