I have an Asteriods Deluxe that I am trying to repair and am somewhat new to the hobby. The monitor does not show a display and is black and at this point I have unplugged to try and get the game to just play blind, show blinking player buttons, or beeps, anything. At this point I don't get anything but a humming sound from the speekers.
I have changed out the Large cap from bob roberts on the power block as well as all the caps on the power regulartor board, the 2N3055 transistor, and the LM303 voltage regulator. l lowered the voltage from the pot of the regulator to its lowest point and I still get about 5.69 v (which I beleive to be to high) on the game board. no player buttons lit, no beeps, nothing. I also tried the self test switch with no different results.
On the game board I had changed all the caps and reset and cleaned the chips that I could.
Looking for some other suggestions to save this game.
Thanks
