My ColorDMD only displays one color.
Press the right button on the display to enter the menu system. On the first page, check the PRODUCT KEY. If the key shows up as KEY INVALID followed by eight blank spaces, the problem is that a correct key was not detected. The eight digit product key is unique to each ColorDMD board and can be entered manually. Instructions for obtaining and entering product keys are provided here.

If your product key is valid and shows eight digits, check to see if your display's ROM VERSION has been updated to a multicolor ROM from our SUPPORT page. If the version still shows SIGMA, this is the factory installed single-color ROM. Please download and install the game-specific multicolor ROM for your game using a USB drive. Instructions and a video demonstration for installing ROMs are provided on the SUPPORT page.

If the PRODUCT KEY and ROM VERSION are correct, check to make sure that the speaker panel display shield is clear and there is no colored film or gel inserted between the ColorDMD and the speaker panel.

Or go to the website and contact Randy.
