19Jan2014 I have an Emerson ewt2721 with what appears to be a broken remote sensor. I don't have the mfg's remote. I was using my cable universal remote without any problems. I don't know what happened it worked before and I can't think of any changes. The code is correct. I suspect the TV's sensor is broken. I am not able to access the TV’s panel and need to use a remote to operate the set.
