Well, I am not sure if this was already advised by someone here, but: Have you also tried to swap the floppy drive cable? It is most unlikely that this cable becomes bad (how?), but try this.
Another question: Have the 840av been accelerated with a faster quarz? I know that the 840av has no PDS, but I have (this is just an example) a Q610 that I once accelerated with a 48mHz 68040 PDS card (made by the German firm "Formac") and: The floppy drives refuses to work when the accelerator card is on. About swapping the mobos to get a working floppy controller: The AV capabilities make the Q840av a "Cult" machine. So. Peter -- Quadlist is sponsored by <http://lowendmac.com/> and...
