I have a 211 receiver with a Sanyo LCD tv. The remote that came with the receiver would just stop working for no apparent reason. Dish sent new remote that eventually did the same thing. Dish sent a different type of remote that eventually did the exact same thing. Dish then sent a IR to UHF upgrade kit, operator at Dish said some lcd backlights interfere with the IR response. That sounded like a reasonable explanation. But the remote still randomly does not respond. Now they have replaced my receiver and guess what, the remote (ir to uhf kit) still has response issues. Any clue as to what is causing and how to fix it?
