My Canon i865 printer no longer powers up after using a refurbished print head - the light on the power switch no longer comes on. I have tried my original print head and the printer still doesn't power up.
I have tried its power supply in my other printer (same model) and that powers up ok with it.
I suspect its blown something on the main board - the three ribbon cable sockets connect to the print head.
I have checked the fuse fu303 and it conducts.
I have attached photos of the front and back of the board. Unfortunately the service manual I have doesn't have a circuit diagram.
Thank you
