I wanted to try using a different power source other than usb and found a Dc input lying around and plugged it in. The input screen lit up for a few seconds, a few of the buttons flickered as well as one of the pads before going blank. I then tried to turn it on again, but it wouldn't work. I then tried plugging it in normally through my computer like I always do and it still doesn't show any signs of power. I then looked at the Dc input and realized it was a 12v instead of 5, and 1A instead of .5A. I am afraid that I short circuited my Keylab and that it is done for good. Is there anything I can do?
