Remote control doesnt respond

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.

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. In some cases, the remote control might need to clean.

If remote control is working properly, the fault is with the infrared sensor circuit inside the TV. Check and replace the infrared sensor.

Check the remote control for its infra-red emission. Check it with fresh batteries. Check by pressing all the buttons on it; and see whether all of it generates infrared signal while pressing.

Sounds like the infra-red sensor inside it is either damaged or it do not get proper voltage to work. Check it. If it get proper voltage/s and still not receive any infra-red signal from the remote control, replace it. The part in discussion will look somewhat like this.



Prior the replace this component, make sure that the remote control you're using works properly, and do emits infrared light rays, during each button presses on it.

Check the remote control for its infra-red emission. Even new pieces might have the fault. You can check its infra-red emission, by a mobile phone having camera option. If you wish to get more details about how to check a remote control, check this link.http://electronicshelponline.blogspot.com/ If the remote control emits infra-red emission, and still TV do not respond to it, the fault will be due to a damaged infrared sensor inside TV. This part can be located just behind the infrared window at the front panel of the TV set. You have to open the TV, to access it and to replace with a new one. The part will look somewhat like these.

you need to check the battery contact with the battery terminal make sure that the terminal is clean.

check open the cover of your remote and check the solder of the battery terminal from the pcb board use a soldering iron resolder it.

using your cellphone camera test the infra red emmision of your remote control aim the camera to the infra red of your remote.you must see at the screen of the camera that the infra red is lit when any button is pressed..if not the infra red is busted.

using your cellphone camera again to test the infra red emmision of your TV. Aim the camera to the infra red of your TV.you must see at the screen of the camera that the infra red is illuminating.if not the infra red sensor of the TV is busted.

Then it is likely that the infra red receiver in the TV set is faulty - or possibly the 5 volt supply to the receiver.

The signals from the infra red receiver usually enter the system control integrated circuit. So if other control functions are working ok this is likely to be good.

It is possible that other equipment can block the remote signal - if another remote controller is stuck on [jammed down a crack in the sofa] or if you use energy saving lamps in the same room - they can produce high levels of infra red noise.

Please take time to rate my assistance - I hope it is useful.
