I believe the lights actually ARE the color DMD. Due to the size of it, the physical thing lights are removed and the color DMD is programmed to make thing light up.
Quoted from delt31:looking to replace the lights that are behind THING on the panel. What is the easiest way to reach these? Mine has a color dmd on it and it appears these lights are directly behind it. Seems like I need to remove the color DMD to replace? Before I went through the hassle just wanted to confirm.
