I just had this game shipped from Florida to Wisconsin. Seller says picture was fine on the monitor when it was shipped. I plugged it in and the picture has a slight wave going through it. It has a modern switching power supply. I checked voltage and the +5 was at 5.66 so I turned it down to 5.0 but still has a wave. Is this a monitor issue? Or could the power supply be bad? Please help! It has a wells gardner 4701 monitor.

Thank you

your 5.00V at the power supply isn't what's getting into the board.

I don't know the power assembly in Burgertime, not something I've needed to do anything with, but if it uses the same kind of fuse holders as Pac-Man then that's probably the source of your problem. it sounds like you're describing hum bar. what part of Wisconsin are you in?
 
Does the picture wave like a flag in the wind, or is there a dark bar moving across the screen?

Several kinds of things can cause that type of issue, and one of the first things to do is check your power setup, starting at the wall.

Make sure you have a clean power source, the cord is good, then go through your line filter, fuses, wiring and power supply. If it's still a problem, then monitor diagnosis comes next.

Some pictures of the setup and video of the issue will help.
 
One of the reasons cocktail games have monitor issues is the proximity of the monitor to the speakers and transformer, which can cause magnetic interference. As I recall, many Midway cocktail games had metal shields installed to help block this. Possibly the shield is missing or shifted during transport? Interior photos would definitely help as @brokentoken has stated

The good news is that the original suitcase power supply appears to be there. If it were me, I would rip the switcher out of there and rebuild the original.

To @sfspanky's point...that switcher is rigged up pretty close to the monitor. You could (carefully) try swinging the top up with the monitor still attached, make sure it's secure, and then safely power the game on and see if the wave is still there. That would at least help give you some clues on whether electrical interference is involved.

No original power supply
 
I'd just be glad they left the suitcase in there. Sourcing a power board shouldn't be too terribly hard, though.
 
In a best guess do you think irs the monitor issue or something else??

Thx
Electromagnetic forces can also create anomalies like this. If you have moved the game to a completely different room/outlet, not sitting next to other games, and it's still doing it, it's for sure an issue on the monitor.

Try turning a few knobs on the monitor to see if anything changes…horizontal/vertical hold pots, brightness, etc.

Ok so I opened the cabinet door and layed the side down so I could see the monitor. I was going to adjust the power but when it was on its side there is no wave. The wave only occurs when I get about 3/4 shutting the monitor back down in the cabinet. Definitely interference from something in the cabinet. Ideas to resolve this??

I wonder if you have a non shielded speaker in your game. Usually, that would just cause discoloration on the monitor. Do you see that at all?

No just a slight wave like a flag in the wind. When the monitor gets close to the speaker/old power supply is when it starts. No discoloration
