Radio Not Lighting Up

Hey guys, I've got a Pioneer DEH-P47DH unit in my car. Bought about 7 months ago, worked fine but now the faceplate won't light up. If you shine a flashlight on it, you can see the LCD screen working and can read it fine. None of the buttons light up either. Hoping this might be an easy fix or is it usually a sign of an old radio?

Thanks for any help and advice.
