Emergence of remote controllers for TVs has simplified life. However every time when this useful feature stops working, mood significantly spoils. There are several possible causes of breakage of the device.
Just replace batteries
If the remote controller transmits signal every other time, is periodically switched-off and in general behaves extremely unstably, most likely in it batteries were just discharged. It is enough to change of them, and this useful tool will start over again functioning normally. If you changed batteries quite recently, all the same carry out this procedure. Sometimes the rejected batteries which hold charge very not for long come across.
One more reason of unstable work (or full breakage) the remote control — failure of the transmitter on the remote controller or the sensor of infrared signal on the TV. More often the remote controller transmitter, but not the receiving sensor of the TV breaks. To check operability of distant control, it is enough to walk to any shop of the equipment or on a visit to friends who have the same model of the TV. If the remote controller is impractical, it is possible to give it to repair or to buy new.
In nine of ten cases matter in the remote controller
Sometimes problems in operation of the remote controller are explained by change of frequency messages, as a result the remote controller gives signs of life, blinks bulbs, but the TV does not react to it in any way. And the remote controller can operate other equipment (if, of course, it belongs to universal). In such situation can seem that breakage has occurred in the TV, but not the remote device. It is improbable as remote controllers fail much more (in hundreds of times) more often than directly TVs. So the remote controller at emergence of similar symptoms needs to be given to the experienced expert who will be able to diagnose the causes of breakage and to eliminate it. Sometimes the TV can just cease to react to the remote controller, at the same time the lamp indicator can react to pressing of buttons, but no actions happen. In this case it is possible to switch off and turn on the TV if it does not help, then to update the software of the TV to the latests version. On any modern smartphone it is possible to install the application which turns the smart phone into the remote controller from the TV, the audio system and other equipment. Usually it is necessary to tinker some time with settings, but as a result it is possible to receive the remote controller which is always with you and on which at last it is possible to call. In most cases repair of the remote controller is more expensive purchases new universal or specialized.
