Hello! I have been working on this stupid tapper for a week now. The screen has a very very minor up and down shake; it's too fast to video but in real life it's so bad you can't play it (probably give someone a seizure)

I've seen 5-6 posts on here about the same issue but no actual solutions. Monitor is tested good in other games.

I am running a switcher with adapter. I've heard it could be the factory shielded cable causing issues?
 
Whenever "shake" issues come up, I always start with pots. Run them back and forth and spray them with some DeOxit. Is this a chassis that hasn't been serviced?

Edit: So it doesn't shake in other games it looks like. Game board/sync?

I replaced all the pots already. New caps new fly back etc. it works fine in other games, and other Chassis in this one shake up and down

Oh so even a completely different chassis with the same tube does it then, yet in other games all is well.

Man, I'm out of my range on that one. Compatibility? Maybe others will have some cool tricks to try.

Does the test mode have the shake as well? Not sure if that game has one.

That might eliminate tube vs board issue?
 
My Tapper has a slight shake as well, but I don't care at this point as it was a complete resurrection and I'm done doing anything else to it, alcohol helps not notice it 😄
 
Looks to be a known issue

 
Get rid of that nasty switcher, it may resolve the issue. If not at least you'll have a better power supply.
 
Are you referring to the "shake" of the interlaced video these boards produce? It's more of a high frequency "flicker" than a shake to my eyes, though.

I don't know exactly, but it feels like it goes up and down repeatedly very very fast and it's hard to play it.
