If you are in the Seattle Area, I would suggest to check out igsmwireless.com
I used to work with the owner in his past career (still my career), he does excellent work. I am unsure how available the parts are to fix it with it being so new.
Wow, sorry to hear about that. Agree, like someone else on another thread pointed out, the lack of accessories for the 928 doesn't make it seem like much of a hero device. I'm still waiting on a good case and armband to go with it.
I bought the Nokia cp-531 armband from amazon.co.uk for my Lumia 920 a few months ago. The site says it is currently not available now, but if you can find it online (not sold in US, but Amazon UK will ship here...others might as well), it is a great armband for the larger Lumias. Cases will be more of a problem since the 920 is not the same "shape" as the 928. It took a good 3-4 months before there were decent cases available for the 920, and even now it is hard to find them in brick and mortar stores
