Infrared sensor in TV caused remote control not to work. 

Here is a solution to try first before going down the replacement track. My remote wouldn't operate my Samsung 55" curved screen TV at all. It worked fine on my other Samsung TV and the other TV remote would not work on the curved screen. I went through all the usual reset procedures, replacing batteries, powering down the TV, resetting as best I could without the remote to use and nothing. I was ready to proceed with a repair or buying a new TV. Then I had one last thing I had not tried. I removed the power cord, removed all plugged in devices like a thumb drive ,a powered external 4TB drive and even the connection box this TV comes with. I held the power button on the TV on for 30 Seconds, then plugged the connection box back in but not the external 4GB hard drive. Powered up the TV and straight away it connected to the remote and all is back to normal. Now I am not sure which part of that procedure did the trick, but I am guessing that the only thing that was still live with power when I previously powered down was the 4TB external USB drive. Maybe somehow it was holding power to the internal TV USB system but as soon as I rebooted without it plugged it all went back to normal. I have since plugged the hard drive back in as I use it for recording TV programs and it is still working fine. This might just bean option for anyone else with similar issues to try.

Answered my question exactly. Thanks for the tip of checking the remote with the video camera. That worked like a dream. Now I know the repair is going to be on my TV. Not good news. I was just hoping for new batteries in the remote, but your video set me straight.

Problem solved! My tv downstairs (same brand) works and controls my tv upstairs. The original control stopped working on the tv but works on the one downstairs, lol

Have you ever worked on a directv receiver remote sensor?

Just got a free 2012 42" RCA from Craigslist. It will turn on and play great for hours. Then turn it off and it won't turn back on. I unplugged the power cord and reconnected and the remote turned the set on. Tried that again didn't work. Thought maybe a bad cord. But later figured it may be the on part of the sensor is dying. When it plays I can change volume and channels with no problem. Was going to try and manually turn it on but don't see a manual switch. I found that the remote for my 32" Vizio would also change the channels and turn the RCA off, but then have the problem of not wanting to turn back on. So I figured it was not the remote and must be the sensor is intermittently picking up the signal to turn on. What do you think?

Thanks for the video. But what if i don't have a similar IR sensor component, like you do, from a scrapped TV? There are literally dozens of IR sensor part numbers (TSOP, TSSP followed by designators for frequency range, voltage output) available... but which one do I need? I have yet to find a TV schematic that breaks it down to that component level.

Hi again i liked your video as I am back checking my ir sensor. i have checked voltage across the sensor and there is no real change. when i press the remote. It is a vestel power supply and main board 17MB08. Just not sure if any sensor will do.please advise

I have a Seiki tv that wont turn on with the remote control. It will turn on by pressing the power button on the tv itself. After i turn it on the remote works at it should i can change channels, volume, etcetera. The remote even turns the tv off when i press its power button but once it is off, it wont power it back on. I have and older model smartphone that has the capability to operate the tv set. It also wont power it on. But once i turn the tv on manually the smart phone is able operate the tv just like the remote control. Do you think it is the ir sensor on the tv itself that is bad?

Where we can buy this item, is this thing is available in any electronic store?

Hey man I have a Sharp Aquos LC-60UQ17U TV and I believe that my IR sensor went out is that hard to change? If it is not could you tell me a part number for the board or point mé in the right direction. Thanks 👍👍from me!

I have this LG bluray player that sometimes refuses to accept the signal from the remote and sometimes it accepts it normally. Like, one day it will not work at all, but leaving it for a few days it works as usual until at some point it just refuses further inputs. Is it possible for the sensor to "go bad" partially like that?

Very good information

Hi. Thank you for the instructional video, it confirmed my suspicions that my bulb is bad. Do you know of any good , step by step tutorials on this? 🙏

I have a tv that works fine but doesn’t respond to the remote, I checked the remote is fine, the ir sensor flashes when the tv it switched on but will not respond to the remote, would this require the small sensor on the board to be changed?

I did a factory reset on a Roku JVC tv and the remote won’t pair. It’s not the remote because I tried different remotes turned the tv on and off etc. The remote was working fine before I did the factory reset. The remote will only turn the tv on and off but won’t pair. Could that be the IR sensor. Thanks.

You mean you can use other IR sensors from other TV sets? I'm trying to find an IR sensor replacement board for Vizio 3642-0132-0189 and no one has it in stock. So can I just use another IR sensor component replacement and desolder the old one with that one and it will work? Thanks in advance.

I have 2 panasonic sa-ak520 the one I use has better sound quality but the IR sensor doesn’t work so I opened the other one and removed the circuit board that had the IR sensor and replaced it on the other one, at first it work but then stopped working, why when it was on the other stereo it never stopped working but when I moved it to the one I use it worked but stopped working now both don’t work, and I have a 3rd one that does work but I’m afraid ones making the swich it’ll work then stop

I have an Oculus quest VR headset which uses cameras to observe infrared light being emitted from the controls for hand positioning and that got me thinking. Is the infrared sensor inside of TVs also a digital camera? And if not then how does it observe the light?

i have a panasonic display that the remote stopped working for after i cleaned the remote button contacts. the remote emits light, and makes the display's green power light flicker, but all remote functions have ceased. could it be the sensor? or does the flickering power led indicate the sensor is working? thanks for the video.

Can i use another IR receiver from any device.. Or is there a specific one that i should use..! Ans if i used a different one from another device.. Will i have to change the remote control itself?

is it posible to simply unsolder these IR LEDs and to extend them with a cable from the board? What max cable length would u suggest? Will that resistance harm the range?

I have a Hitachi plasma that intermittently fails to see the remote. Seems like it starts working after the TV has been on for a while, but not always. I guess I'll just try replacing the sensor. I had one of those test strips when I used to repair photocopiers. I had such a hard time finding one on the internet, I thought I imagined it. Finally found one from MCM electronics.

I have lg 40 inches the sensor is not working Can i change ir sensor with another even if it's not lg?

Good morning! I checked my remote control with the camera and it was working fine. My Tv remote sensor stopped working after using Note 3 Peel remote. Can you tell me what caused it?

please help me where to buy IR sensor for devant Model no. 32DL 541

Hi, I have a Sylvania 4K TV. It's not a Smart TV or anything, just a 4K. I try to use the remote and it doesn't work. The TV appears to be getting a signal from the remote, as the small power light at the bottom right corner of the TV (which is normally a solid blue when powered on) will flicker red as if there is communication going on, yet the TV doesn't respond to any commands pressed on the remote. Any ideas?

Hi there, I am attempting to replace the IR sensor on my Samsung Smart TV model # UN65F7050AF. I have removed the back panel but am not sure where the IR sensor is located. Can you please tell me where/how I can find the IR sensor? Thanks so much!

Not all cameras can pick up the light,I got nothing on iPhone 7 checked with an old Nokia and it was working

Thanks for this video. I have a number of remotes that work and the IR receiver responds. However it repeats the input indefinitely. e.g. if I press volume up once, it will go up, step by step to max, ditto for vol down. channel up one scrolls through all channels until I press OK when it stops - but that is difficult to use. I have this on one of my TVs and also on a friends TV.

Thank you i may have this issue

Remote is fine with the camera test! So sensor went bad on the TV is my guess, is that going to be an expensive fix?

hey bro , my remote is not working , the light is blinking on the remote, but still no reaction on the tv, if i use an other remote the tv functions very well, the problem is in the remote, any idea how to fix it ? thank u

I've got a power supply for a surround system that failed by bad caps. Replaced ALL of them and everything but the -27 rail for the display came back. The transformer is whining like it won't start or something and I'm getting 37v on the output of the transformer. Anything you can think of that could be causing it?

I can see the infrared in my remote without using a camera though. Is that normal?

Are sensors universal?

Is that tv I.r works as secret camera ?????

Hi, Thanks for this video. You passed on some good information. I do have a question, though. I've got a 32" LCD Olevia TV that was abandoned outside my apartment. It has a very nice picture and sounds great. No remote control, so I tried using a universal remote control, but it didn't work. I believe the remote control sensor is not working. When I get inside this TV, is there a part number on these sensors where I can order another one on Ebay, Mouser or Digi Key? Thanks, Tom

Hi, I have Samsung LCD connected to setup box of GTPL When I increase the volume by TV remote control it automatically decreases after some time. I don't understand where is the problem so please suggest me what's wrong with my TV. Thank you.

So a working remote not operating the tv is NEVER on the main board?

My Videocon welcome series 40 inch led tv has not catching remote sensor and not responding plz help WT to do

What is the usual voltage sent through those sensors?

can you send me some idea for my samsung smart tv remote does not engae with tv replace the remote with new sensor joy stick is bad need to replace it sensor board model is Samsung model un65f100afxa. i would greatly appreicate

Hello Buddy, my question is: how to differentiate between my remote being the problem or my TV infrared receiver being the problem..? I have opened the remote, cleaned it, replaced the batteries, tested it using my cell phone and discovered that only 80% of the buttons work on the remote. That said, when I power-up the TV using the side keys placed on the actual unit itself and then try to get a response using the remote, it's totally unresponsive! Do all the remote buttons need to work for it to be able to control my TV or is this a clear case of the problem being my actual TV receiver? I look forward to your reply, thank you.

Thanks Dave. I use my cell phone camera to see if they work.

Some while ago i remove a black sticker infront of the sensor and its not responding to my remote anymore whats that sticker called ?

Why does a camera pick up the infrared light?

Very nice, I will have to find one of those infrared cardboard testers.

Do you think I can change this...to fix my tv it’s gonna cost HALF of what the tv cost-EXPENSIVE!

I have an air conditioner that won't respond to remote control till the remote controller is brought very close to the sensor, almost touching it. I'm sure the remote controller is fine, but the air conditioner only responds to it when it is very close. Please what could be the problem? Is the receiver weak or what?

Grants Pass isn't going to click with most viewers to determine if your local. I would make it Grants Pass, OR if you can change your name. Nice video though, thanks. I did not realize I would need a camera to see the light. I trashed a remote control seller and now realize I might be wrong and it's the tv.

Good morning sir mere led me remote kam nahi kar raha hai aur usme 4 pin ka sensar laga hai mai ek karigar hu upay bataiye

Thx dude it helped a lot !!!!

Sir mera TV automatically apne aap hi operate ho raha hai like apne aap hi voice km ho rahi hai apne aap hi brightness km ho rahi hai
