I have a double image on my robotron now. I've had some power issues (its using the arcadeshop switching power supply).

Sound is also intermittent. Usually turning it on and off gets it back. Tried turning it on and off several times but I still have the double image.

Is this power related or something else? Loose connection perhaps?

Thanks for the assistance.
 
What direction is the doubling? Horizontal or vertical?

If vertical, have you tried the vertical synch?

I just had this issue with a friend's Joust. It turned out to be the monitor. And for some reason the sound board went out also (I think it is the amp). All of this happened after the +12V on his power supply board went south. It took a new sound board and a repacement monitor to fix.

It's vertical.
 
Sounds like the same thing. We just swapped the monitor out. I haven't pulled the chassis yet, but just by looking at it, it definitely needs a cap kit (a couple caps are bulging). Whether it needs anything else is yet to be determinied.

When I was trying to adjust it, the vertical synch acted like a bad solder connection at the pot as well.
