Hello,

I just replaced the ballast and starter in my Q-bert marquee, and something funny is now happening to the top 10, the top are garbled.

Also, I just did a chassis swap on the G07 in my Q-Bert, and I'm getting some sweeping lines running across the monitor. I checked the ground, and everything looks okay... Here is an animation I made:

Thoughts?

Riptor's talking about the high score table issue in another thread, apparentely if your voltage is low it will do this from time to time. You can at least temporarily probably 'fix it' by resetting your high scores.

As for the monitor thing, there's a ground strap that connects where the back door hinge is. Try disconnecting some of those grounds. If they're already disconnected, connect them :) Mine was doing the same thing until I disconnected them at that point.
 
Thanks for the tip! The top 10 reset itself overnight (I dont have a battery installed at the moment) and I found the source of the wave issue;

I pulled the cab away from my neo geo 4 slot for service, and the wave went away. So now I have to find the leak in my neo....
