Customer has 2 that have blank display, but you can hear a fan when you turn it on. I went the usual route, replaced the control panel, still blank. Replaced the system board, still blank. By blank, I mean no illumination at all. The control panel came with new cables, which plug directly into the system board. I now have $600 worth of stuff in a dead printer and a very unhappy customer. The board and panel are married to the machine now and can't be used elsewhere. Anybody else had this?
