Hi All,
I am a complete newbie to this site - and to trying to test /repair PCB'S.
I have just stripped down my Canon pixma mp560 to replace the Ink Absorber pads - which on this model are really helpfully in the bottom case!
Anyway, I followed the official Canon Technician's Manual and Parts catalog, and did everything as per their instructions.
I did take precautions with the Logic board assembly as far as being grounded, and using an anti-static mat to put the board on, and then a AS bag to keep it in while I did the pads etc until reassemble time.
Unfortunately the printer does not power on - I get a flashing green led which then turns solid Amber. According to the manual the most likely cause is the logic board - Canon Part # QM3-5526-000.
I would just like to know if there is a simple way to test for any faulty components on the board - or more likely Is it fried?!
I have rechecked all the ribbon cables and other connectors to the board.
Any helpful advice will be appreciated - I am aware that a faulty print head can also be the culprit, but the same symptoms present with the print head removed.
Thanks
Jon
