I recently had my part of my screen go bad and freezing of commands in the RF/IR mode. I called and spoke to service tech. I was nice and he was very nice. He said send in the remote and IR-6 for repair and new firmware. The IR-6 turned out to have no problem. The T2 had a new LCD replace, new firmware and who know what else. It cost $50 plus shipping for about $65 total. Now the remote works better than it ever did. I think the firmware made a differce. The remote is very responsive even in the RF mode. I may add a new T2+ when they come out.
