I just .. got my fixed last week ..

They rarely go wrong ..  most the time, something is stucked inside.

First, turn it off, and see if there is a "FUSE" ..  and at the bottom, u should see a spot for "hex" key, (usually ~ 5mm) you just need to put a hex key, and manually rotate it, in order to move whatever out ..  you will surprise!

Then you can try to turn it on. (after take whatever out, my case, got a SPOON in it!)

90% time, it works.
