Owner never uses the monitor output. Main and monitor PA look the same
components but not mirror/same layouts. Any likely problems swapping the
simple screened leads from each preamp section and swapping the PA speaker
output leads?
Will then at least localise the problem to prea , if the problem recurs

Are you saying that the problem is only on the monitor output?
Doesn't the unit use both power amps in one mode, and one amp for main
speakers and the other amp for foldback speakers in monitor mode?

I would look at where the signal splits to the two separate power amps
and maybe test each power amp module with an external signal source.

Have a look at the slider pots on the graphic equalisers, they sometimes
get damaged in transit.
