The buttons on my Dish 21.1 remote for TV2 has become harder to push in the last couple of weeks. (The TV1 remote works fine). I've replaced all of the batteries in the TV2 remote, verified that the UHF Remote Antenna (on the back of the Vip 622 DVR) is secure and pointed straight up, and no obstructions are between the remote and the remote TV's sensor eye. The TV2 remote and the remote TV are in a different room, 20 feet away from the VIP 622 DVR. The distance from the TV2 remote and the remote TV is about 10 feet. I've chatted an Dish agent and he suggested buying a UHF remote antenna extender and a coax cable. (The TV2 remote worked fine up to a couple of weeks ago so why would that be needed now?) Does anyone have any suggestions.
