iPod Touch - Screen not working?

Hi,

I have a 16g iPod touch which now isn't working;

Came to it just now after it had been on charge, picked it up and it just had a white screen. It was working fine earlier and hasn't been dropped or got wet etc. Google'd this and then tried to reset the iPod by holding the sleep/hold button and the home button simultaneously. The iPod did reset but now I have no screen at all, it doesn't even turn on.

The iPod is on however as when I connect it to my laptop it makes the connection sound and is recognized by my laptop.

Tried restoring it but that hasn't worked either.

Any ideas or is this the end for my iPod?
