Quoted from Drac:No I haven't contacted ColorDMD as it is fixable, just annoying. Yeah I was thinking maybe a dodgy batch or something but I bought the 6 DMDs 2 at a time over a period of a few months from recollection (3 x 2 screens separate orders).
Not sure I understand why you wouldn't contact ColorDMD First before a public investigation?? They are incredibly helpful people over there seems letting them know would be the first step.
