I have an Apple Tv both 2nd and 3rd generations. My vidoe is working but no sound when trying to play a video from my Iphone. I use Airport express for wi-fi. I am able to do everything else with Apple TV.
AppleTV 2, iOS 6.1.2
Welcome to the Apple Community.
Try the following steps, check whether things are working after each step where appropriate, before trying the next.
1. Check AirPlay is turned on on the Apple TV (turn it off and on if it already is)
2. Check that both devices are on the same network (Settings > Wifi, on the mobile device and Settings > General > Network, on the Apple TV).
3. Restart the Apple TV (Settings > General > Restart).
4. Restart the Apple TV by removing ALL the cables for 30 seconds.
5. Restart your router.
6. Restart your mobile device.
