canon pixma ip7250 dead
My Canon Pixma IP7250 just died no power. I have tested the main power lead works fine on other equipment. So as the SM PSU is easily removed by un-clipping two clips unplugged the 5 pin op plug, Switched mode PSU in separate plastic box, undone the one security screw pop open the cover and minding not to touch the 400v cap, as might be charged, discharged the cap, finding 3 fuses all OK 1 on the mains I/P 1 on each O/P all other components on the 2 PCB’s intact no pop-ed caps etc, Powered up the PSU and all OK. Replaced PSU. Powered up, Printer Still dead. Any One got what to do next ?
