Thank you for the information,
the remote that came with that tv is a very basic tv only remote, it is preprogrammed from the factory to operate your tv model only. It is not capable of operating any other devices, and does not require any programming of any kind.
If the remote is not operating the tv, you would first change the batteries. If that does not help, it points to a defective remote or faulty sensor in the tv
Lets try a quick test of the factory remote. Take the tv remote into a dim/dark room, and look at the infrared emitter at the front edge of the remote, as viewed through the DISPLAY (not the viewfinder) of a digital camera. A cell phone cam, web cam, security camera, etc will also work. Each time you press a button on the remote, you should see the emitter at the front light up, flash, or glow slightly. If you do, then the remote is functional. If you do not, then the remote is bad and would need to be replaced.
