Hey i got a speed race cabinet a few days ago (old old old 1974 cabinet) and the PCB had some problems and i did a few things and replaced the caps and the board works sound controls etc but no video.
I'm pretty sure its the board as it had a sync problem and i saw the game on the monitor kinda but now i see nothing.
i'm wondering if the video should look like the picture below thats what it looks like if the game is pluged into the cabinet or not.
