Did you try different power supplies? Adapter? Battery pack?

Activity for 1 sec, could be it testing for correct voltage at one or more locations in the circuitry.

Example, a short circuit will cause an error, and cause shutdown.

The problem will be difficult to diagnose.

Do you hear it beeping at any time? The number of beeps is a code telling what's wrong.
