Went to a job today where we installed an MX-450 a couple years ago and the remote looks brand new but was dead. I inquired about it and was informed that it goes through batteries almost daily so it doesn't get used.

After putting fresh batteries in it noticed that it looks like pixels are burnt out but these change from screen to screen and in the setup of the remote the prev and next text never appears (thinking this is all related to each other).
