only shows apple logo
hi, i have an ipod classic 120gb i was listening to it the otyher day when the battery died didnt think anything of it and put it on the docking station to charge. when i took it off the docking station it was really warm and it stayed with the battery charging logo on the screen but not showing as charging, this has happened before so i just reset it by pressing menu and the action button. when it reset itself it just showed the apple logo with the back light lit! i reset it again but this time it reset and just showed the apple logo with a dull screen. i have connected it to the computer but nothing happens even when i put it into disk mode! please help!
