If the remote control is its original one; no set-up is necessary. Check the remote control for its infra-red emission. Check it with fresh batteries. Check by pressing all the buttons on it; and see whether all of it generates infrared signal while pressing. If it is found OK, check and replace the infrared sensor inside the TV. If you wish to get some details; check the site linked here. It has details about how to check a remote control; by one among the post. Surf the site with patience.

Hi, First you need to make a test to adjust your headphones wireless system.. .pls follow the step below:
"Connect the headphone base" TO " headphones
output of TV" with 3.5mm stereo headphone jack cable (than Tv should
mute ) Infra red headphone pilot lamp should flicker in parallel to voice coming from TV
Infra red headphone should have a rotary adjustment on it.. "Volume" adjustment
while TV talking , when you sit in front of the Infra red headphone (it works point-to-point ) you will hear the voice of TV, than adjust volume properly...Thats it..now lets go to second step..
Your headphone's Base should either "3.5mm stereo headphone jack" or "RCA Stereo jacks" or "bot"h..After completion of this test ,I recommend you to
switch / use "RCA Audio output plugs-white/Red cable " on the back of
TV instead of TV's headphone output ,since it mutes the whole sound..RCA
output plugs of TV work independently from the TV's master volume control..of course you need RCA cable to connect this..
Hope this helps!..if more help requires pls let me know. Take care and please Remember to rate/vote and give me 4 Thumbs Up for me to continue for Helping out the Community :)
you need to check the battery contact with the battery terminal make sure that the terminal is clean.
check open the cover of your remote and check the solder of the battery
terminal from the pcb board use a soldering iron resolder it.
using your cellphone camera test the infra red emmision of your remote
control aim the camera to the infra red of your remote.you must see at
the screen of the camera that the infra red is lit when any button is
pressed..if not the infra red is busted.
using your cellphone camera again to test the infra red emmision of your TV. Aim the camera to the infra red of your TV.you must see at
the screen of the camera that the infra red is illuminating.if not the infra red sensor of the TV is busted.
