The continuous popularity of LCD TVs and the continuous decline in prices have attracted more and more families to purchase LCD TVs. But sometimes, LCD TVs that have been used for a while will appear distorted in color, and they are at a loss. Don't worry, I'm going to analyze the causes of color distortion on LCD TVs today and how to deal with color distortions.
LCD TV image distortion is what and performance:
Image distortion is not the same as the actual image. For example, if the aspect ratio is 2:1, but the image becomes 2:0.8, this is distortion. Once the image exceeds its actual pixel, its resolution will be reduced. Simply put: distortion is the loss of image information in the process of transferring the image and the resulting image quality degradation phenomenon.
Performance: As shown in the figure, distorted images can clearly feel the difference.
LCD TV color distortion causes:
One reason: strong electromagnetic interference around the TV
Cause two: The picture tube is heavily magnetized by a magnetic object
Reason 3: It may be that the degaussing circuit is broken
Cause four: The TV picture tube is damaged
Cause five: Color output circuit and video playback circuit problems LCD TV color distortion how to do:
According to the causes of color distortion in LCD TVs, we can be classified into three categories: external interference, degaussing circuit damage, and component damage. Therefore, in dealing with the problem of color distortion in LCD TVs, we can start with these three aspects.
Solution one: Find the magnetic field to interfere with the goods
When there is a phenomenon of color distortion on the LCD TV, first check whether there are any magnetic objects around the TV. If so, then you need to place these items on the principle television. Then you can use a magnet to draw the distorted color from the center of the TV to the direction of the TV frame. This process requires patience. Wait until the color of the TV screen is restored, then you must put the magnet away from the TV. Farther away.
The second solution: the degaussing of the picture tube and the replacement of the degaussing circuit
If the kinescope is magnetized, the degaussing means demagnetizes the kinescope. Defective television degaussing circuit caused the phenomenon of degaussing the TV, this time we need to replace the TV degaussing circuit, enhance the degaussing function of the TV itself.
Solution three: Replace damaged components
Used for a long time, its internal components will be aging and damaged over time, affecting the TV color, this time please do not repair it yourself, please professional maintenance can be.
