Just went to swop over a spare pin2dmd into my tftc and having a strange issue where after it comes on fine with colour files but after 10 to 20 seconds, the display freezes for a few seconds then picks up where it left off with the colours gimped. So far I've tried a couple of sdcards without success, iam taking power from cn6. If I eliminate the card entirely and just set it to single colour mode it works fine. Any one had a similar issue?
