What are the common skills to solve the problem of LCD module failure?

Solve the LCD module failure common skills are as follows: the current LCD screen production line has been developed to the sixth generation, the seventh generation. The production process is quite complex, it is difficult to replace the broken, for notebooks, digital cameras and digital cameras, LCD module is simply the life of these digital products, should be properly maintained and maintained, as far as possible to extend its service life. Based on the purpose of LCD communication, the common composition of the backlight system and the structure and function of each part of the liquid crystal display module technology are introduced. The We also know that now has entered a high-speed developed information age, information display technology in people's social activities and the role of daily life is increasing dramatically. Information processing, acceptance and transmission operations are through the information system terminal equipment and the interface between people --- the display to complete, so the development of display technology more and more people's attention, after years of technological development, the current LCD Display module-based, the following to a lot of attention under the monochrome LED LCD module group common faults: First, the entire LED display is not normal: 1, check the long cable is plugged in, replace the long cable, check the settings are Correct, reload the settings. 2, check the power cord, display and control card power supply is good. Cable is not plugged in. 12 interface module: the first row of J1-12, the second row of plug J2-12 ... followed by the red side of the red line toward the top of the module, the other side to the side with J1-12 letters. 08 interface plug J1-08 on it. 3, select the text, the text color to red. Second, the LED display has a flash point, the more the more: into the outdoor scan, point high-level settings, select the clock frequency and refresh level, appropriate to reduce the clock frequency, improve the refresh rate until the display is normal. Third, A module area shows normal, B module area has a problem. 1, replace the A module and B module location. If A module and B module display is not normal, with the change B module. If both A and B are displayed, replace the A module, or use it with the last one. 2, with the A module and B module between the cable. 3, check the B module power cord connection is not good.
