I acquired a Missile Command Cocktail with a dead PCB. So I pulled a Known Working board and checked the voltages. Everything Looked good at the 15 pin molex in the Power Brick, looked good at the AR-II, Had to adjust voltage from 4.85 to 5.03, Plugged in the working board and powered up. Check voltage at the board test points, 5.03, good.
Played a few games, walked away to let it run for a little. 3 hours later I hear noises and see a flashing screen. Self test now indicates RAM J4 and H4 are bad.
AR-II caps look new. Transistor failing and does go bad until it runs for a few hours?
