Touch Pro BLANK SCREEN!!??

[Mogulroonie]

Got my TP from Best Buy on 11-12, everything was purrrfect. Flashed Yay4Juggs latest rom one week ago, tonight was out and about with the family xmas shopping, went to make a call, and my screen was blank!? I did a soft reset, because I thought the phone had froze, due to the cold NYC air, but how could it, if it was under my toasty warm Sean John goose down?? Well, after the soft reset, the phone comes back on fully, I place it back in the holster, and continue enjoying the time with my family. About 45 minutes later, I go to make another call, screen is off , I hit the power button, doesn't come on AGAIN! BTW, I hit the power button the first the first time it happened. Sooooooo, I attempt another soft reset, and the screen doesn't come back on, after boot up! I know this isn't due to the custom rom right? Or could it be? Also, does anyone think Best Buy will allow me to exchange the phoneeven if it's 2 days past the 30 allowed?
