ooooooooooooook...
So an update. I capped the board and replaced the flyback... nothing. Then while talking to someone, they informed me (maybe reminded, I remember reading something about it but forgot) that there is a dip switch to downgrade to low res on the blitz board.
I turned my blitz and ultimate mk3 machines back to back, flipped the switch, hooked the blitz video connection to the mk3 connection input (diff color wires, but all connected right up) and powered both on... nothing on the monitor... sigh...
Thinking maybe the board is bad. I am going to check the voltages on the blitz board, but havent figured out how yet. Any suggestions from here?
