This happened to me also after 2 weeks.

How long was there turn around?? I gave mine to my LHS and they sent it in. That was 2 weeks ago.
I bought a Novak setup becuase of there reputation. Now I dont think I will buy another Novak product.

I picked up a 9920 and 8XL and have not had any problems (except for too much power and breaking everything else).
