Hello and thanks in advance! I just swapped out my ms. pac-man pcb in the original cocktail with a Jamma to ms. Pac-man adapter and a 60-1 board. The left directional does not seem to work with the new setup. I put the pac-man board back in and it works fine. Also can't get the screen to flip to test player 2 side. Any suggestions?
Also, I'm having some color washout/issues, completely redone chassis and monitor, but I think it has something to do with all of the components being close together. When the monitor is opened up/unlatched, the colors look great, but when I bring it back towards the cocktail cabinet I get corners that are sharp, but the middle is washed out. Any suggestions on how to shield it? I think it may have something to do with the speaker placement?

Pitch the 60 in 1 board in the trash. Problem solved. You are welcome.

Well, I would sell the 60 in 1 and adapter to some moron, put your original board back in and get one of the many multipac kits out there that use your original board. I suggest Mike Doyle's 96 game kit.
When you buy garbage you get garbage results.

Think cocktail mode is set in the test screen menus, somewhere. Flip DIP #4 then switch on to access the test screens. Sounds like your pac-to-jamma adaptor may be the cause of the control issue. Look up the Pac-Man and JAMMA pinout and make sure the LEFT pin on the pac side is correctly connected to the LEFT pin on the JAMMA side. Monitor issue could just be that the screen just needs demag/degaussing. Is the degauss coil working? Other than that, it's likely as you say, and the speaker (or possibly a PSU) is causing the issue.

Thanks big10p, the only one with useful information. I picked the 60-1 because I didn't want to have to gut or re-wire the original pac-man cabinet and still be able to play some other classics. I'll give it a shot making sure it is set to the cocktail mode. Can't say if the degauss coil is working or not. Since this monitor was rebuilt, I assume it does work. Just trying to figure out how to shield the monitor from the cpu/speaker so I don't get the fuzzy lines.

Pitching the 60 in 1 is good advice. Unless you hate video games. Its emulation is garbage.
-
I think the 60-in-1 is a great little board. Yes, the sound is bad on some games, but apart from that the emulation is good, IMO. Good value for money. Each to their own though, I guess.
-
Yeah I haven't had enough experience yet to identify if the emulation is bad or not. Just wanted to have access to a few more games and it was cheap enough. So for whatever reason, the left position is working! Not going to ask questions. Left it on upright mode so player two can use the "fire" buttons that are only on side one. I've had issues degaussing before, where it really didn't fix the picture. Any other suggestions on how to shield the monitor from the rest of the cabinet to avoid the discolorations?
-
Is the speaker the original one? Like I say, it may not be the speaker causing this, though - could be a PSU. A couple of pics of the inside might help to see what's going on.

Interestingly enough, when I rotate the cabinet, 180 degrees, I don't get the washed out coloring. Although the coindoor is now to the wall, it's a small price to pay to get a good picture.

You need to degauss the monitor
Depending on the model you may see it clear itself up over the course of a few days Most monitors fire their degauss circuit on cold startup.
