Any help would be much appreciated. My daughter has had her new EnV phone for just under 2 months. When she turned her phone on the screen went gray, then black and powered down. It will now not turn on.

She has taken the battery out and put it back in but still nothing when she turns it on. She indicates that she did not get it wet or drop it. Anyone have any advise, remedy etc. for a fix. We did not have insurance on the phone and all Verizon is willing to do is give us a refurbished phone. I'd rather fix the new one she has than end up with a used refurbished phone. Thank you in advance
