Answer to: Backlight Not Working, Possibly From HumiditySame thing happened to my 5thGen Nano. But guess what it wasn't the humidity. IT WAS THE LACK OF HUMIDITY The screen was just the way you described. And I had been using it that way for about a month THEN - I laid it on the edge of the tub one evening during my bath. I forgot about it and retrieved it the next day. There was a bit of moisture underneath, not inside. AND THE SCREEN WORKED! It's winter here, and humidity runs about 20% After a while, the screen stopped working again. So I simply blew gently my moist breath into the connector hole. For about a minuite - and VOLIA! It works! Who knew! You do now!
