Question about Canon PIXMA MP780 All-In-One InkJet Printer
I have tried a different outlet and a different power cord. I suspect the power supply is bad. What do you suggest?
This is what the service manual says;
(1) Check the power cord
(2) Check the connection between
the SPCNT board (JPSU1) and
power supply unit.
(3) Replace the power supply unit.
