It came with two remotes. The big one with the display screen just stopped operating the receiver or TV or DirecTV receiver. There's a 'mini' remote for the receiver that does the basics, and it works fine. Yes, I tried batteries. The LCD and backlighting works fine. I feel like there's a 'mode' I accidentally changed or something. I tried the two different codes listed and neither of those worked. The receiver operates from the mini remote, so the problem is in the main remote.
Ideas?
