iPod video 60gb: RESTART DOESN'T WORK. help me

Hello
I've been trying to update my iPod video 60gb. Clicked Update in programm, progress bar showed me that installation of update is finished. Tryed to close updater - it said I am to wait. After 15 min waiting I disconnected ipod from its cradle. Than I saw Apple logotype and after - this icon: http://a248.e.akamai.net/7/248/51/939361142595235/www.info.apple.com/images/kbase/93936/93936_7.jpg

here is the description of this icon: http://docs.info.apple.com/article.html?artnum=93936


After that icon, iPod switched off and never showed alive
Tryed to RESET device, switched Hold on and off, and pressed Menu with Select for some seconds. iPod is not reacting and just showing nothing on its screen. Tryed to reset many many many times. Nothing.

Computer cannot see iPod, coz it is just switched off and not switching on.
