Apple TV continuously flashing light
I'm trying to upgrade the software on my old Apple TV. It is saying that it can't detect the cable, but it was fine before I did the software upgrade. Now the Apple TV Unit has a continuously flashing light, and the TV shows it's "plugged in" but the remote buttons are not response. I have already:
- unplugged the device from the TV, left it for half and hour, and plugged it all back in
- held down the menu and down arrow to do a reset
- held down the menu and play button to do a reset
- held down the play and down arrow to do a reset
Right now, it's still flashing. I've tried plugging it into my computer and opening iTunes, but the device isn't seen.
Any suggestions on what ELSE I can try and do? It's a second veneration (old) Apple TV. Was super excited to see it connected find to the TV and it was about to start working until I did the software update.
What next, or what else, can I do?
