My zune won't turn on what should i do?

You can call 1-800-get-zune. Or you could also take it to geek squad, because they usually know what they are doing. It also comes down to what we're you doing, did you drop it? Get exposed to water? Or anything else like that? The zunes are really fragile in my opion and break easily like yours and sadly mine. I would have gone with an iPod but it didnt have the FM radio.
