I just recently capped a wg4600 and am using it in a cab with a 48 in 1 pcb. The picture looks good, but I can't seem to get it "centered". If I adjust the pots to fill the screen, then the right side is cut off. If I back off the adjustments so that the right side (of the vertically mounted monitor) is visible, then there is about a 1" space on the left side. Is there some way to adjust the vertical position on a wg4600?
 
There are vertical centering jumpers on the chassis:

Let me find the diagram...

Ah, here it is:

Well... Moving the jumper helped, but it still needs more. It looks best with the jumper in #3. Any other suggestions? There's also i slight "wave" on the extreme right side of the screen - not a hula, just a small, stationary ripple.

Try tweaking this pot in the center of the right daughter board to see if it fixes this issue:

Yep, already tried that - actually I HAD to tweak that one to get the monitor to sync initially. I've read over all the info on Bob Roberts site, and I came across this:

If you still are having trouble with sync circuits, some V/H bds require a jumper across C315 eliminating it from the circuit when used with certain game pcbs, while others need C315 in circuit. There is usually a bare wire jumper on the solder side of C315 that can be cut open or tacked together as needed

Do you think this woud help? Could this be a sync issue? Thanks for your help Mod, I really appreciate it! :)
