Plug the unit it and leave it plugged in for a while, make sure to keep it off.

Let the power stay on the unit for a while, like 20 mins or so and then try it again.

I think that the unit has an internal battery like your alarm clock and when the power goes out the battery takes over. I beleive in your case the battery may be dead.

The same thing happened to mine.

Let me know.

Ticking sound

We have a similar problem which was from a bad coed to receiver connection.
Try holding the point to where you hear the 'tick' and wait for the connection.
