[Electrical] 500 MFP M525dn Touchscreen stays completely Black

[fbkhan3]

Another one with strange issue with the printer in question. Sometimes when power on the
printer, the touchscreen stays completely black and This seems to happen completely random. When the screen works, it
will stay on until you restart the machine once again. Sometimes it can take hours, even days of restarting the machine to get the touchscreen working again. Sometimes we even have to unplug the machine for
hours in order for the touchscreen to start working again. Printer works fine though and I have no clue where to start? firmware upgrade, Screen replacement or will it lead to board replacement? Looking forward for your kind help...

Sound like a bad display. Is it on warranty? Start a case. If not you'll have to get one. If the display was blank I would say memory.
Also yea I would take the formatter and connectors and removable memory ,HD and reseat everything first. But the way it comes on and off says to me its the display PWB.

Have replaced it with another working display from another 500 M575 and for the time being it seems like fixed... I'll keep it under observation for one or two days just to make sure. Thanks a billion Wild Bill

It was Display Issue, Replaced it with new one and it worked like charm.. M575 and M525 have identical display (Touch Screens).
