1. If the LCD TV's display is broken, it can't be repaired or repaired, because it's difficult to repair the display, and the value of repair is not high. Usually this situation needs to contact the after-sales department to replace the new screen.

LCD TV screen broken can repair it?


2. The LCD TV's display is the main part of the LCD TV.
its price usually accounts for 67% of the whole machine's price, Therefore, the cost of screen replacement will be relatively high.
if the TV has been used for a long time,
the cost performance of screen replacement will be relatively low. In this case, it is better to buy a new machine directly.


TV (television, TV, video) refers to the use of electronic technology and equipment to transmit active image and audio signals.
that is, TV receiver is also an important broadcasting and video communication tool, Television was first invented by British engineer John Lodge Baird in 1925.
television uses electricity to transmit moving visual images in real time.
similar to movies.
television uses the visual residual effect of the human eye to display gradually changing still images, The transmitting end of the TV system converts each tiny part of the scene into electrical signals according to the brightness and chroma, and then transmits them in sequence.
the receiving end displays the brightness and chroma of each tiny part according to the corresponding geometric position to reproduce the whole original image.
the progress of science and technology is an important reason for the rapid popularization of TV.
TV signal scanning in various countries The standard is not the same as the broadband channel.
according to the recommendation of the International Radio Advisory Committee (CCIR), the Latin alphabet is used to distinguish them.

the receiving end displays the brightness and chroma of each tiny part according to the corresponding geometric position to reproduce the whole original image.
the scanning mode of TV signals in various countries is not exactly the same as the broadband channel.
according to the International Radio Advisory Committee (CCIR) suggests using Latin alphabet to distinguish.

the sampling, transmission and reproduction of TV signals from point to surface are completed by scanning.
different countries have different TV scanning systems.
in China, 25 frames per second, 625 lines per frame.
each line is scanned from left to right.
each frame is scanned from top to bottom in odd and even lines, In order to reduce flicker sensation.
image information is transmitted during scanning.
when the scanning electron beam returns from the end of the positive path of the previous line to the start point of the next line, and the field reverse path flyback line returns to the top after each field is scanned from top to bottom, it should be hidden.
the line field synchronization signal is transmitted during the line field hidden period.
the scanning of the receiving and transmitting is synchronized, In order to accurately reproduce the original image, can the LCD TV screen be repaired if it is broken? In fact, some of them can be repaired. It's very simple. The master came up with a good idea,
