Infrared receiver doesn't wokr

I have the same problem. Sensor doesn't work. Tried new batteries, cleaned the lens and a brand new universal remote. I took the remote to a TV repair shop to find out that the remote works. I'd have to replace the infrared receiver $75-$100. It's a Toshiba 13" with VCR, model MV13M2/W, 2002. I'd rather invest $100 in a new TV, but I'd prefer to get by with a cheaper fix. Is there possible?

Call Andrews Electronics and give the make, model number, and the circuuit board location (label printed in PCB next to IRreceiver). To check if your remote is transnmitting, point it a digital camera (cell phone camera will work just fine) and look at the screen on the camera while you press the buttons on the remote. The infrared light will appear as white on you camera display.

For that size TV we would charge about $115.00, if we did the work. With very little know how, you could do it yourself for way less than that.

Sharp aquos remote not working


Check the remote controls for its infra-red emission. Check them with fresh new batteries. If there is no infrared rays come out from its front window/LED; the remote control is faulty. If the remote controls are found OK, and the TV do not respond to it, the infrared sensor inside the TV is faulty; should be replaced.
Check the remote control for its infrared emission. Check it with fresh batteries. Check it by pressing all the keys. You can detect the presence of infra-red emission from the remote control, using a cell-phone camera. If you wish to get more details about how to check a remote control, please visit this site. One among the posts has details about it. Surf the site with patience. In some cases, the remote control might need to clean.

If you have to buy its original remote control, contact the authorized service centre, or authorized dealer to your device brand. They can either give you a genuine remote control to your device, or can direct you, from where can you purchase a suitable one.
To select a proper universal remote control, you should know about the number of digits to its set-up codes. There are 3 digit, 4 digit, 5 digit, 2 digit and even single digit codes, to some brand devices. After confirming this, check the sites linked here. Both the sites have set-up code list and set-up procedure to many popular brand remote controls. Check which brand remote control has set-up code/s to your device brand, and buy that one according to availability. Brand name of the remote control isn't a matter, but it should have set-up codes in its code list, to the device brand you have.
Please note: Every new universal remote control will have set-up code list, and set-up procedure along with its pack. Never accept a remote control, that hasn't both of this. For more details about the set-up codes, visit the sites.

Zenith tv, model #b27a11z. My remote stopped working with my tv. The remote lights up and the controls all work manually. I changed batteries, even got a universal remote with negative results. Its as...


Hi Keith,


First of all, thank you for posting your question here at Fixya.

My first advice is to confirm if the remote control is not the issue here and ensure that the fault came from the TV itself. Point directly your remote control's infrared emitter(Sensor) to your cellphone camera and then press any button key at the remote control, you will be able to see the flash of an infrared through your camera if the remote control is working fine. Watch the video below to have an idea how you gonna do this.



If you've confirmed that the remote control is not faulty, this is an indication that the problem is on the infrared receiver inside the TV. I would advice you to clean the TV's front panel infrared lens using a soft cloth, keep away all obstruction from the IR receiver, turn of the bright light in the room and check if the symptoms still persist. If yes, then the IR receiver inside the TV is already faulty and needs to replaced with a new one.

Remote won't work. Tried new batteries, reprogramming, etc. Universal Remote doesn't work either. LG #42PC5DC


Hi,
To confirmed if the remote control is working fine, aim the remote control sensor(IR emitter) directly to your cellphone camera. While pressing any button key on the remote control, you can see the flash of an infrared emitted by the remote control if it is working fine.


If you've confirmed that the remote control emitted an infrared but still the tv won't communicate with it, this is an indication of faulty IR sensor board of the TV. Check if there's an obstruction from the IR receiver in front. Keep away all of it, clean the plastic window of the IR receiver with soft clean cloth.
If the symptoms still persist, you have to replace the IR sensor board. Check the actual part no. of the board before ordering.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Tv remote not working


Hello
Check the remote control for its infrared emission first. You can check it with the help of a cellphone with camera. Eventhough human eye cannot detect infrared rays, electronic cameras can. Put your cellphone to camera mode, place the remote control [ replace its batteries with new ones]; at about one feet away from the camera lens, and press each button on the remote control. If infrared emission is there, you can see its image on the cellphome camera screen. If there is infrared emission for all button press of remote control; the infrared sensor inside your TV is faulty. It should be replaced with same type and number. If there is no infrared images, the remote control is not working, and should be replaced. Check the battery contacts of the remote battery compartment for any rust or dirt. Clean it well before replacing new batteries into it. OK.

No Remote control


A fairly common problem with these sets is that the connections to the IR receiver inside the set degrade. Quite often all that is required is a resoldering of the pins of the receiver. This is a 3 legegd part within a small metal box located near the fron of the TV. If you have no experience with TVs, do not attempt this. I would guess that a TV shop would be willing to resolder the pins on this for not much money. Call and ask. It might be a cheap fix for you. Cleaning the lens of the remote will have no effect.

Cant get remote for sharp 32 in to work new batteries in it not receiving


Is this the original Sharp remote or Universal remote controller? If you do not have a remote checker, you can verify if the remote is putting out any infrared signal by pointing at your digital camera lens, you should see flashing light on your digital camera screen. If it does put out signal, then it can be the IR receiver in the TV itself.

I'm afraid that the most likely culprit here is the infrared receiver inside the amp. Is this a new amp? If so, return it for an exchange.

No response from remote


Remote problem could arise from either tv or remote. First check your universal remote on some other tv and if it is okay your tv's infrared sensor has stopped working. You can get it from the local component shops, take the existing sensor with you. This problem could be from the micro processor in rare cases. Best of luck.

Infra Red LIGHT OUT


Hi, Based on your trying of different remotes, your conclusion is basically correct, however, it is very rare for the infrared receiver to go dead (or at least the sensor itself). Should this still be the case, there is no other way but to open the TV unit. Since the placement of the infrared receiver is to the front of the TV, chances are that what your are thinking "take the entire set apart." is the only way to do remove the infrared receiver. A guess would be the sensor which normally is available even in RadioShack. Your best bet may be to seek the services of a qualified professional willing to undertake component level repair rather than modular/PCB replacement. At times it may just be a loose connection inside the TV or no low B+ to the infrared receiver module/circuitry. Alternately, you can try to "borrow" an original remote and see if that will work just to really confirm. Some instances of this problem in some other brands/models got solved by resetting the TV (unplug for a couple of hours). Hope this be of some idea/help. Pls post back how things turned up or should you need further information. Good luck and kind regards.
