Pixma Pro 9000 won't power on any more

Mar 28, 2020
Hi there,

Had a Pixma Pro 9000 for quite a while now (yeh i know, old, not the Mk II).

Suddenly won't power on any more. Have tested the PSU in a friends Mk2 and it powers his on ok, so not the PSU.

Tried using Control Panel to power on via USB but no good either.

Opened printer up, checked everything I can see, no blown resistors etc on any of the boards that I can see, no loose cabling, so a bit stumped what to look for next.

Any help greatly appreciated.
