I sent out an email to the Hana service department and I am awaiting a response. As for now, I wanted to see if there's something that I can do to fix something that might be minor. I purchased the Hana V200 on Sept. 2 from Hyperion in Illinois and it stop working today. All it does is briefly display Evolv DNA200 when I press the fire button and when i press it again nothing happens till i let it rest for a little. After sitting for a little it would repeat the process again. I tried hooking it up to my computer, but neither the computer nor escribe would detect the device. I'm not sure if my fuse is popped, bad battery and/or bad board. Any advice would be recommended. Thanks!
