I have a Nanao MS8-26 pulled from a Daytona USA. Sent it to off and had it capped. It works, but for the first 5-10 minutes of turning the game on, the screen rolls, and it has traces of gibberish on the screen. After 5-10 minutes, the screen stops rolling, and the gibberish is gone. I swapped out game boards, same issue, so it's not the game.

Any ideas?
 
Reflow the solder?

Try soldering the IC 101 and Ic102
and Q752.
Good LUck!

So did you ever find the solution to this problem? I have the same monitor in a Virtua Cop 2 that behaves the same way,
" the screen rolls, and it has traces of gibberish on the screen. After 5-10 minutes, the screen stops rolling, and the gibberish is gone."
I installed a cap kit a little over 2 years ago and for a wile it was working fine and it has only been used a few times and has gone back to the same problem. After it warms up for ten minuets or so it runs great.
Beginning to wonder if I got some bad caps or if it's something that's not in the cap kit. I believe their were a few caps not in the kit. Guess it's time to buy an ESR meter.
Here's a youtube video I found. It's not my monitor but mine has the same screen problem.
 
boys i have an idea... let em run till they look good, then start hitting one component at a time with freeze spray(or a upside down can of duster if youre cheap like me lol) and see if you can find a sore spot....

Thanks, that's not a bad idea. I don't think I have either so I'll have to stop by my local electronics store and get some.
I decided to make a video of my monitor showing what it's doing. On top of the monitor problem the audio amp died as you can tell by the scratching noise in the video but that's for another thread.
