I purchased a Super Pac-Man with the monitor inop (sound, no picture, plays) and I replaced it with a monitor from a Pac-Man (I think) that I got for free (the guy replaced it with an LCD and was going to throw it away), now I have a picture of a garbled mess. I've only dealt with jamma in the past and I'm not sure the ground/sync and RGB are correct. Trouble is, I'm not sure which monitor I have, it is an RCA 19VJTP22 tube. See attached photos:

I would appreciate any insight!

Thanks for the quick reply, but no joy. I have messed with all of the H/V adjustments and I still get the same.

You adjusted the L351 in the middle of the right daughtercard and couldn't get it to sync? Did it get better or worse?

Try wiggling the right daughter card a little and see if it helps. If so, you have cold solder on it.

And has this been capped yet?
 
Negative Sync Wires

Should the neg sync wires be jumped? I noticed in Bob Roberts cap map the K4600 has a jump on the sync wires but the G07 does not appear to have it jumped.

I tried flipping the 3-pin connector (neg sync) and it pretty much did exactly the same thing. I'm beginning to believe the sync wires should be jumped, but I'm not sure.

It got worse, messed with the daughter card and wiggled all the wires to see if I had a bad connection, nothing changed. I don't believe it has been capped, but the jumper wire (which was snipped off when I recieved it) looked like it had been hot. The monitor looks (I know this sounds crazy) new. As if someone had recently replaced it. No dust, boards are clean, wiring looks new.
 
1) did you try your adjustments after that?

2) is that yellow wire part of the ground wire setup?

Yes, it did get better (see video) I can make out 5 seperate pac man screens. The yellow wire is the ground from the board and is the RGB ground wire. In the schematic from Wells-Gardner it has a ground to the sync, but Bob Roberts doesn't show a ground attached.
 
The ground on the 3-pin is a duplicate ground.

Okay, I just so happen to have a Super Pac here at the moment, so i went and looked at the video connector. It is:

Red
Green
Blue
Black/Yellow
Empty
Empty

White/Purple
Grey
Black

So, it appears your first setup was right.

Although this monitor is a K4900, it should hook up the same.

It appears that you should be able to adjust it out with either the H Hold pot on the bottom of the X/Y card, or the H Freq (L351) pot in the middle of the X/Y card.

Don't suppose you have another of these monitors around that you could swap cards on?
