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: my MKJ40653802 remote won't work even after

This only takes about a minute and will restart 1 in 3 "Dead" Original Remote Controls.


Step 1- Pull the batteries out of the remote and leave them out until Step 4.

Step 2- Press and release each and every button one at a time on the remote control until every button has been pressed and released at least once!

Step 3- If your remote has slide switches, you must move the switch to
each position then repeat the button pushing in Step 2.
(When you're done, be sure to put the slide switch in the correct position to operate the unit the remote came with!)

Step 4- Put the batteries back into the remote, being very careful to install them correctly.
New batteries should be used if you're not sure about the old ones.

Step 5- Try the remote.

Special Note:

If you have a digital camera, camcorder or camera phone you can test the remote to see if it is emitting a signal. Face the remote towards the lens of the digital unit until you can see the front of the remote. Depress any button on the remote. You should see a light (steady, blink or flashing) being emitted from the remote. (no light means bad remote)
If you do then the problem might not be the remote but the sensor on the set.

IF this does not work then;
you can turn the set off and unplug for about an hour to allow any EPROMs to reset. Next plug back in and try the remote.
If this does not work it

SOURCE: The TV will not respond to the remote and

Hello,

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

You need to do some diagnosis to confirm the source of the problem.

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.

Regards.

Follow this procedure to troubleshoot if the TV does not respond to the supplied remote control.
  1. Remove the batteries from the remote control.
  2. Press each button on the remote control twice.
  3. Make sure none of the remote control buttons are jammed.
  4. Install fresh batteries into the remote control. IMPORTANT: Make sure the batteries are inserted in the (+ and -) direction shown inside the battery compartment.
  5. Make sure nothing is blocking the Infrared (IR) sensor on the TV. IMPORTANT: Some locations can interfere with the IR signal from the remote control. Glass enclosures, as well as fluorescent or halogen lights, may prevent the IR signal from reaching the TV.
  6. Point the remote control at the IR sensor of the TV.
  7. Press the POWER button and other buttons to test TV operation. IMPORTANT: Do not hold down the POWER button too long. Doing so may prevent the remote control from operating the TV.
    NOTES:
    • If some of the remote control buttons operate the TV but others do not, the remote control may need replaced.
    • If all of the remote control buttons work, no further troubleshooting is required. Otherwise, continue troubleshooting below.
  8. Try using the remote control at varying distances from the TV. IMPORTANT: Using the remote control too close or too far away may prevent the IR signal from reaching the TV.
  9. Turn the Light Sensor setting to OFF.
    1. On the TV itself, press the HOME button on the TV.
    2. Using the up arrow or down arrow select Preferences.
    3. Press the INPUT button.
    4. Press the up arrow or down arrow to select ECO.
    5. Press the INPUT button.
    6. Use the up arrow or down arrow to select Light Sensor.
    7. Press the INPUT button.
    8. Press the up arrow or down arrow to select OFF.
    9. Press the INPUT button.
  10. Power reset the TV.
  11. Make sure the TV has the latest system software (firmware) update installed, if applicable.
The troubleshooting steps above should resolve the issue. If you completed all the steps and the issue is not resolved, service may be required or the remote control may need replaced. Contact the Customer Experience Center at (239) 768-7547 to speak with a service representative for further assistance.

Tv volume control


Since it works when close, more likely the battery in the remote is running low, or you have some dust over the remote sensor on the front of the tv panel.

My television no longer accepts commands from the remote control. I have verified that the remote control works properly. Please advise.


Since remote control is verified so next thing involved in remote operation is remote sensor located on front of tv that receives remote signals.
Remote sensor seems defective in your tv and need to be replaced to solve remote issue.
Call local tv repairman if you have no experience of soldering parts in circuit board.
Thanks.

TV does not detect remote control.


Remote control receiving sensor circuit problem in the TV. Mostly due to degradation of the sensor over a period of time.

Go close to the TV and see whether you get a response. If it responds try determining the distance back wards. If the remote works up to certain distance, the problem is weak sensor (TV).

If totally not operative it is sensor circuit problem. It could be sensor or it's associated parts.

My tv remote doesnt work from a distance i have to go very close to my tv for it to work, i have changed the batteries though.


There are several possible reasons. The light-emitting end of the remote, or the remote sensor window on the TV, may be dirty. The light-emitting diodes in the remote may be misaligned from dropping the remote control, or they aren't putting out as much light as they should. The TV may have another light source shining on it that prevents it from picking up the remote signal until it gets very close. The remote sensor in the TV might be bad. Or there may be an interfering signal. As more people start using compact fluorescent lamps (CFLs) in their homes, they sometimes find that remote controls begin acting strangely. It's also possible the replacement batteries you put in are weak, so you might try another set.

Sorry I can't tell you which of these is most likely. I've seen them all many times. Try another set of batteries first, then try a universal remote to see if the problem is in the TV or the remote.

Good luck! Hope this helps, and thanks for using Fixya!

Dish IR Remote 20.0 has problems after sunset.


The problem for me was the TV giving off IR signals that interfered with DISH's poorly designed remote. When the TV's room ambient light sensor was turned on and it became dusk outside the DISH remote would stop working. Moving the receiver away from the TV helps but the problem is not eliminated until the light sensor is turned off.
Until DISH corrects this poor design there may be no other viable solution.
