Color spots on the tv screen

The appearance of color spots on the TV screen always becomes a real surprise for the owner. Regardless of the variety, such a defect indicates the appearance of serious problems in the operation of the equipment. In most cases, you can identify the cause and solve the problem yourself.

This may cause unforeseen financial expenses that will be associated with the urgent purchase of a new TV.

CRT TV

This variety is one of the first among advanced TVs. The image on such units is demonstrated thanks to cathode ray tubes. A special system for deflecting electron beams creates a full-fledged picture, saturated with a color palette.

There may be several reasons for the appearance of colored spots. All of them are associated with various factors and require different solutions to the problem.

Possible factors:

  • the most common reason is the demagnetization of the standard kinescope system;
  • interruptions of cyclic switching on and off the unit;
  • additional household appliances that create a strong electromagnetic field (in case the equipment is near the TV).

ATTENTION!Spots that appear as a result of a fall or a strong blow indicate a failure of the tube itself.

LCD and LED varieties

Accordingly, the appearance of color spots on the monitor is practically excluded. However, even such TVs are not immune to this malfunction. The reasons are very common.

Occurrence:

  • matrix failure;
  • Possible malfunction of the board responsible for image formation.

Such factors are among the most difficult during repair work. The disadvantage is the possible likelihood that the TV will be completely faulty. This will lead to the purchase of a new device.

Plasma Models

Plasma household devices are one of the most expensive varieties among the presented range of televisions. They are distinguished by a wide range of additional functions, rich color palette and realistic image.

As in the above variety, two options can serve as a factor in the appearance of such a defect:

  • malfunction of image blocks;
  • damage to the power circuit.

ATTENTION!At the first sign, it is recommended that you immediately contact a specialized service for diagnostics and repair work.

How to eliminate color spots from the TV receiver screen

There are not many options for the solution. The advantage of picture tube TV receivers is the ability to carry out repairs yourself.

It is capable of generating strong radiation, which negatively affects the image quality of the TV. To solve the problem, it is recommended to move the devices to a safe distance and check the TV.

Screen magnetization is the most common problem for TV receivers with a picture tube. In this case, the defect can be dealt with in several stages. The TV must be turned off by the network button, and then remove the plug from the outlet. Estimated time - at least half an hour. After the deadline, the procedure must be repeated. Such actions will help to resolve the problem.

IMPORTANT!A similar procedure is recommended to be carried out regularly. This will help to avoid the appearance of such defects and extend the life of the TV.

With the repair of liquid crystal, plasma or LED models, the process is somewhat more complicated. It is quite difficult to diagnose and replace failed parts in the absence of appropriate skills. In this case, a visit to a specialist cannot be postponed, since the appearance of colored spots can adversely affect the operation of all elements of the device. For minor signs of malfunction, contact a professional immediately.
