Hi everyone! Need some help with my 72uvr. It's a 2006. I have installed a new power unit, I/O board, and new memory at the request of the dealer. When I start a print job the interface goes blank. It is still lit, but shows no words and the press just stops. Sometimes a 60 seconds into the job and other times it lasts 5 mins. To get it back up again I have to power it down and pop out the watch battery from the motherboard and re-power it up. Any help would be greatly appreciated.
