the best way is to try the search feature....Emerson tvs do not like comcast remotes... ive had a very low success rate. If its a combo emerson tv then i wouldnt even try.
This is for Red select button remote.
With TV on:
Hold down setup button while in TV mode till tv light blinks... Type in 9 9 1 then 1 again, press grey power button once then continue to press channel up button until the TV turns off. Hit setup to lock in the code.
DTA is the same except you just do 991 then start pressing channel up.
Go slow at first it is easy to skip past it and lock in the wrong code. If you press channel up for more then... lets say 2 min... then its not going to work.
Thank you so much - following the instructions above by hyatis found the code for my Emerson TV. I followed the Comcast remote manual I found online to then find out what the code is for future reference but that didn't work. But then again neither did the instructions it had to search for the code in the first place. At least it's working and I don't have the annoyance of using two remotes. Thanks again!
