Hi there,
My Canon PIXMA MP510 does not switch on anymore, nothing happens and no lights.
According to the service manual either the power supply board or the main board/logic board will be defective.
Between the power supply and the main board there is a 5 wire cable. According to the service manual this is the pinout:
J503
1 - Motor power supply, +32V (output)
2,4 - GND
3 - Head power supply, +24V (input)
5 - Power supply control signal (output)
N.B. The cable between power supply and logic board is in mirror view, so 1-2-3-4-5 on one side is 5-4-3-2-1 on the other side.
This is what I measure on the pins of the power supply unit, with the cable disconnected:
1 - 7.5V
3 - 10V
5 - 0V
I looks like the power supply is in "low power mode", because the control signal (pin 5) is 0V.
Any suggestion on how to solve this?
