Please check LG remote on another LG tv to confirm that remote function is fine.
Check volts with multimeter on IR sensor it should be 3.3V or 5V
If volts are fine then replace main board as Microprocessor on main board got defective.
Let me know if you have additional question.
Thanks.

If you are using a universal remote, I suggest re-programming it with LG remote codes; if it is factory remote I recommend resetting it to factory condition.

Unless you have a second LG 42LG50 television you can test the remote on, I am not sure how you can be sure the remote is functioning properly in TV-mode. But until you can confirm the remote is not sending valid TV control commands, I would be reluctant to advise you replace more parts in your TV.

I suggest taking the remote to a store that sells your model of TV if possible and trying it out there to be certain the problem is in your television before further TV part replacement.

I hope that helps.

Turn the TV off and then back on. Enter #0 #3 on the LG TV's remote and then push the OK button the remote.

Check on the back of the TV to see if you have a "remote in" port. It will look the same as a 3.5mm headphone jack. Unplug the TV and plug a pair of headphone into the port and then remove it. Do this several times to breakup any debris that may have gotten into it or corrosion that may have occurred in the port. If something is in the port it will disable the standard remote sensor on the TV.

Remote not recognized by TV. Brand new model.


An easy way to tell if the remote is bad or not and I know this sounds funny. Put the remote next to a small am radio tuned off a station if you hear a pulse when you press the buttons on remote it is ok 95 % of the time. If this set is new just simply call LG or get an authorized service center to replace IR sensor in TV.
