I am having problems with an mx-880 remote. It has been working fine for approx 5 years. When I turn it on it starts just randomly sending commands and none of the functions are working correctly. I am also unable to get into system menu to reset. I have tried new battery, reprogramming several times with various different setups and nothing seems to help. I would appreciate it if anyone has any advice on what to else to try or does it sound like it just went bad. Thank you
