Giving a belated shoutout to Buffett. He has rebuilt about 6 or so K7000's over the past year for me, when I get an issue that I either can't tackle or don't have the time to figure out. He does good work, and the boards are shipped back promptly, and in working condition.
If you have a bum K7000, don't hesitate to send it to Buffett.
