So last night I manually installed the latest update. It was talking a long time, so I turned off the TV and let the little box do its thing. However today I tried to airplay something and noticed it wasn't showing up on the network. I attempted to to wake it with the remote, but nothing happened; no white LED and no picture on the screen. I tried unplugging and plugging it in after about 30 seconds. Nada. I tried using a different power cable. Still nothing. Finally I connected it to my computer to try and reset it using iTunes, but the program wasn't even able to detect it. Is there anything I could have missed?
