Using Apple TV for the first time: STUMPED

Power and hdmi plugged in. There should be a white light infront that turns on.are you getting that?

Just having power on the unit is enough for the white led to appear. You may have to push the power cord harder into the receptacle on the AppleTV itself than you anticipated. If you don't have the power LED, do not pass go, do not collect $200.

I've had my ATV hooked up for all of half an hour but here's what happened to me. Plugged everything in, turned everything on, the TV said no signal from the HDMI input I knew I was using, the ATV's LED light went out after a minute or so, and I found the setup guide to be completely confusing. For some reason the thing that bugged me was that the remote had no effect on anything, so I used the instructions to pair it with the ATV by pressing and holding the remote's menu and >>< buttons for six seconds. The LED flashed and (I think) changed colors,the apple logo appeared on the screen, and I was good to go.

I hope that has something to do with your issue.

Is the TV on? I'm not sure it's even relevant, but if the TV is off, my ATV light goes out.

I just bought Apple TV today too, same exact problem you have. I plugged everything in, synced up the computer to do home sharing, turned on the television and nothing. It just keeps saying "no signal". The instructions don't say if the television should be turned to a specific channel or if it should be off cable (I turned the cable on and off trying to figure it out). I unplugged and replugged everything in and still nothing. I made sure the connection was as tight as it could since I read that could be an issue. The instructions just say to make sure that the television is on the "correct input" but I have no idea what that means. Usually I can figure anything out within a few minutes, but I'm coming up zero on this one. Seems like the instructions are missing a very crucial piece related to the television itself.

On your remote for the tv...should be a button that says imput. If you plugged your apple tv into hdmi slot 1 or 2 etc... Then hit imput(sometimes "source") and go to hdmi1 or the corresponding one.

If you plug it into a hdmi slot and it's on, the atv isn't going to just start to play on your tv. You have to be on the corresponding source or imput to where you plugged it in at.

Only thing I can think of, to the original post......have you tried a different hdmi cable. I bought one for my Xbox a few months ago and had to return it because it was bad. Just a thought.
