I have an issue with the DMD. Sometimes it comes on and sometimes it doesn't. This was a very rare issue but seems to be occurying a lot lately. When it comes on now, you can get through a couple of games and then the display starts freezing or showing wierd numbers. This made me think its the ribbon cable. So when I unplug power and ribbon and not sure which one corrects it but it comes back. Sometimes neither will correct it.
Does this mean the DMD is bad or do I have some bad pins.
