I received my Cardputer yesterday. When I turned it on, it chimed and the display lit up but only glowed, nothing on it. I thought it might need to be charged, so I charged it all night (with it ON so large battery would charge). When I turned it on this morning, the same thing happened except that, now, there are several different colored lines appearing at the top of the screen.

I've tried resetting the device several times with no luck. Is this a defective / broken display or is there something I can do to fix it?
