Question about LG 42LC2D 42 in. LCD HDTV
My TV doesn't respond to any remotes, I've tried all of the other solutions involving remotes and I know that it needs a new IR remote sensor. I have already ordered a new IR remote sensor, all I want to know is if it is easy enough to replace the sensor for someone who doesn't have a lot of experience with this kind of stuff to do; and/or preferably how to do it.
My LG TV stopped responding to the remote. A very helpful repair technician told me to stick a head phone jack in the sensor jack on the back of the TV a few times to clean out the contacts. Now the remote control works fine.

My LG 42LC2D remote sensor stopped working too. Seems common. I unplugged the TV and took batteries out of the remote. Also plugged in a headphone jack into remote control jack on the rear of the TV, as one person suggested. Voila, that's all it took. Saved me hundreds of dollars and a big headache.

As unlikely as it seems it ACTUALLY works. Plug in ANY 1/8" headphones to the "REMOTE IN" jack and then unplug the unit for 30 seconds, then replug and the remote worked. Not sure why but it works.

I would like to thank all of you for posting this solution as it certainly worked for me as well on my 47LG70 LCD TV. I proceeded to thoroughly dust all of the component input/outputs on the TV with an
air-can. The remote works fine and I do not need to keep the headphones
I'd been racking my brain trying to fix this problem; I even switched out remote control sensor board. I couldn't understand why the remote controls weren't working, but this solution, which seems completely irrelevant worked. Who would have guessed!!!

I had the exact same problem. Came across this site and the solution and it worked!! I unplugged the tv, used compressed air to blow the remote in opening, then plugged my headphones in (this only being needed to clean it). Now works perfectly. Great tip, thanks to whoever came up with this.

This is amazing. I have a two year old 32LC7D which is discontinued now. I have been having remote control issues not receiving the signal. I tried the head phone jack trick in REMOTE IN, and it totally worked. The LG phone support wanted me to call a technician and pay $$$$$$$ for a service call, or buy a new TV.

Glad my wife found this post. I would not have thought of this, it is so stupid but explains some other issues. I can guess the cause being a former electronics designer.
When the extenal remote connection is active it liekly disconnects the IR sensor input. For some reason this model is prone to false detection of the jack plug. When you plug in the jack for real and remove it, it clears the false detection. This could be hardware issue but likely is some buggy logic in either the hardware or some chip software.

Plugging my headphones into the remote control input on the back of my tv worked for me.

Our LG 37" suddenly wouldn't turn on with any remote or let us adjust the volume. We read on here that spraying cleaning duster into the audio input jacks would solve the problem. We took the TV off the bracket and sprayed directly into all the jacks and the put it back on the wall. When we plugged it in, it worked!!! Wow!! Give it a try, it only took us 10 minutes!!!

My cable box remote wouldn\'t even work on this tv anymore. And guys I as skeptical as they come. But after reading what you guys suggested, I got my can of compressed air from my computer desk and sprayed it into the remote input jack as well as ones near it. And the gates opened up and the angels sang. THIS ACTUALLY WORKS!! Funny thing is, I stumbled on this website after I called the nearest LG repair center to tell them that I was bringing my TV in tomorrow. Whew, I just saved a 50 mile round trip and mega bucks. Thanks guys for all your help.

My LG LCD TV quite responding to any remotes. I tried the compressed air trick by blowing the compressed air into the headphone jack and plugging headphones in and out a few times. This seemed to do the trick. Thanks everyone for posting this I would have never known!!

Same thing - I tried the same old trick with a headphone jack and it worked. Cant believe my eyes

Tried the jack trick and it appeared to work but next day back to normal. nothing.

OMG, I can't believe the compressed air solution in the remote sensor jack really works!!! I actually need to thank the Best Buy sales person who found this web site and told me to give it a try. Just saved hundreds of dollars paying some tech. I don't care why but it is cool!!!
Thanks to whomever found it!

My 5 yr old Philips 42 in Plasma has been one of the best I have ever owned.No complaints until recently when after a storm my remote would not operate the TV.I checked the TROUBLESHOOTING guide and tried everything it suggested but nothing worked.THEN,I read something that caught my eye:the TV is never truly powered down UNLESS it is unplugged.Today's TV's are just like computed.Sometimes,you just have to re-boot so that is what I did.I un-plugged the TV and left it off about a minute and plugged it back in.It came on automatically and when I tried the remote>VIOLA!!! Maybe this will help someone I hope!

Wow, we were about to sell our 42" for $150 and just go buy a new one. Don't know how it works or what it did but don't really care. Thanx for the tip!

I really didn't believe that a solution so simple could solve this problem..... I have bought multiple universal replacement remotes, and finally a manufacturers' remote.....none worked. I took a can of duster, sprayed out and inserted a headphone jack into the IR remote outlet in the back and amazingly, IT WORKED!!!! What a simple solution for a potentially expensive problem.

I was skeptical at first but I figured may as well don't cost nothing to try. Slipped in the head phone jack and it works. So to whom ever thought of that THANK YOU!

My remote quite working on my LG 42LB5D set after the power outage of the June 28, 2012 derecho in Virginia. I just unplugged the set, put in the headphone plug in the remote jack, took it out, replugged the power and the remote started working again. Great solution. Thank you.

I have a 4 year old LG TV model # 42LC7D. Both the LG and DirecTV remotes quit working. I blew compressed air in to the remote sensor port and both remotes are working again. Thanks for the solution.

Does that fix work if you do not have the manufacturer remote? I have an universal remote.¿

I was panicked and desperate and shockingly enough this works!! Plug in your headphones into the back, power off any way you can and hold for a few seconds then turn back on and bam BAM BAM!

Call a tv company

It Worked!!! I used the headphones and the compressed air. Our electronics company told us there was no fix and we needed to buy a new TV. The a/v guys thought I was nuts when I had them dismount the tv so I could try it and it worked! They laughed about thinking how crazy I was, but now they have this knowledge.
