i have had my rti for sometime and it had worked flawlessly from the start, but now everything seems to be erased the only thing i can get to come up on the lcd is the main menu page [which is blank] and the control panel pages. the person who sold me the remote and did the programing is no longer in business so i cant get any help from him. anyone else have a problem like this? any answers as to why? can i reprogram it myself? thanks to all
