You must press "set" button (with a pen), then press "tv" followed by the code you have and finally "enter". Regards

Did you install the batteries correctly?
Some remotes (Universal) need to be re-programed when you install new batteries.
Go to remotefinder.rca.com/default.aspx?site=rca for proper codes.

Try the command code switch. I recently had a similar problem when my remote suddenly stopped working. It worked fine one time but nothing the next time I tried it.

I checked the emitter with a digital camera and found it was not working. I did the remote reset (remove batteries and push all the buttons twice, reinsert batteries) and the emitter was now working. However, the remote would still not control the base unit. I did the remote base code reset (push power, volume and TV/DVD buttons together) but this did not help. I then checked the command code switch. This is a small three position slide switch located in the battery compartment on the remote. I slid the switch back and forth several times returning to the default number one setting where it was before. I did not change anything on the base unit but the remote now worked.

Hope this helps.

Remote sensor on the tv may not be working. Try using a camera by aiming the remote IR sensor of the remote control at the camera lens then press and hole any button and check if you see a flicker of light. If you do, the remote control is transmitting, if not, the remote control is not working. This will tell you if the remote sensor on the tv is not getting the signal from the remote control
