Cannot program a comcast digital adapter remote to a RCA led tv/dvd combo, RLDEDV3255-A-E

We have searched the internet looking for the right code. We have enter all the recommended codes and we have done the "no code option" on the remote.  Nothing has worked for power and volume.  Channel changing is working.  We need help before we send back this TV.
