Tv sensor doesn't work

The TV sensors doesn't work and I need to know how to fix the problem. I know that it's not the remote control that is broken but it's the sensor light. I don't see the sensor light on the TV flashing whenever I use the remote. So my remote is useless.

Check the remote control for its infrared emission. Check it with fresh batteries. Check it by pressing all the keys. You can detect the presence of infra-red emission from the remote control, using a cell-phone camera. If you wish to get more details about how to check a remote control, please visit this site. One among the posts has details about it. In some cases, the remote control might need to clean.

SOURCE: the tv sensor is not working on my 42" lg lcd hdtv

Believe it or not...THIS WORKS!!!! 

 Look on the back of your set for an external remote jack. It should be the same size as a small headphone jack. If it has one, use a spare headphone plug or your headphones, and plug them in and out about 50 times. This will clean the tarnished contacts and make your remote sensor start working. Your remote sensor goes through a switch on this jack.

SOURCE: LG LCD TV won't respond to remote controllers

sparrow00, your fix worked for me, and I think I know why. The 1/8" remote input jack on the back of the TV has electrical contacts inside that are probably there to sense the presence of a plug-in remote. When they detect the insertion of this plug they disable the front panel IR (infrared) receiver and the TV only responds to this plugged-in remote and the buttons on the TV itself. After some period of time these contacts get corroded and the circuit is no longer completed between them. The TV now thinks an external remote is plugged in, and it ignores its own front panel IR receiver.

When you plug a 1/8" plug into this remote socket on the back of the TV it wipes away the corrosion. When you remove the plug the internal contacts conduct properly again and the TV responds to its front panel IR receiver. For best results you should plug a 1/8" headphone plug into this remote jack and twist it a few times, then pull it out and repeat several times. Repeat every frew months or whenever the TV acts up.
Thanks for your solution!

SOURCE: I have a tv (lg 32LG30) but the remote control is

First, check your batteries. Next, try using a small miniphone plug such as headphone and plug it into the remote sensor jack on the back, do that a couple of times to clean the contact switch inside, see if that will work first, if not, then you may have IR receiver board problem.

The TV stopped responding to the remote control


tried with reset doesn't work, ok it could be the IR sensor at the front panel of the tv doesn't work. but before you replace it you need to ensure if your remote controller is working. have you tried to check the remote with camera trick just to know if the remote controller is sending light to the IR sensor of the tv.

The sensor on the TV for the remote control seems to have stopped working


Hello,

If new batteries did not fix the problem, then it means the problem is either from the remote or the TV.

Remote: Check the remote battery terminal, see if its not rust. Also, disassemble the remote, can check the connection between the terminal and the remote board, see if there is no disconnection of any kind.

If after checking and all seems well, then it means the remote is defective. To confirm, borrow a remote, test it with the TV. If it works, then it means you need to replace your remote. But if the remote you borrowed does not work, then it means the problem is from the TV and not the remote.

TV: There is a sensor in the TV that communicates with the remote. If this sensor is defective, the remote won't communicate with the TV.

The TV sensor might have loosed contact from inside of the TV or it maybe defective and need to be replaced.

So do the above troubleshooting and let me know if the problem is from the TV or remote. If problem is from the remote, you need to do a replacement. But if otherwise, let me knows as well.

Good luck.

My tv control doesn't work and i put new battery's in and that didn't work either


There's a quick test you can do to test the functionality of the remote to make sure it isn't the TV's IR sensor that's broken. To perform the test all you need is the remote and a digital camera (cell phone cam works too). Take the remote and look at the IR "eye" through the camera's screen. Don't actually take a picture simply use the camera as you would a magnifying glass. While looking at the IR eye press a few buttons on the remote. If the remote is working you should see light coming out of the remote. Our eyes cant see the IR light but the camera can. If the remote doesn't light up then the remote is at fault. You can replace your remote on many websites for somewhere in the 20 - 50 dollar range.

http://www.replacementremotes.com/

Here for example, you need to input your TV model number and it will tell you what remote you need with pictures. Then, once you are sure that is the remote you want, you can order right from the same website.


Hope that helps!

The garage Remote control was working normally at first then for now reason now it just opens the garage door but doesn't close it. I checked the side sensors they look OK & clear, and I...


It could be the garage door motor that is acting up. Try closing it with the button in the garage. If that's not the case, you may need a different garage door opener.

It doesn't work


Hi,

is this a remote to TV or what? I am assuming it's a remote to a TV. If it is not for a TV, let me know, although, the solution is similar to any unit that uses remote control.

There are three possible causes for this problem;

1. Batteries may be dead inside the remote.
2. Remote might be defctive.
3. TV remote sensor/infrared might be defective.

Battries; Simply insert new batteries into the remote and try again. If changing batterises doesn't help, problem as to be from the Remote or TV's infrared.

Remote: Check the remote battery terminal, see if its not rust. Also, disassemble the remote, can check the connection between the terminal and the remote board, see if there is no disconnection of any kind.

If after checking and all seems well, then it means the remote is defective. To confirm, borrow a remote, test it with the TV. If it works, then it means you need to replace your remote. But if the remote you borrowed does not work, then it means the problem is from the TV and not the remote.

I am not getting any picture from the tv. dvd and radio is working fine.


press the AV button on the remote control & if it doesn't work, look for the TV button on the remote control; & if it doesn't work again, check the booklet that comes w/ the tv upon purchasing it or bring your tv to where you bought it & make use of the guaranty voucher for them to fix it for free, (try those buttons first before bringing it back to the store).
