Vertical stripes on an LCD TV

Unfortunately, electronic equipment sooner or later fails. The appearance of bands on the television screen is one of the most common failures. Strips can be horizontal or vertical, different in color and width. Such a defect in the matrix negatively affects the image quality. In addition, the vertical bands on the LCD TV are expanding over time. Ultimately, the solution to the problem remains the replacement of the matrix, the cost of which is not much lower than the price of the TV.Consider how serious a breakdown is the appearance of bands on the screen and what should be done in such a situation.

Stripes on the screen - what to do?

Qualitatively executed TV for a long time serves the owner, bringing him positive emotions. On the television screen, any transmission, whether it's Formula One or the misadventure of another Izaura, looks brighter than the computer monitor. Grief comes with the failure of the matrix or with the appearance of certain image defects.

The most common defects include the appearance of stripes on the screen and broken pixels. The reasons for the "striped" screen is quite a lot. Let us consider them in more detail.

Causes of

Before analyzing the reason why color strips appeared on the TV screen, be sure that the peripheral cables connection is correct.

Important! Defects of the image on the screen may appear due to a loose cable that transmits the image either because of a clogged video connector.

What to do first and what causes the bands on the LCD TV:

• Check the instrument settings. Set the autotuning. If after that striping does not disappear, it is necessary to understand further.
• Of course, the stripes stripes are different. They can be thin( several pixels) or wide( covering from 5 to 100% of the screen area).
• The appearance of narrow vertical lines of a certain color is one hundred percent associated with matrix problems. Sometimes, within a few days, this image defect is eliminated on its own. If this is not the case, you will have to contact the service center for assistance.
• Thin horizontal or vertical bands on the LCD TV that do not burn at all indicate with a high probability of a row or column decoder failure on the matrix. This failure is often manifested during sudden surges in the network or after a lightning strike. The problem is quite serious and you can not do without the help of a specialist. If you neglect the call to the service center, the band becomes wider, eventually occupying the entire screen. Most likely, you will have to change the matrix, the cost of which is quite large.

Important! The decoder can be located either on the matrix itself, or in front of it, on the loop. In the latter case, sometimes( not always!) Helps warming up the place in which the loop is attached to the matrix. But this is only a temporary solution to the problem.

• Vertical bands on the LCD TV that cover the screen surface are sometimes caused due to a malfunction of the T-KON board or a faulty matrix. The exact "diagnosis" can only be delivered by a specialist in the service center.

Other variants of

The appearance of horizontal lines is caused by the same reasons and is eliminated in similar ways.

It should be remembered that if color strips appear on the TV screen, the

• does not always need to replace the matrix. Often, repairs are quite inexpensive: eliminating a loose fit of the matrix loop;
• replacement of the worn-out T-KON board for work.

All this does not require a lot of time and money.

Striped TV screen is a nasty thing, but one should not panic either. In the vast majority of cases, the service center specialist will quickly eliminate the breakdown.

Important! The only thing that should not be done( unless you are, of course, "pro") is to try to solve the problems of the matrix independently and perform some manipulations with it. Mechanical action, soldering can lead to its final failure. And the likelihood that you will be able to eliminate vertical bands on the LCD TV with your own hand is negligible.

Useful maintenance tips:

• Most modern televisions have a matrix control board at the bottom. For this reason, experts do not recommend wiping the screen with a wet rag and sprinkling on it with special tools. Getting on the board, the liquid causes corrosion of the parts. It is not always possible to repair the matrix. It is much more preferable to wipe the TV with a dry or slightly moistened napkin.
• Handle with the antenna cable with extreme caution. One of the most common failures is the torn or broken antenna socket.
• Do not update the software of your TV without any need. If it is not installed correctly, it may cause the device to operate incorrectly or completely block it.

Now you know why there are vertical or horizontal bands on the LCD TV and what are the possible solutions to the problem. We hope that you have managed only an inexpensive repair or preventive maintenance, and not the purchase of new equipment.
