HTC Mogul screen not working

[itscrazy]

A couple of hours ago my screen just stopped turning on. All the lights work but when the screen turns on it stays black. I've reset it a billion times, took the battery out a few times, and checked the battery connections as well. It also takes a really long time for the buttons to light up when I press the power button. Before this started happening my screen would freeze when I turned it on.

anyone know what the problem could be and possible solution?

thanks!
