32 gig 4th gen and the display went black.
I have a 32 gig 4th gen and the display went black while using it. I tried to rest it, but there is no display to see if it is even working. I plugged it into my laptop and it did start itunes. I just had the screen replaced by a local repair company. I called them and they suggested these two things. I plugged it into the charger, but with no display I can't tell if it is charging.
Dan for your error 1618, try this. "On Windows 7 or Vista, disable UAC in start>control panel>user accounts. restart PC. device disconnected, turn completely off. perform this procedure: open itunes. simultaniously connect cable and hold home button until itunes message "detected device in recovery mode" . acknowledge message, click restore." from here. Also turn off all anti-virus software as well as your firewall. Error 1618 can be caused by missing system files or corrupt data in iTunes installation. Try to uninstall iTunes, restart computer, install again. Also, iTunes tried to enter the Restore Mode, but the device turned back to the Recovery Mode. try something like TinyUmbrella and follow these steps. Hope this helps, good luck.
