Karma indeed. Have been reading several blogs from the USA and NZ and Sony take no responsibility at all and quite often when people get their consoles fixed, in USA, they don't even get theirs back instead they get a "reconditioned" console.
Yeah apart from ripping it apart to remove and replace the HD and giving it a good vacuum there isn't much, it last had a "service" 5 months ago. Does this occur in the newer models?
