Thought I’d post this to potentially help someone in the future. My MM colordmd started going out, would work sometimes, then go blank after being on for 30 minutes give or take. I went through colordmd’s support page (excellent), the dmd was getting proper voltage, had correct software version, the “Done” light stayed on after the dmd booted. The next step was to reseat both sides of the 40-pin blue LVDS cable on the DMD. Cleaned the 40-pin connection, and reseated the cables. Voila! Good to go...
