During regular software update (prompted by Apple) which was progressing normally to ïnstalling"phase, the power to Apple TV and the Samsung TV were both turned off for 10 seconds. Now the Apple TV refuses to respond to any commands from the Remote and the yellow LED flashes rapidly. Tried turning both off for 30 seconds and then on again with no change. Initially a picture of an HDMI cable and the iTunes symbol came up on the TV set but this meant little to me and my Apple Tv does not appear in my list of items on iTunes.
If you accidentally turned off the power during the update installation you have probablycorrupted the firmware installation.
Assuming the update failed not hardware, then by using a USB to microUSB lead (that Apple annoyingly don't include!), try to restore the AppleTV software to current version software using instructions here:
