Grandis DVD player has suddenly stopped working
 

Hi
My roof mounted DVD player stopped working all of a sudden.
Kids swear they weren't messing with it!
The power button lights up red (but not blue as before)
And the screen flickers white to black.
No DVDs will play in it.
There is a whirring noise from it too.

Help really appreciated. Doing a long journey at weekend with kids and need it to work.
