I installed a ColorDMD (LED) into my T2 and while the actual LED screen works I may have generated some sort of issue during the install such that the video output from the pin isn't working properly.
I know the LED works since I can view the ColorDMD menu. During the install I may have had the 16 pin connector reversed or have done "something" else incorrectly that made the game reboot a couple of times. To troubleshoot, I disconnected the ColorDMD and then reconnected the original DMD. At first, the original DMD displayed the graphics, albeit distorted, but after a machine reboot, no graphics at all.
Next, I tested the 16 pin ribbon cable, but it was fine. I don't see any blown fuses, either. Any suggestions out there?
