A while ago I attempted to change the battery in my PRS 17C. While trying to loosen the battery clamp the head of one of the screws sheared off leaving the body of the screw still in the hole so the battery clamp now can't be used correctly. I don't know if it's related to my battery change attempt but one of the subdials doesn't work at all now. Would this movement be repairable or is it easier just to get a new one fitted? Is there anyone you could recommend to repair it?
Cheers.
