My Apple TV Gen 3 light just flashes expect when I press the main button on the remote then it goes out. There is nothing on my tv screen, except {NO SIGNAL}. I changed battery in remote and checked all connections.
Please unplug the Apple TV from the power for about 1 minute and then re-plug it in and re-test. If that does not help, it is possible the device may have failed. Before giving up, you can try the following too Reset or restore your Apple TV to its factory settings
The flashing light indicates the Apple TV is having an issue starting up.
If you have not done so, unplug it from power, wait 10 to 15 seconds, and plug it back in, and see if it starts up correctly.
If it continues to flash the light, you will need to restore it through iTunes on a computer: Restore your Apple TV through iTunes - Apple Support
