Had my 3 about as long. Never a problem! Is yours the only one acting up? Make sure all 3 wires are plugging into the receiver properly. If someone else runs yours, does it do the same thing? You try using someone elses and see if problem transfers to other receiver or is it just yours. I've heard of a couple of guys having to cut the bottoms of theirs out to resolder a broken wire but...If you can try another one with your receiver and all works well, then the problem lies within the transponder.
