I never got an e-mail response from IESS, so I called them and they said they no longer work on the Sony units because they can't get parts. Yet the tuner manufacturer (Maxim) is still in business as far as I can tell, and still offers these tuners. I'll try to find out if they are available. If so, I'm going to ask one local shop I know of that does circuit board repair (they fixed the video board in my rear projection TV recently) if they would be willing to try this repair. If not, I may try Stanley's in Peoria. Do you have contact info for him, eea123?
