Help!! Backlight = BLACK!?

[Synned]

Guys, this is the second tim
e this has happened.
I accidently hit a program on my launcher that shows the mogul with a bulb. Screen turns black. I plug it in to my computer, and the screen comes on.

I hit the button again, just to see if I can turn it off, and the screen goes black. Now I'm stuck with a black screen while plugged in or not.

How do I change the backlight settings without being on the damn phone? I really really really do not want to do another hard reset.
Is it possible to remotely edit the registry to change it?
Im pretty sure what happened is that on the screen where you change the brightness they are both turned all the way down, and now I'm screwed.
Soft reset does not help...
Thanks guys...i want to cry
Joe
