Nano has blank screen

My generation 6 nano has a blank screen. At first I thought it was dead and went thru all the resets and so forth. According to my computer and iTunes, it should work. And it does, but the screen is dark, making navigation a joke. I don't pictures or videos on it, but lots of music. I guess I could learn to navigate in the blind, but is there a way I can get the screen to work, or has it given up the ghost?
