Randomly turning off. Fuy charged.

My projector turned off at random. It was plugged into the mains and had a fully charged led on. When I press the remote power button, the projector comes on, shows the splash screen, then turns off again. The unit is not overly hot, and loses what heat it does have very quickly.

I have used the projector sparingly since I received it. Perhaps on at most 15 occasions.

Can you explain what is happening?

Thank you.
