Question about Canon PIXMA MP830 All-In-One InkJet Printer
I'm guessing that the LCD will not light, because it thinks the scan lock is on. I have the lock unlocked, will not work. Bumped the printer so that the scan unit was all the way to the left, Locked and unlocked it. Still get alarm noise/light and no LCD.
That happens when the cpu on the main pcb does not boot, if all the plugs and cables are in, then you will need a new logic PCB. Could get expensive.
