Flashing light - no Apple TV
The Apple TV box just keeps flashing and won't turn off - even after I've unplugged it, and the TV. Won't respond to the remote - if I hold down menu button it will stop flashing, but as soon as I release button, flashing continues. All I have on the TV screen is the Apple logo. This all happened after I did an onscreen Apple update. What can I do to restore everything?
