Backlight Problem (Big Problem!! Please help!!)

[bgdv72]

I installed the HTC.Kaizer.Home.Plugin.with.Tabsetting.schen.

Just clicking around to see what things were I clicked on the 3rd icon over from the left in the default launcher section and my screen went black!! No matter what I do I can't figure out how to get the light back on. Yes, it's late and I'm apparently not as smart as I thought I was but . . . . . . . . help please!

Device is apparently still working. Can call out by pressing the phone button twice thus calling the last number dialed. Can communicate via active sync in the cradle. Just can't see my screen. I've soft reset the phone. I pulled the battery for about 5 minutes and restarted it. All to no avail. I really hope I haven't killed my phone. It appears I turned off the backlight so . . . . . . . really stupid question . . . . . how the heck do I turn it back on? I know it'll be something real simple so please let me have it!! Aaauuuggghhh!!!

Sorry for such a stupid first post but as you can probably tell, I'm kind of freaking out over here!!!!!!!!!!!!
