General Dish Network would be an appropriate Forum since it can happen to all UHF receivers. Any neighbor can control your TV2 if their remote is set to the same address as yours. Your remote may also be controlling their receiver. Get the receiver to the System Info screen (try to NOT use your TV2 remote to avoid getting the neighbor's receiver to the Info screen as well). It will likely show 2 for the TV2 remote address on that screen. Push and hold the Sat button on the TV2 remote until the other lights blink, pick a new Remote address such as 6, 12, ... and then push # and then Record button. The TV2 address should change to whatever address you picked and the neighbor shouldn't effect your receiver any longer.
