Quoted from SantaSangre:
hi, need help. My WOZLE has a problem with the LED Boards (7,5 Volt, non-buffered). When they must display pure white, is flickering. All other colors are fine. Help!!!
In test mode, do they all display red, green, blue correctly? If NOT, then skip over the board that is displaying color incorrectly and take that board number off the list in settings (disable)
If they ARE showing the primary colors right, you will have to just jump over each board one at a time until you find the one causing the white to flicker problem. Start at board 2, disconnect the jumper to board 3. Is the white solid? reconnect the jumper and repeat that with board 3, then 4, then 5 etc until you find the board that makes the others flicker.
