Sometimes the television remote refuses to work. The causes may be disparate. They could be dead batteries, but it could also be the fault of the remote control. To test the functionality you need sophisticated tools.
This guide indicates how to test a remote control with easy methods at home. Before you start, do not forget to check the batteries if they are exhausted. Let’s see specifically how to try the capabilities of the TV remote control.
1.) The first method is very simple. It allows you to test the functions of the remote control, without removing it. Generally, a TV remote control emits a beam of ultraviolet or infrared, so you cannot see and see this signal directly with their own eyes. Even if we try to press the buttons in the dark, we cannot logically see anything. The human eye picks up this type of rays.
2.) The trick is then to resume the remote control with a videophone, framing the portion of the LED diode, the one short, from which exits the signal. At this point, with the image on the screen of the remote control handset, you can press any button on the remote control. If it is in good condition, you will see the flashes on the handset, as if they were a normal light. The handset is able to see the infrared and ultraviolet rays. All this only with the help of an ordinary camera.
3.) Another alternative method is to pull the remote control to a standard AM radio. You first need to tune the radio to a station transmitter is captured. In practice, there must be absolute silence, then you can press any button on the remote control. If it works, the radio will feel the typical rhythmic signals, thus indicating that the remote works ..
4.) If you are more experienced or have been available from a simple digital multimeter or tester, you’ll have another opportunity available. Opening the remote control can observe that the generator of infrared rays is attached for the rest, thanks to two small filaments. Well you just have to check with the multimeter if contact is made by shorting. If it does not pass the second test : You must carefully check all the contacts and find the capacitors burned. Once went into a hardware store and found the facts to the pond to settle. Without this firm with a common welder respecting the polarity.
