You have to check the remote control first, for its infrared emission, before confirming the infrared sensor inside the TV is defective. The LED you see lights up, when you push any button, is not a symptom of proper emission of infrared rays. Infrared rays comes from and infrared LED, fitted at the front end of the TV, and these rays are invisible to us. But you can check it, with a cellphone with camera option. If you wish to know more about how to check and repair a remote control, check the sites linked here.

Check the remote for its infrared emission first. Light up the LED at the top of the remote control, is not and indication that it works properly. The infrared LED is at its front end. Check it for emission. If you wish to get more details about how to check and repair a remote control, check the link sited bellow. If the remote control is OK, then the infrared sensor inside the TV is faulty. http://electronicshelponline.blogspot.com/ The infrared sensor will look somewhat like this, and can be located just behind the infrared reception window at the front panel of the TV. You have to open the TV to access it.
If you're asking about an infrared remote control then yes. It will work with the ML-L3 remote or equivalent. You will have to set the shooting mode to one of the two remote modes to do so.
If you're asking about taking infrared pictures then not so well. The camera has an infrared filter that masks out most infrared light from reaching the sensor. There are companies such as LifePixel which will remove the infrared filter to convert your camera into an infrared camera.
There is an easy way to check if the infrared light used by the remote to communicate with the television is working or not. All you need is a cell phone with a camera on it (or any camera). Cameras can detect infrared light that easily unlike our eyes which cannot see infrared light. Point the camera at the top of the remote where the infrared lights are. Press the power button on the remote and you will see the infrared light blink on for a second. If this is the case, you know the remote works. If not, you have a broken remote or one that needs to be fixed. I can help you a lot more if you provide the model of remote you have. Good luck!
the problem on your remote i think,, infrared is defective you can testing that by using digital camera place on the top view in the front of infrared of remote when you press any button on remote the infrared should lights on to the camera if not your infrared is defective you need to replace that thank you
You just check your remote control handset for its infrared emission. There is an infrared light emitting diode [LED], in front of your remote control handset from which infrared light rays are send to your TVs infrared sensor, fitted inside it, behind the infrared window on its front panel. Infrared rays are invisible to human eye. We can check if it is there by using a cellphone with camera option.
Put the cellphone in camera mode, and place your remote control's LED side towards its lens, for about a feet away or so, and when you push its each button, you can see an image in the phones' screen. If it is there, and still your TV don't work with remote control, TVs infrared sensor inside is faulty, and needs replacement.
If there is no infrared image from your remote control, you have to buy one new remote control. OK.
Generaly most night vision cameras are of the infrared kind where you need infrared lights of typically infrared LEDs.If you can get more infrared leds towards your objects will be better.Or you can buy infrared lamps with independent power and similar to the ones you place on your front yard.I've tried it and it works.
Here is another post that describes how to test to see if your IR emitters are working. In addition, it steps you through the process of replacing the emitters on the Harmony 880. Although you have a different model, you may be able to pick up a few tips from this article. Good luck!
