ok so my AFM has an issue. the driver board fried. so i installed a new board, which was simple. the game starts, plays, sound is great. my problem is that the DMD display board does light up. I have already taken the DMD out and installed it in another game and it works fine. changed out the ribbon cable. disconnected connectors and reconnected onto the boards.
i cant seem to find another audio/video board instock anywhere. any ideas as to what it might be? thank you in advance.

Check the voltage coming into the DMD. It need very specific voltges to operate. Pinwiki has detailed information.

did you put the ribbon cables back correctly. Make sure the red line goes on pin 1-2 on the Display driver board.

You need to do this. DMDs only operate with specific voltage. There are three key readings and a voltage difference between two of them that must be maintained.

Once you've tested the HV you may need to rebuild that section. If you need help, LMK and I can take care of it.
