Call HTC and send it back for warranty repair. My Flyer had a damaged LCD and we sent it to HTC and they repaired it for free.
I bought mine "open box" from Tech4Less in November, it was originally from Best Buy. It is worth a shot in my opinion. I figured mine was a long shot since I had no proof when and where I bought it from, but they fixed it anyways!
