Mogul Issue: Boots Up with Black Screen

[XGuard04]

When my phone boots up it has a black screen. The phone boots up properly in terms of software since active sync can still connect to the phone. However I cannot view anything on the screen. I have tried reflashing the ROM (to the 3.56) and nothing has changed. I do not believe that I did anything to induce this behavior, it just happened this past night.

To all the many PPC geniuses out there, any insight on how to resolve this?

If no one can resolve, I would like to hear opinions on how the Touch Pro compares to the Mogul since I am now considering buying one (even though I should be upset with HTC at this point!)

Thanks.
