You can heat up the shell with hair dryer (avoid the side where is driver cover)I'm not really sure how it failed, but it could be bad solder.
I'm also not that ready to purchase anything else from K's for the time being, after so many reports of driver failure. It just so happened that the overall physical built of their products are actually quite good and did not seem like the cause of those issues. Could be internal work or design that needs brushing up.
