How to see if your remote control is actually working

For remotes which use an IR connection you can see if they are transmitting using this trick. An IR type of remote will have one or two LED's on the front end. If it doesn't, than it may be an RF type of remote - this tip will not work for those.

Get some electronic device which can view a live image on a screen. A cell phone camera, digital camera, digital video camera, and (I think) even a web-cam will work. If you're using a digital (still) camera, you don't need to take a picture as long as you see a live image on the screen of whatever the camera is pointing at. Take your remote and find the LED on the front end. There may be one or two. (If there's two, one actually isn't an LED, but that's not too important.) Point the front of the remote at the camera (LED's facing the camera), and press buttons. You should see the LED's light up in the live image. While these LED's normally produce light which the human eye can't see, digital image sensors can, and they change this invisible light to light we can see on the screen. (Cool right?) So, if your remote is working then you'll see the LED light up on the display. (To make sure your camera is actually working as I am suggesting here, find a remote which you know does work and try it.)

The LED should light up for every button pressed. If one button doesn't make the LED glow, you may have a bad button - try pressing it firmly. Buttons can wear out. The image of the LED may appear steady or it may pulse or blink on the viewscreen - this is normal.

If the LED doesn't light up, and you know your camera works like this (you've checked a good remote), try new batteries - that solves most problems. Check the battery contacts in the remote - if they're corroded, (white flaky stuff caked on, looks like dried up salt) - you can clean the contacts with a solution of water and baking soda and a Q-Tip. Use a knife to remove any large chunks. Also, some fine sand paper works too. Both the flat contacts and the springs need to be cleaned. Wash any tools (and hands) with soap and water afterwards. Handle corroded batteries as little as possible - or better yet, use gloves.

If you have good batteries and the contacts are clean, and the LED is not lighting up - it's pooched. Try getting a replacement from the manufacturer (call or email/write them), or use a universal remote.

have tried 2 1 4 all remotes still does not work


You need to check that the IR transmitter on the remote work which means battery and reomte ok.

Simple way is to use a digital camera running in movie mode, than point the remote transmit side to the camera and verify when you press any key that you see a glow on the IR led.

Other than that of course codes and frequency must fit...

manual switch ok but remote not fundtion sharo tv


Be assured that fault does not lie with the remote handset itself. In that case repair or replace it.Remote control system has two parts. One is the remote hand set and the other lies within the TV or other device for which remote controller is being used. The hand set transmits commands in shape of singnals of particular frequency and pulses per second depending on the key pressed. The other part of the remote system lying within the TV receives, decodes and responds according to the commands received in shape of signals of particular frequency and pulses of paricular width and sequence. The remote controller uses invisible infra red light as the carrier of the signal. As the light moves in straight path, no obstacles should block straight line of sight path between the remote hand set (the transmitter) and IR sensor window (part of the receiver). Hence remove the blockage from the front side of the TV.Check if the IR sensor is not defective. Check if the associated circuit and components inside the TV are not defective.Check if the TV has any switch for selecting only manual mode and locking the remote mode.Hope, some sytematic exercise will bear the successful result.

IR Receiver


Are you serious?

In case you are serious, IR=infrared.

When you point your TVs remote control toward the TV and press a button, it is the IR receiver on the TV which receives the IR signal which is transmitted from the IR LED (Light Emitting Diode), which is the small bulb like part, on the front end of your remote control.

Any device using a IR remote control, must have an IR receiver to gather the siganl being transmitted. The IR siganl is a coded message of instructions for the device.
