I have a pixma mx922 printer that was working fine then I went to print something else and the unit was powered off and have not been able to power on since. Im hoping it is just the power supply but would like to know for sure before I spend nearly 30.00 to purchase a new one. Also in the process of getting power supply open with out the proper bit i think I may have broken a small part of one circuit on the board. Maybe I can fix this with a jumper wire and maybe even fix this for a few dollars but more than anything I want to know if the ps is in fact my problem. Any help on where to test and what voltages I should get would be a great help. Going to post pics of this that should give info if not I can post the specs if pics are not clear enough.
