Hi xeroxer.
Thank you for using the Support Forum. Here is the solutions from the support page for your machine concerning blank screen. If none of these help please consider contacting your support centre for further assistance.
The control pannel of our Phaser 6360 printer is blank
(and poweroff/unplug doesn't help): do anybody know the
part number of the replacement part? I need the electronics
board under the LCD pannel.
