I have an MK4 board that does not work. It came in a dedicated mk4 cabinet but the guy I purchased the machine from said that his transformer quit and when he replaced it that the MK4 board never worked again
He had replaced the board with a mk3 pcb and it was working fine (till i mess up the montor).
I tried the MK4 board in my mk3 Cab but cant get any picture or sound anything. (the 4 LEDs on the board light up but no video to my screan just grey flickering. No sound either)
Any Ideas on checking or is there anyone that can repair this pcb? or at least test and let me know if it the cabinet or the board that is a mess?
the pic below is a pic of the board and the marker is pointing out the 4 leds that light up
