remote control not working brand new sony rm-lj301 remote


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.

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.
