I finally got around to installing an accelerator cable for a Sega Hang-On on picked up. While doing so, the image went from good to what you see in the attached images. It looks like the sprites are a bit messed to me.
I can't be sure, but I think it actually might have gotten stuck in that state while I was messing around in the test screens (all the ICs tested "Good" BTW).
I checked my game voltages and everything is good there. I also played with the pots on the monitor to no avail.
Before I go any further, I wanted to get some opinions on where to continue my search. I am planning on un-plugging/plugging the cables on the PCB next. Then roms... then I would have to move onto the monitor.
One huge problem I can't figure out, is how the heck you troubleshoot a monitor on this game (Upright)? There doesn't seem to be any direct access to the chassis for testing purposes.
