Assuming it is an infra-red sensor with 3 legs, or 3 legs and 2 other legs as stands, you should be able to use any old 3 leg IR sensor.

If it s a 2 leg one, any other generic 2 leg IR recieve diode will do. With either type, you just need to get the device back in with the same leg configuration. it is usually marked on the circuit board

Tv doesn't pick up signal from remote

Hi Connie,

First of all, thank you for posting your question here at Fixya.
Please ensure that the battery is in good condition. Check the battery terminal for corrosion, Scratch it with fine sandpaper.
If the battery and its terminal is not the issue, please confirm if the remote control emits an infrared by pointing directly the sensor (infrared emitter) to your cellphone/digital camera. If it is working fine, you will be able to see the flash of the infrared through the screen of your camera. Watch the video below.

If you've confirmed that there's no infrared coming out from the remote control then this is an indication that the remote control itself is already faulty. Replace it with new one (part no. 0980-0305-3300 ).
If you can see the flash of the infrared, the IR board inside the TV is faulty. Please inquire at this link for replacement.

Hope I helped you.
Good luck and have a great day!

Tv remote not working

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.

Hi Expert, Both remote control did not work. The original came with TV and the Cable remote control. Thanks

If both remotes are not working with your tV, the infrared sensor inside your TV is faulty. It should be replaced with same type andnumber. Infrared sensor can be located just behind the infrared window on the front of your TV. It will be soldered direltly to a board, and can be detacted out from it. You have to open your TV, and locate this component. It will be in bronish black in colour and will have three solder terminals. The number will be printed on its body, either by ink or by laser print. Note the number, and it iis very inportant when you repalce it. OK.

How do you instal the ir reader in the is not reading the remote

The component you describes here is not the reader, it is calle the infrared sensor. It is three terminal component, can be located just behind the infrared sensor window of the set at its front panel. It will be soldered direltly to a panel board inside. To access it, you have to open the TV, locate the position of infrared window and there will be it. Just unscrew the board along with it, desolder it out from the board and go for a new one with the detached one as sample. It has a special number printed on it [laser printed]; and should be noted. Insist on same type and number, since it is a crtical component in your TV, although it is very small in size. It will look somthing browinish-black in colour, and can be bought from most of the electronics spareparts shops at your town. OK

My remote will not work the tv anymore


there are three possible causes for this problem;

1. Batteries may be dead inside the remote.
2. Remote might be defctive.
3. TV remote sensor/infrared might be defective.

Battries; Simply insert new batteries into the remote and try again. If changing batterises doesn't help, problem as to be from the Remote or TV's infrared.

Remote: Check the remote battery terminal, see if its not rust. Also, disassemble the remote, can check the connection between the terminal and the remote board, see if there is no disconnection of any kind.

If after checking and all seems well, then it means the remote is defective. To confirm, borrow a remote, test it with the TV. If it works, then it means you need to replace your remote. But if the remote you borrowed does not work, then it means the problem is from the TV and not the remote.

TV: There is a sensor in the TV that communicates with the remote. If this sensor is defective, the remote won't communicate with the TV.

The TV sensor might have loosed contact from inside of the TV or it maybe defective and need to be replaced.

So do the above troubleshooting and let me know if the problem is from the TV or remote. If problem is from the remote, you need to do a replacement. But if otherwise, let me knows as well.

Yours sincerely

You just check your remote control handset for its infrared emission. There is an infrared light emitting diode [LED], in front of your remote control handset from which infrared light rays are send to your TVs infrared sensor, fitted inside it, behind the infrared window on its front panel. Infrared rays are invisible to human eye. We can check if it is there by using a cellphone with camera option.
Put the cellphone in camera mode, and place your remote control's LED side towards its lens, for about a feet away or so, and when you push its each button, you can see an image in the phones' screen. If it is there, and still your TV don't work with remote control, TVs infrared sensor inside is faulty, and needs replacement.
If there is no infrared image from your remote control, you have to buy one new remote control. OK.

Remote not working

You just check whether the remote control has infrared light emission from it or not. It can't be see with our eye, as infrared rays are invisible to us. Put new cells in the remote handset before you proceed. If you have a cellphone with camera option, the things are easy. Put the cellphone on camera mode, and place your remote control just in front of its lens, at about one feet away or so, press each button on your remote handset, The camera will sense the infrared radiation, and you can see its image on its screen. If there is infrared radiation sign, and still your TV doesn't respond to it, your TVs infrared sensor inside it is faulty. It comes just behind the infrared window ath the front panel of your Tv. It is a three terminal component, and can be resoldered out of the board, and can be replaced. Open your TV, locate it and resolder it from the board. go with that as a sample, and buy a new one with same type and number. its number will be printed [laser markling], on its boady, and should insist on it,a s it is a critical part. Replaceing it will solve your problem. Ok
