Update issue: Apple TV with ? over it

usually means that the boot device is not present or corrupt.
probably nothing you can do yourself to recover assuming you have already tried a reboot etc.

It usually means that the hard drive has crashed. If it happened during an update, it could mean that the update failed to install properly and created an unrecoverable error on the drive. In any case, if it's still under warranty, take it to an Apple store or call AppleCare.

At least it just crashed rather than having a hardware problem. If the update failed to install properly, you might want to do a factory restore first, then run the updater again. You'll have to re-sync it, but that might straighten out the problem.

if it's not booting then you won't be able to do a factory restore.

The OP said in his last entry that it started working again after he unplugged and replugged it, but wasn't clear as to whether or not the update successfully installed.
