I have a galaxian that I have got not working and have gotten to a point where it will play but there is a doubling of the graphics. Not sure if it is a monitor or board issue. I am leaning to board. I tried the focus and other nobs on the monitor with no luch in change. I also tried the 3B 74LS86 Ic as in the troubleshooting guide it had indicated that it may cuase image distortion or doubling. Still not luck. I have included a picture to see if anyone else has seen this issue and may be able to help.
Thanks

So I have never messed with convergance and this is a g02. can you give me some steps on how to fix that? I think your talking about the neck section? correct?

G02... that was the big 25" monitor, right? Never worked on one, but you can find the manual online. Convergence is pretty similar on all monitors though... you'll be adjusting the neck rings. Remember to mark the starting positions so you can at least get back to where you started. I bet just one of the rings got bumped at one point....
 
yea it is the 25" g02. I got the top and bottom to be good. but the midfdle has not changed. I just adjusted the next board pots. There is a pot for static blue in the middle looking like the "flux capasitor". Is that what I adjust?

Convergence on a G02 is a nightmare. Check out page 7...

It's got it's own "convergence board"....very similar to the WG4500 (if you've ever had the joy of working on one of those).

I have seen and read that document and it is a chanllange. Never did convergance so whated to get the jist of whay I'm doing and if I'm dooing it correct.
 
I had convergence problems on my Galaxian as well. I saw that convergence board and decided it was the end of the WG4500 because it's converging nightmare with one like that.

If you want to save your patience and time, get another monitor...
