How to repair TV with your own hands

It is impossible to present a modern apartment or house without video and audio. This equipment is operated daily and therefore breaks more often than others. You can repair TVs in several ways: send a technician to a service center, call a qualified master to a house, or repair it yourself.

We diagnose the breakdown of the

TV. Before we start repairing the TV, we first need to verify what the problem is. This will help if you do the repair yourself, and then, when the master comes, you can explain the situation to him.

There are several types of faults that can most often be found when a TV breaks.

1. Technology does not turn off. In independence, the kinescope TV or the modern LCD model broke, this fault is connected with a blown fuse. Only here different models have distinctive details. You should also pay attention to the diode bridge - perhaps it was he who burned out.

2. In both domestic and import models, the potential can often stray, for which function the posistor responds.
3. If the monitor of a plasma TV is broken, then the problem, most often, is in interference or drops, light or dark stripes may appear, the color changes while watching a program or movie.
4. The problem may be in the breakage of the cord or outlet malfunction.

If we take into account all the troubles listed above, it is worth saying that the most complex breakdown is considered to be a screen fault. For example, on your monitor after getting liquid on the matrix or hitting the TV appear bright glare, then it is better to carry it to the teleservice. Here it will be repaired without fail, and if the warranty period also did not come out, then it is free or at a reduced price.

LCD screen - the nuances of repair!

Some malfunctions of TVs can try to fix it yourself. And here it does not matter - it is the LCD model, LCD or LED, it is not necessary to call the master if you are confident in your abilities. That's just caution never hurts, because such TV models are expensive, and without experience in repair or knowledge in this area can only hurt and exacerbate the breakdown.

Before you begin repairing LED or LCD TVs, you must carefully read the instructions, as well as learn how your model works. Any person, even far from this area will understand that the repair of such TVs as LCD or LED will be different from the kinescope models. In the latter case, you are guaranteed not to encounter a faulty posistor. Here the main thing is to determine the problem, why does the backlight not work?

If you are repairing models of LCD, LED, then here the difference will be only what backlight is used. If it is an LCD TV, then the backlight should be made with fluorescent or fluorescent lamps. For LED TVs, backlighting is done using LEDs. At this stage, the differences LCD models usually end.

What is the cause of LCD TV malfunction?

A breakdown can only consist in the fact that there is no power to check it on the LCD TV, you can do the following with your own hands:

• open the back cover of the model;
• wires connected to the matrix, remove;
• work lamp connected to the contacts;
• there are LCD models in which more than one light source is provided. In this case, it is necessary to test all sources. Just remove the matrix and connect your TV to the network - you can see which LED is the problem.

When a broken lamp is detected in an LED or LCD TV, it must be replaced. This stage requires the master to be as thorough as possible, as well as to show special attention. In some cases, the lamp is removed without removing the matrix, you only need to move the protection elements with a rubber gasket and pull out the light bulb with a soldering iron. Similarly, it is necessary to mount a serviceable light bulb. Now you can be congratulated - you made the LCD TV repair yourself! Just pay attention to one important nuance - the new light bulb must fully meet the parameters and dimensions broken!

To repair your TVs yourself, look carefully at the matrix! If there are “unhealthy” lanes, then the breakdown lies in the matrix. Have a new part? Then everything is simple! You change it and turn on the TV, if it works, it means you have accurately identified the breakdown.

If the reason for the breakdown of LCD TVs is the screen, then it is best to purchase new models of LCD or LED equipment. Changing the LCD screen and LED models is not recommended, as it is impractical! This also applies to the LCD matrix.

What could be the problem with a plasma TV malfunction? If you need to repair plasma TVs, then proceed in the same way as described above. Just adapt it to your specific case. This description can be applied to any model of plasma TV, just stock up on a necessary tool in advance.

We repair kineskopnye models

Although today most users prefer to use plasma, but many still watch transmissions on more outdated kinescope models. Let's learn how to fix the breakdowns in such TVs. Below is a step-by-step instruction that will help you to repair the electron beam product yourself.

• If you do not turn on such a device, check, first of all, fuses. In such TVs, the back consists of panels. Therefore, it is necessary to unscrew that part of the panels. Under such panels you will find a board and you need to connect the power terminals to the fuse. They are connected to a conventional lamp, or rather to its base, after which the TV must be connected to the network. In the event that your equipment is in good condition, the lamp will go out after switching on, otherwise, when the fuse is blown, it will either not work at all or will constantly light up.
• A diode bridge may break. Only it should be borne in mind that it is only necessary to regulate and repair it after making dials. In this case, not only a multimeter is used, but also a product passport, in which the main parameters of this model are indicated.
• The most difficult breakdown in a television with a kinescope is a posistor. To make a check with your own hands, you must first disconnect the power circuit, and then turn it on. In this case, you need to monitor the lamp. If the working lamp goes out, then you can say that the posistor is faulty. To make repairs, you need to adjust the resistance of the network and only want to change this part.

But not only the case can be in posistor, in the kinescope models transistors and capacitors burn down. Diagnosis of this damage can be made visually. If the blackened or cracked condensate, then replace it with a serviceable counterpart. Now you know why the TV does not work and how it will be repaired by yourself.
