Why does a sad face with online spport come on
Why does a sad face with online support come on when i try to power on

ANSWERS:

Logic board is fried ?. Not in my experience. On iPods with a hard drive this usually means the hard drive is knackered. I haven't seen it on flash based iPods.
This happens every now and then on my 4th gen iPod photo. I just open up the case and power it up again. Normally boots fine after this so I put it back together.
Before banging the drive, I would propose reseating the hard drive and its connector cable - just unplug and replug. I have been able to rescue iPods this way with nothing but a guitar pick. It's not necessarily a permanent fix, but it will get your iPod up and running for a while at least.
When a Sad face with an online support website comes on it means that your iPod logic board is fried and it cannot be used any more which means that you have to replace the logic board or go and buy another iPod
