My iPod Classic has white screen.

This morning i wanted to turn it on, but it couldn't, so i thought it was discharged. it was already unusual as have all of my devises charged and clean all the time. When i came home it plugged it in to my MacBook Pro in hope to have it in proper order by the evening. But it didn't work and worse that that, the white screen appeared! I have tried all the steps that apple suggested, but it just wouldn't work! What to do? My Mac doesn't see the Ipod and the thing itself is completelly silent, nothing works apart from the screen.
