I have Final Fight game using this board, here is what it is doing:

No matter how much I adjust the horizontal hold I cannot get it lined up with the edge of the tube, the image in the video is as good as it gets before it starts to roll. The pots are really sensitive.
I had a guy locally, remove the board and replace the caps.
He said there was something wrong with the board, and there was nothing else he can do.
I will ship this board to anyone willing to repair, just need some quotes and arrangement info.
Thanks!
 
There's a pot on the board that will let you shift it over....

After fiddling with that pot, the image continues to roll, once the image shifts to the right. I also noticed when just putting a little pressure with my finger on top of it, kind of moves the image to the right, It seems like this is causing the problem.
Is this pot replaceable? If so, would you know the part number?
Thanks.

Here is a pic of the specific part on the board.

What board are you testing it with? I think the CMA-20 is a negative sync only chassis.

As for a replacement, You need to check the value of the pot, then find another of that value that fits that footprint. It doesn't have to look the same. Your issue could be with the hold pots, too...
 
Sorry, Are you referring to what jamma board is connected to it?

Or any board. I had this issue with one JAMMA board but not with another. Unfortunately, I needed it to work with the JAMMA board that was messing it up. I'd also fully recapped it prior to any adjustments, which may account for why adjusting that pot worked for me...

Yes, I have tested with a pit-fighter jamma and another final fight jamma board. Same result on both, I would also like to point out, that the image in the video, is as far as it will move to the right, even if I leave it like that, the image will move slowly to the right and eventually start rolling, so the image does not stay in place for too long. 10 mins maybe?
 
Make sure you only have the negative composite sync connected to - what? Pin 5, I think? Been a while since I messed with one...
