A guy on Facebook was posting about the same issue. Here is his original post:
“Hey guys back to my Hook , the DMD resets during the game , I’ve repinned the connector at the power supply , still no change , what voltage is causing the reset , 5 v, or 12 v , I have not repinned the connector at the DMD yet”
Then just today he followed up with:
“Problem fixed ! Reflowed DMD header connector , replaced both ends of the power connector woohoo!”
