Scratches on the screen of a flat-screen TV can appear for various reasons. The most common are:

Improper use, especially for small TVs that may be installed near objects that could damage the screen. Pets can also cause scratches, so it is better to install equipment in places inaccessible to pets.
Improper care, in particular, the use of rough sponges, abrasive detergents with powder particles or those that are not suitable for glass surfaces due to their aggressiveness.

Regardless of the cause of the damage, you can try to disguise it. But before removing scratches from the TV screen, the device must be disconnected from power.

Manufacturers recognize defective batches of dies

Manufacturers for TV and monitors sometimes admit their mistakes and recall defective batches.

This happened in one store selling video equipment:

It turned out that during the production of the matrix on the conveyor, something went wrong and a defect was discovered in all the produced matrices (as they explained, when the matrix filters were superimposed on each other, the apparatus that did this had to heat the entire surface of the matrix plates, and in one point, the heating was slightly exaggerated, a gloss was formed INSIDE the matrix and, as a result, a stain during operation). Well, as expected, all the products were recalled, and those who managed to buy them got free. repair (replacement).

Another friend with such a stain decided to submit his laptop with a stain on the matrix for an independent examination.

Test result: the cause of the identified defect is a defect in the liquid crystal polarizing filter.
Conclusion: this drawback arose due to the use of low-quality components by the laptop manufacturer that do not provide the necessary MTBF within the period of its normal operation.
the cost of the examination is 6,200 rubles, the period of implementation under the contract is 30 calendar days.

A person with this conclusion went to the warranty service with the intention of going to court in case of refusal of warranty repairs. How it ended is unknown.

Why did they appear?

Let's first take a very general look at how an LCD TV screen works. The first, most noticeable part - the matrix - consists of several thin polymer plates: two polarizers, two electrode films and a layer treated with a conductor, the so-called “liquid crystals”. These films are hermetically sealed to glass (or made from a glass substitute) plates - any delamination will mean breakage. A layer of anti-reflective coating is also sometimes applied.

Behind the matrix there are several diffuser films tightly adjacent to each other, followed by a light source or sources. The matrix is attached to the electronic filling of the TV using cables, often also polymer. All this is packaged in a plastic case that gives the TV its shape.

LCD monitor matrix layers

The main difference between a modern TV screen and a similar liquid crystal computer monitor is that the LVDS controllers, which are responsible for transmitting the electrical signal, are located on different boards. Since within the framework of this article we are not very interested in the electronic content of the display, and specifically the matrices of both TVs and LCD monitors within the same manufacturing technology are approximately the same, we can say that the methods below will tell you what to do both when repairing the TV and when repairing the monitor.

A scratch on your screen is a classic indicator of the hardness of a material: scratches occur on less hard materials when harder ones are embedded in them. “Implementation” here is a rather conditional formulation: usually it is enough to simply pass one material over another. Unfortunately, all the materials from which LCD display matrices are made are very soft, and almost anything can leave a scratch on them. Glossy screens are much more reliable than matte screens, but even with due diligence, it is quite possible to scratch them.

Perhaps the only advice that can definitely be given to prevent scratches is to not skimp on fasteners. The simplest bracket will cost you twenty dollars - and it will save you nerves for forty years of your life in the future. Hang your TV, if possible, so that a small child, with his arm outstretched, cannot reach the screen - not quite under the ceiling, but somewhere from 130 cm above the baseboard level. Ideally, the center of the screen should be approximately opposite the eyes of the viewer - a child or an adult.

A TV on the wall will also be safe from pets. By the way, even a playful kitten can scratch an LCD TV well - not to mention the fact that any animal, running circles around the apartment or trying to climb somewhere, risks knocking over an expensive device.
