My TV2 remote has stopped working. It has new batteries and worked this morning but now it does not. I went to the menu screen and changed the UHF address with no problem, but it will not change channels or anything else. I can change the volume on the TV using the remote. If I am in the menu screen where you change the address and press any button on the remote, it just makes the little #2 icon blink so I know that it is communicating with the receiver. Does anyone have any suggestions?
