Having the same problem with mine. Works great for a few days then just quits working. Reset doesnt help. I changed the ribbon with the mill spec one from eBay due to a crack. Everything else works just sometimes the screen wont come out. Pulling the battery cable seams to fix it so I am at a loss as to where to look. I just leave mine set to manual so that it just stays out. Problem solved for now. Mine is a N1
