I recently was having vertical collapse on my rebuilt 6100, so I decided that I would replace all 6 output transistors. Did so. Now the spot killer comes on and the game won't even play blind. I am getting EXACTLY 5V at the PCB test terminal, but both player 1 and 2 buttons are solidly lit, no blinking. The minute I hook the monitor up and turn it on, the spot killer comes on. When I power it up without the monitor hooked up, the LED on the board lights up and the game WILL NOT play blind. This game was working fine before the vertical collapse issue, and still played blind after the issue started. In fact, until I replaced the output transistors, it played blind. I really don't have time to keep screwing with this every weekend, and neither of my meters has a continuity tester. Can anyone help me figure out what might be wrong? I have an ARII rebuild kit and a new big blue, but I am tired of shotgunning. The transistor on the heat sink of the AR II is rustier than the color of Fritz's bearded clam. Could that be a problem? I restore these machines, and do my best to fix them when I can, but this one is frustrating and over my head. HELP.
