Dust: Because of the high (l0kV ~ 30kV) CRT monitors within easy attract dust particles in the air, the printed circuit board inside the display will adsorb a lot of dust, affect the cooling of electronic components, will produce high temperature leakage phenomenon and burn element led display software, and dust can absorb moisture, corrosion of electronic circuits inside the monitor. Therefore, should usually use the monitor in a clean environment clean should be a dedicated to the display of the dust cover, should be promptly after each use with a dust cover. Poor power supply or power supply has been aging: Many poor quality screen repair computer power supply led, could easily lead to poor or power capacity circuit computer can not keep up when the system is busy, the display screen will appear, especially the phenomenon of jitter. Also, if the computer power supply has aging led display, it is likely to cause the same problem. Put too close to the speakers: the speaker magnetic field effect generated can interfere with the normal operation of the display, the display screen jitter generation and cross color and other magnetic interference. Caused by a virus: Some computer viruses will disrupt the screen display, for example: character upside down, shake the screen, flip the display graphics. Everywhere online screen jitter script led display quotes, enough to make you move after the head as big as a cow. Graphics Card Problem: closely monitor and graphics card, the computer screen can be considered a failure not because of graphics cards, such as: bad graphics. led display price led display _ _ Wufeng 金锐光 electricity provided by the Science and Technology Co., Ltd.
