I've used California Precision Service several times and they are a GREAT facility, don't let the outside fool you, it is a very unassuming building but they have the right parts, tools and people working there.
Thanks for the info! However, Cupetino is quite a distance from Sacramento. Hope to find something closer when I get out there in two weeks If not I'll bring it back with me.. I had a great experience repairing my d 7000 at Midstate here in RI !!
Not sure what it needs, but finding a replacement one may actually be more economical. There is one guy, Zack's in Providence, who I have met a few times in Photographica. He could tell you if repair or replacement makes more sense.
