Nokia lumia 820 not responding

Try resetting it pressing and holding the Power and Volume Down keys simultaneously until the phone vibrates. Release and the phone should restart. 

You may need to reset to factory settings but this will erase all data stored on the phone.

1. Make sure the charger is disconnected, and switch the phone off.
2. Press and hold the volume down key, and connect the charger. An exclamation mark (!) is shown on the screen.
3. Press the keys in the following order: volume up, volume down, power, and volume down. Your phone resets, and boots up. This may take several minutes. If there is still a problem you may have to have the phone repaired.

If jonsie's workaround does not work then perhaps seek assistance from a Nokia Care Point.

You'll have to do a complete reset. I can't post any links at the moment but you will find the process if you google "lumia 820 hard reset"
