sam,
not sure if this will help but i had a similar situation with my 930. ever since i bought it, it had a distortion coming from the rear right speaker that seemed to disappear after an hour of use. i sent it back to the sony centre (where it was bought from) while still under guarantee and they said they couldn't find a fault. but lo and behold, there it was.
i convinced myself that it must be another part of my system. after checking every other part of my kit (and by this time, the sony guarantee had run out - nice), it had to be the amp. it went in to 2 independent electronic repair companies and each time it came back "there is no problem".
eventually, by accident, i found out what the problem was - the crackle only appeared if ALL the channels were running. the repair shops had obviously only hooked up the rear right speaker and there was therefore no crackle (i think that problem was to do with the power supply - a faulty capacitor or something). the repair shop rang sony who asked what the serial number was before faxing over a ready made modification sheet - obviously sony were aware of this problem but the sony centr where it originally went to had done nothing about it! the amp was fixed in 20 monutes for a small fee and has been a great performer ever since.
so, while this probably has nothing to do with your problem, it might be worth persisting and insisting that sony or whoever the repair shop is actually set up the amp and run it under home conditions - ie with all the channels running and not just the rears.
sorry about the rant but for over a year this problem bugged the hell out of me, yet everyone i took it to said there ws nothing wrong with the amp.
keep plugging away - someone will eventually listen to you!
