I'm working on a Missile Command and am having some issues with what iIbelieve to be the pcb.
I replaced the power switch that was shattered and restored power to find the monitor (G07) was dead as well. Replaced with a completely rebuilt chassis and started to focus on the AR board. This needed to be replaced because there were components missing. Now I measure 12V, 5V, and -5V on the Missile Command pcb and all voltages are correct. I am getting a blue screen on the monitor and the P1/P2 buttons are lit solid. The game doesn't react to coin switch or test mode.
Did I miss something , could this still be a power issue, or is this most likely a board problem? I will replace the Pokey, and CPU in the board tonight but just wanted to get some inputs to speed up troubleshooting.
