Remote control seems to be working though only up close to the tv sensor (2centermeters away)but sometimes not at all. Have tried new batteries and purchased a new remote but still same problem.
SOURCE: Remote sensor on TV (LG 42PM1MA) seems to be broken.
Have the technician check for 5 volts on the remote IR Sensor if present the the Remote sensor has failed. Have him replace it to factory Spec's. No need to replace entire main board when the sensor is no more 5 dollars....
Testimonial: "Thanks a lot. Seems you've done this yourself :)"

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!

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 Step 4- Put the batteries back into the remote, being very careful to install them correctly. 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 this does not work then;
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!)
New batteries should be used if you're not sure about the old ones.
If you do then the problem might not be the remote but the sensor on the set.
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

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.
