I bought a Zen from amazon and couldn't get it to work right out of the box, I got a replacement today, did a firmware update and was enjoying web radio for 30 minutes. Started hearing static, so I thought I would restart it. Now I can't get the large LEDs back lit. I am getting everything else, web radio works fine but I feel I have another faulty one. Anybody have suggestions? I created a support ticket. I have it connected to ethernet wire, how do I change settings so it streams using ethernet, not wireless? I don't see an option.
