Well I mostly work on pinball now but this came into my shop and trying to figure it out, very rusty with video game boards.

I have a Super Pac man that the monitor displays garbage on the screen. You can credit up and play "Blind". Is this an issue with the 6809?

Thank you for your help

try turning the horizontal sync potentiometer on the monitor chassis first before you do anything else
just a little bit ought to do it. I have a plastic screwdriver so I don't short something out but you should be EXTREMELY careful and DO NOT try this if you are a noob
read up before you start fooling around back there as you can really hurt yourself and don't say I didn't warn you good luck
 
I thought of that before, will try it...
Definitely not a noob, I have been rebuilding monitor chassis for a very long time, just got out of the arcade game side for a while.

Thanks for the advise I will try that first
