My Go50 won't switch on.

I have charged it for 24 hours. When I connect the cable, the Tom Tom logo appears, a white line goes from left to right across the bottom of the screen and then the screen dies. So I can't even perform a reset. I am staggered that I can't contact Tom Tom to seek support. I just keep finding the same 'solution' pages that get me nowhere. Help!
