You might want to forget about getting it "fixed", as these are very problematic to have repaired. That's assuming you found someone to do it, and assuming they had any parts. If it were me, I'd consider it a 15 shot camera and be happy that it did that. Actually, that would be my second choice idea. The first would be to sell it while it's still pretty much working. One day, and that day could be tomorrow, you'll have a highly engineered and expensive door stop.
