Hi,Thank you for asking your question today. It would help us to know:How long ago did you purchase your TV?Alan, the first thing we will need to know is if the remote control is the problem or the remote receiver on the Tv is the problem.
Is this the original remote that came with the Tv you are trying to use?We're looking forward to hearing back from you soon!
I see you have gone offline before we had a chance to communicate so I will go ahead and give a simple way to test the remote hand unit, this is a way you can tell if the remote is working or if the receiver in the Tv is at fault. Using a digital camera or a camera on a cell phone. turn the camera on and then point the remote control at the camera lense about 12 inches from the camera, press the power on the remote as you watch the screen on the camera, you should see a white dot appear on the camera screen, it may be flashing. if you see the white light (dot) then the remote control is good and the problem is with the TV. If the white dot does not appear then remote is faulty and you will need to purchase a new remote. I am assuming you are using the original Tv remote and not a universal or generic programable one. if you need to purchase a new original remote they can be found here.
