How to check the remote or not. Check the console without special means. How does remote control in modern household appliances

Modern stationary appliances, televisions, music centers, home theaters, air conditioners, etc. are managed, in addition to the buttons on the device itself, using the remote control (PD). A faulty console makes the device defective, delivers users a lot of inconvenience, if not to say that it turns life just into a nightmare. In the material of this article, we consider the remote control with the video camera, a camera, built-in camera tablet, smartphone or other mobile device.

Quite a bit theory, in an affordable form.

How does remote control in modern household appliances

The modulated signal of infrared radiation is used to transmit commands. The digital code is sent to the remote control in the form of "Flash" series. Each "flash" contains a short pulse sequence duration and the frequency of which depends on which of the buttons is pressed.

The signal sent by the remote control is taken by the photodetector inserted into the apparatus.

Before proceeding with the troubleshooting of the remote control system, you need to decide where the fault is located in the remote control pool or in the device itself. Since the emitter of the remote control works in infrared, invisible to the human eye of the spectrum of light waves, check its performance without special devices or devices, at first glance, it seems it will be very difficult ...

Simple and reliable check the remote control You can use the photo of video cameras. You just need to send a remote control to the photo lens or camcorder and click on one of the buttons on the remote control. On the display of the camera, you must see the glowing infrared LED of the working console in the visible spectrum of light waves. Watch the photo at the beginning of the article, No. 1 The button on the remote control is not pressed, No. 2 is pressed by one of the buttons, as evidenced by the glowing emitter (infrared LED).

If, after pressing the button on the remote, you do not see any changes on the camera display, then this indicates its malfunction, to eliminate which, first of all, replace the batteries (batteries).

When any problem appears, it is better not to hurry to throw out the product, and try to repair without the help of others. Moreover, it is not always possible to search for a high-quality remote control of a unique model.

Quite often, the repair of the remote control depends on the type of breakage, and more precisely from the severity of the fault. In any case, what a malfunction would be, it can deliver a lot of troubles. But if you know the types of breakdown, then they can be easily removed.

Because of the frequent decisions of the device, quite harsh breakdowns will be able to appear, the repair of which will have certain difficulties. This is due to the fact that communication in soldering in the scheme is often disturbed. If everything is in order with the batteries, then the console ( electronic device for monitoring and managing the operation of devices, processes and signals) Of course you can check with the camera or cell phone. Since it has an infrared emitter that can detect any tip. This procedure should be made under the following scheme:

1. We turn on the cell phone chamber 1.

3. Take the camera quite close and press on some button of the remote control. If a special signal is to go from the remote, then the blue point should appear on the phone screen.

This is how the performance of the console from the TV is checked if the worker's remote control then try to turn off (plug) from the power supply and connect again to the network. After enroll your own TV. Sometimes it works and the reason is not at all in the remote.

It happens that you click on the remote control buttons, and the TV does not obey. This is especially annoying (if not to say that it just infuriates!) When you are already perfectly settled on your own or your favorite chair, and the remote does not work, but to get up like reluctance. But, nevertheless, you will have to rise from the sofa, because it is necessary to find out what could be the reason, the remote control could be faulty, or maybe something suddenly happened to the IR receiver on the TV. Whether it is possible to check whether the remote is very simple and there will be no complicated devices for this. All this we will do with the help of an ordinary cell phone.

Check the remote control with the phone. How to do it?

In general, this method works not only for remote controls from but for other devices. Here, everything depends not on the device for which this remote control applies, and on the principle of operation of the remote control. Immediately I will say that this method only works for the consoles that operate on infrared radiation. There are still most of these, although now, there are radio consoles to TVs and other devices. You can not check them in this way.

What do we need to check? Ordinary any model. Now, probably, there are no phones left, in which there would be no cameras. It is the camera of your mobile phone that we will need to check the console. The same can be done with any digital but, it is not very convenient to keep it, but it is especially problematic if he is quite cumbersome, and you can not help anyone. So, the perfect option to use your phone for this.

What are we doing? You just need to substitute the remote from your TV under the camera (the camera is turned on and the picture from it should be displayed on the display). It is necessary to do this in such a way that in the chamber you have seen an infrared LED, which stands on all infrared consoles in their upper part.

Next, you simply click on any button of your console and at the same time see what the camera of your phone shows. If the console works, then it must send an infrared signal, you will see it on the phone. The infrared LED will flash purple on the screen of your phone. This means that the batteries are "alive" and your remote control. Although if the batteries are a bit of satisfied, the signal brightness drops. But, you still understand that the remote is your working. For complete confidence in its full performance, it will be necessary to simply replace batteries in it in fresh.

If this helps and your TV will start listening to the remote, it is very good. Well, if not, look for the problem already at the TV itself. It is possible that the receiver of the infrared signal is faulty on it, or something else happened. Here the problem is already more complicated than the home check of the remote control.

And here is also a small video on the same topic. Where you will demonstrate all this. We look. You can check your remote after that.

Elegant and easy way to check the performance of the remote control from the TV without an oscilloscope.

The situation is banal - they came to repair the TV, and there is no remote control to the heap. In principle, everything is solved, we open the console and make sure the tester in the presence of a signal at the input of the radiating diode. But it's not a fact that he himself does not die, in general, without an oscilloscope, we begin to experience obvious discomfort, and who will carry it in the right mind on the line. Although its presence, when checking the console, it implies some clearly unnecessary body of the movement, - suspended to the oscilloscope of the photodiode through which all this is checked.

There is a more elegant solution - indicator of the signal availability from the remote control. This small handkerchief is easily built into the Chinese shooter and allowing you to spend the minimum of time with such a repair.

One thing, not all photos of receivers work from reduced nutrition, imported 5 volts normalized. Although there is an outlet when applying a domestic, free disadvantage. Installed in the latest MSN405 issued.

Perfectly works when nutrition 2.5 volts, which is just suitable for a shorter having a couple of batteries at one and a half volts. The range of work in such a nutrition is 20 cm, but it is quite enough to check the console. With a source of 5 volts, you can naturally put any three-legs photo receiver, the range will be like a TV.

But the Scheme itself, built on the widespread chip 555, is taken from the calculation program for the elements for timer 555.

As a load, R2 can be applied at the request of Piezo Piezo with a built-in generator or without, an LED with a current restriction resistance or all together.

Transistors, I suspect anyone with the appropriate structure and gain coefficient. When the power is applied to the device of five volts, the electrolyte installation is required at least 330MKF for this bus, at three volts if the excitation will not be, then you can do without it.

Modern stationary appliances, televisions, music centers, home theaters, air conditioners, etc. are managed, in addition to the buttons on the device itself, using the remote control (PD). A faulty console makes the device defective, delivers users a lot of inconvenience, if not to say that it turns life just into a nightmare.
