Vertical stripes on an LCD TV

Unfortunately, electronic equipment sooner or later fails. The appearance of stripes on a television screen is one of the most common breakdowns. Strips can be horizontal or vertical, of various colors and widths. Such a matrix defect adversely affects image quality. In addition, vertical stripes on an LCD TV expand over time. Ultimately, the solution remains to replace the matrix, the cost of which is slightly less than the price of a TV. Consider how serious the breakdown is the appearance of stripes on the screen and what to do in a similar situation.

Stripes on the screen - what to do?

A well-made TV for a long time serves the owner, bringing him positive emotions. On a television screen, any program, whether it be Formula 1 or the misadventures of another Izaura, looks more vivid than a 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 dead pixels. There are a lot of reasons for the “striping" of the screen. Let's consider them in more detail.

Causes

Before analyzing the reason why color bars appear on the TV screen, be sure to check that the peripheral cable connection is correct.

Important! Image defects on the screen may appear due to a loose cable that transmits the image or due to a clogged video connector.

What to do first and what are the reasons for the bands on the LCD TV:

  • Check device settings. Set auto tuning. If after this the banding has not disappeared, it will be necessary to understand further.
  • Of course, stripes of stripes are different. They can be thin (several pixels) or wide (covering 5 to 100% of the screen area).
  • The appearance of narrow vertical lines of a certain color is one hundred percent related to matrix problems. Sometimes within a few days this image defect is resolved on its own. If this is not the case, you will have to seek help from a service center.
  • Thin horizontal or vertical stripes on the LCD TV that do not light at all indicate with high probability that the decoder of the rows or columns on the matrix is ​​out of order. This breakdown often manifests itself during sudden power surges or after a lightning strike. The problem is quite serious and one cannot do without the help of a specialist. If you neglect the call to the service center, the strip becomes wider, in the end, 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 cable. In the latter case, sometimes (not always!) The warming up of the place where the cable is attached to the matrix helps. But this is only a temporary solution to the problem.

  • Vertical stripes on an LCD TV that cover the surface of the screen sometimes occur due to a malfunction of the T-KON board or when the matrix is ​​faulty. The exact "diagnosis" can only be made by a specialist service center.

Other options

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

Remember that if color bars appear on the TV screen,

  • it is not always necessary to replace the matrix. Often, repairs are quite inexpensive: eliminating the loose fit of the matrix loop;
  • replacement of the T-KON board that has become unusable with a working one.

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

A striped television screen is an unpleasant thing, but you should not panic. In the vast majority of cases, a specialist service center will quickly fix the breakdown.

Important! The only thing that should not be done (unless of course you are a “pro”) is to try to independently deal with the matrix problems and make any manipulations with it. Mechanical impact, soldering can lead to its final failure. And the likelihood that you will be able to eliminate vertical stripes on the LCD TV yourself is negligible.

Helpful maintenance tips:

  • Most modern TVs have a matrix control board at the bottom. For this reason, experts do not recommend wiping the screen with a wet rag and spraying it with special means. Getting on the board, the liquid causes corrosion of parts. It is far from always possible to repair the matrix. It is much more preferable to wipe the TV with a dry or slightly damp cloth.
  • Handle the antenna cable with extreme caution. One of the most common failures is a torn or broken antenna jack.
  • Do not update your TV software unless absolutely necessary. If it is installed incorrectly, it can provoke incorrect operation of the device or its complete blocking.
