Working on a tempest board, all voltage on AR and board measure good with exception of X Y out AC are 0v. I have not plugged the monitor in. Game not playing blind. Will not enter test mode. Volcano LEDs are stuck on, but probing pin 40 of the 6502A it is not resetting. Hitting the reset button will toggle pin 40. I confirmed the dips that it's not in freeze mode. Plan on rebuilding the AR even though voltages are good. What should I be checking on the board itself?
