Picked up one of these at a garage sale. It will power up but I can't move around in the menus. Looking more closely, I found one of the gland nuts holding the connector loose, and the other cross threaded such that the connector turns. So, it seems that somebody has tried to open this, or else the original assembler was having a bad day. I took out the stainless allen screw in the center of the back but it's not obvious what it does. I can cut the jammed, cross-threaded nut off, but will I be able to open the case or are the halves bonded together?
