Mogul Issue: Boots Up with Black Screen

[WitnessX]

Try this. Pop the keyboard out, and turn on the Mogul. Do you see any illumination, despite it being a black screen? If so, try this. With the Mogul in landscape mode - keyboard exposed, try bending it gently - gripped like you're going to snap it in half, seperating the keyboard from the screen. There's a chance the screen will suddenly work - do variations of what I've outlined.

This has happened to my Mogul. Sadly, it is hardware. It's time to upgrade. In a way, I think HTC builds their phone to function for 2-3 years, then it craps out on you so you can upgrade. :/
