AT&T remotes not working
I have a Dynex TV and the three remotes that I have laying around don't work. They are 2 S10 S3 and 1 S30S1A. I can't seem to program them. They don't seem to work my TV at all. The other remote I have which is a S10 S3 works and it works my LG TV. I don't know what's wrong. I have followed the instructions exactly. Do I need a new ATT remote?
