Do not try to turn it on!
Unplug it immediately.

The power connnection is faulty internally. Open it up and visually inspect the various connection points. You should clearly see the blackened area where the connection is faulty.
It is possible to repair it yourself if you know how to solder cleanly. You may need a new cord or other wire assembly.
