Thanks to this forum I was able to fix up a Bally GameMaker!! ...but the CRT died after about a week of use. I've been trying to use a VGA breakout cable along with instructions for a V7000 to hardwire a replacement 4:3 LCD screen, but I'm not having any luck with my V7200. Hopefully someone can provide a little direction for me:
1. Does the monitor's AMP receptacle (19-pin, same as used for the coin hopper) need to stay connected to power the two boards that used to manage my CRT? Or can I connect my VGA breakout cable directly to the female pin spots of that connector? (which would cut power/etc from moving upstream to those CRT controller boards)
2. Can anyone confirm which pin(s) on the AMP receptacle or the main board's monitor cable would be the ground on my V7200 model? The closest schematic for a V7000 shows main board grounds on pins 3&13, but those are both empty on mine.
Thanks in advance for any guidance!
