I would check what settings the main power supply is at. 220 v or 240 or 200 etc.
I had a similar prob and it all related back to the main power supply setting.
I would work from that end first.
* also, have u checked the dmd in another DMD machine. My Royal Rumble had similar issues, we changed out the DMD and it never haoppened again.
Triple check DMD in another Pin n see what happens.
