to start with im completely new to arcade repairs and this forum but i recently came into a williams high impact football and a sega shooting master. i started with the high impact and now how the board fully functioning from what I can tell as it has all attract audio working. I dont have a monitor for either of these so i picked up the GBS and wired that in.
upon power up the lcd displays the rom check but never goes any further. the game continues to boot and move into attract mode but the screen stays frozen. the only way to get it to change is to unplug and re plug the sync wire and then itll show a now image but it is still frozen on that new on. i cant get a constant video out of this thing. im completely at a loss now as the manual doesnt give any help.
i have already tried the board reset on the gbs where you hold the button down for 8 seconds, all that does is gives me a new frozen image. ive also tried the auto function on the board and again nothing different. ive ran it off a 12v3a power supply then wired it into the 5v15a inside the cabinet and no change either. any one have any idea what i can do here?
