unfortunately E246 is associated with the Counter and serial number PCB. It is very hard to get canon to replace it as it has to be coded to your machine.
Possible but hard.

Oh dear. This is a very unusual fault. It is indicating a problem with the memory writing to the counter pcb.
Mmmmm first thing to do is take off the back cover and look at the main pcb's. Please remember to power down and remove power supply from machine first.
Any pcb that can be removed and re seated should be checked. check all conections to main boards ans replace the covers. Power up and see if it all comes back on. If not post another problem and I will try and help.
