I have fixed a few arcade machines but i am absolutely stumped on this one...
So I just recently got this Pacman / Galaga machine and it needs a little work: When i plug the machine in and boot it up, it works fine. Apart from a little hazing and jittering around the text when i am looking at the screen without anything really animating, it looks fine but if i play it for a few minutes or let it sit for about the same amount of time, it goes to a grey screen that looks like one of the syncs is messed up (looks like the screen adjustment is folded into itself if you can kinda picture it.) I need to get a new usb cable for my phone and i can upload some photos to show you whats going on, but i cant atm. When i do anything after this happens it doesnt change anything on the screen (IE: no changing colors or change in "pixels" so I was assuming its either a bad monitor, or something with the powersupply (my tron machine did the same sorta thing for a while but it was still outputting to the video kinda.)
Normally I try to figure this out but I cant seem to find any repair guides/schematics for this one so I am stumped.
Thanks
