Facing TV Problems? Ask a TV Technician.
Hello, my name is Rusty. How did you reset AppleTV?
Ok, I want you to disconnect all of the cables, and press and hold the reset button for a full minute. Let it sit an additional minute. Plug it back in, and tell me if that fixes the problem.
Nothing on the TV?
Green is good, since it's changing, hit the reset button again. We may need to unplug it and let it sit for 30 minutes. Since the light is changing, it means something is working. They can get stuck from time to time and be a problem.
If you get frustrated and throw it out the window, I found a refurb for a great price, click here.
Try it once with the cables. If it doesn't change, disconnect everything. There is no wrong way, it's changing, and we just have to keep messing with it until it starts working again. If you get a green light, plug it directly into your TV for testing purposes.
