Taito Chase HQ arcade pcb repair #3
I was sent this untested pcb and when I wired it up found there was no video output on RGB – very strange as sync was present, so this caused me to check and re-check my wiring a few times. When examining the pcb closer it was clear the TC0070RGB custom had been removed, presumably to fix a different game. I had a spare one so I soldered it in and everything was back to working.
