What is a MUX driver Alarm

Hi I am getting an alarm and it says Mux Driver alarm. What is a Mux Driver? I have just fitted a different Hopper as I cannot get one to work. Any ideas on this also?

It's a problem with the lamp multiplexing. Could be down to a problem with the main board (assuming this is the MPU4 tech machine?)

Thank you, yes I have since taken the board off and it is battery damage. I am trying to get a close up of the MPU4 battery tracks so that I can repair them, but my board has a small area of damage to the track and you cannot see where the tracks go.

I can probably find you a schematic, that should be even better?

Yes that would be great, thank you, but I doubt that it would make any sense to me, if it is the same as the one in the manual. I do not know why there isn't a area on here where such thing are permanently available. It would be so useful to everyone and take away the need to put on a repeat post or trawl through old ones.

Yeah I suppose a picture is better than a schematic in some ways, but you won't necessarily be able to see all the tracks.
I can take a photo of one of the boards that I have if you want?

hi, I have sorted it out. I cleaned off the circuit board and fitted a new battery and all works fine. Thanks again.
