Missile Command Not Working - Blue Screen, 5.8v - where to start?
Just picked up a non-working Missile Command and am trying to get it going.
The best I can do is a blue screen with solid lit 1p+2p leds. The game will not go into test mode. One time I got it to boot with the counters going crazy and the 1p+2p lights flashing. I have reseated and cleaned all chips. I have swapped CPUs. I cleaned the edge connector and I am testing the +5 voltage on the board at 5.8V-5.9V. Obviously this is high. The AR will not adjust down using the pot on the AR-II.
So, I am guessing I should rebuild that power supply, right? I would think the board might boot with 5.8, am I wrong?
What else should I be looking for with this game? Replace all the sockets?
I was also thinking of getting the braze kit so I could remove the rom sockets out of the equation.
Any ideas? tips? This is my first MC and am not very familiar with it.
Thanks!
