I’ve had my Congo for 2 years and it has played great for that entire time. A few weeks ago the dmd went out. The game plays, lights up, and even has sound. No display on the dmd. I checked the ribbon cables, swapped out another dmd, and even bought a new rottendog wpc-95 audio visual board to rectify the problem. It has not. My experience is limited at repairing and diagnosing pins. My expertise is in home construction. Any thoughts on where I should check next? Any and all help is appreciated!
