Plugged in old jammer game board and it works but my 48 in 1, which worked last night, has messed up video output. (scrambled). The game seems to work other than video (makes the right sounds when I push buttons) is it possible for the video signal from the board to get messed up and can I do anything about it?
 
1) Do you have the CGA/VGA dip switch set properly?

2) Have you tried adjusting the hold pots? Monitors won't always lock the same way when swapping boards...
