Dig Dug - G07 - monitor test

[yoharv]

Hello:
I'm pretty sure this Dig Dug I picked up needs just about everything.... including PCB work.  But is there any way to tell/test the G07 monitor to see damage or even maybe see possible quality?  As you can see from the video I'm posting I just get horizontal scrolling 7s, and the only rear control that does anything is the dimmer/contrast.  So can I like hook this up to a PC or something like that?
Thanks

you have board issues and monitor problems.

check you +5 on the board.

and adjust your V-Sync on the monitor.
