Screen randomly turning off/on constantly

Hello All, I'm hoping to get some suggestions on an issue I am having. I just got a new Bionic from Verizon and the screen randomly starts flashing on and off (seems to only start when the screen is turned off...doesn't happen while I am using it). Sometimes it will stop on it's own after a minute or two and sometimes it will continue to do it until I hit the power button. While it's doing this the screen it not responsive and it will do it whether it is charging or not. It's stock and not rooted. Any ideas what's going on with it? Thanks for any help you can provide!

Sounds like a hardware issue. Take it back for a replacement.
