I have a lexmark 650 that had no display, but the fan above the fuser runs. I checked the power supply and all the outputs are there.
I ordered a system board and installed it and the same thing, however, if i enter the diagnostics mode while turning the power on,
holding the right and down keys, the display comes on and i can exit the disagnostics mode and the nprinter will work fine. Does
anyone have any ideas?
