Remote Sensor My remote control does not work the television anymore.  TV is less than 2 months old and the remote sensor has stopped working.  I have tried other remotes for tv, including LG dvd remote, and other universal remotes.  I believe it maybe the remote sensor.

I heard that LG TVs have a problem with the TV not responding to the remote control (there is nothing wrong with the remote control). Hopefully your TV is still under the 2 year warranty. Go to and report the problem. They told me that it's a common problem. They need to order the part and let me know when it comes in. (my TV is a LG 50PC1DRA)

The Akai TV might have LG guts inside.

Me again.  Just one more little note.  You don't normally see wire spring type contacts on the positive end in battery compartments.  There is usually a flat metal piece there that the positive end of the battery butts up against.  This is some kind of design flaw that probably accounts for A LOT of remote malfunctions with these Akai remotes.  You can still make them work though, with filing maintenance. 


Someone needs to contact the Akai people and let them know how dumb that is.  I'm sure the design is due to cheap wad considerations on their part in manufacturing.

I found the answer.  It's bad contacts inside the remote battery compartment.


I bought the Akai LCT3285TA 32" LCD TV from Radio Shack on sale for $699 in like April of 07.  So the TV has been running for around 6 months or so.  Recently the remote stopped working just like yours did.  So, the first thing I did of course was put in fresh Duracell batteries and discarded the cheapo Akai ones that came with the TV to see if that was it.  Still only worked sporadically. 


My symptoms:


1. Remote worked sporactically according to mysterious circumstances.


2. Even if I held the remote 1/2 inch from the remote sensor window it still wouldn't work.


3. Sometimes it would start working, but then if I like threw the remote up on the end table it would stop working.


At first it seemed to only work when I first turned the TV on with the manual controls on the side of the TV (WTF).  Then that stopped working.  After I changed to fresh batteries and it still only worked occaisionaly, I started supspedting the remote sensor inside the TV.  Then after more experimentation, I found that if I fiddled with the batteries a little and moved them around each time it stopped working, I could get it to work more often.  So that eliminated the remote sensor in the TV itself.  I was relieved at that.  I was thinking I had a $700 lemon on my hands. 


Well, I then checked the voltage on the new batteries with a voltage tester to make sure they were really good.  The AAA batteries are 1.5 volt batteries.  One read 1.58v (good) and the other read 1.56v (good).  So then I started looking at the contacts.  So I put on my magnifier glasses and the flater spring one of the contacts, not the long spring end but the positive side end, seemed to have some kind of brown substance up in or around the middle or center of the spring.  I got out a needle file and poked at it until I got rid of it and tried to file it a little to remove any possible rust or contamination.  The one battery that was in the same slot as the contact that had the little brown crap on it seemed to be a little pitted or messed up ta boot.  I then went ahead and filed both the tops of the positive ends of the batteries to make good fresh contact area there.  I then put the batteries back in and it's all good now.  Just like when I bought it.  I even slammed the remote around on my end table some and threw it across the floor a few times to test it to see if I could make it mess up and it doesn't fail now.  Bad contacts.  Could be that over time some kind of electrical shmigg gets built up on the contacts messing them up. 


Make sure your battery compartment contacts are smooth and clean.  File them a little (and/or your battery positive ends also) and make fresh contact area there.  It should get back to working like normal.  Yeah, don't go and buy that $100 universal remote on the Internet their peddling or that original manufacturer Akai remote that I saw being sold for $80 bucks!!

Remote is OK but TV logic model L22DVD W19 not working with remote came with TV which was stopped working after 6 months

Check the remote control for its infra-red emission. Check it with fresh batteries. If it is found OK, check and replace the infrared sensor inside the TV. If you wish to get some details; check the site linked here. It has details about how to check a remote control; by one among the post. Surf the site with patience. Pull up older posts. If the remote control is found OK; check and replace the infra-red sensor inside the TV. Contact any service technician.

The remote interface of the TV died on mine, it was intermittent then it stopped completely. Remote control is fine, it's the remote sensor in the TV itself.

The first possibility is that the new remote control is a dud out of the box. It can happen. Another possibility is that the remote sensor in the TV has failed. Then the remote is transmitting, but it's not being picked up by the TV. (The lights are on but there's nobody home.) If you can, return the new remote to the store and exchange it. Then, if the set still doesn't respond, you'll need to replace the remote sensor.

the fault is from your the TV sensor. Your remote sensor cannot sense the TV sensor, that's why the remote or any other cannot control your TV.

So its a remote sensor problem.

Take care.

TV scrolls through input sources on its own

To make sure the remote is still working, point the remote to the TV sensor, press couple of times and notice the Red LED is response or not. If the LED blinking, the remote works fine. The suspection now is the main board which is control all the inputs. You can try to get TV back to factory reset, it might help.

TV doesn't recognize any remote

The proble is the IR sensor 932220681667 or the small signal board. I would replace the IR sensor first. Also check the firmware and make sure it is BX23U- and if it is not go to and down load the firware on a USB stick. If the set still has the problem when both are done replace the small signal board.
