Leave a message
1. The CCFL (cold cathode lamp) of the backlight is simply aging, leaking, broken, and so on.
2. The screen drive circuit has poor electrical properties due to the simple electrical components, such as ICs, capacitors, etc.
3. LCD screens simply show bright and dark spots, lines and other defects due to static electricity, foreign objects, etc.
4. The aging of the lamp tube is mainly distinguished by brightness and color. The brightness of aging will decrease, and the color of white light will be yellow. The aging of LCD liquid crystal screen is usually not easy to distinguish, severely there will be bright and dark spots or line defects.
5. The LCD liquid crystal display will be aging, because there are also semiconductor components inside, and the liquid crystal will also be aging.
6. The screen and the backlight are separate, but you must not repair it yourself, because the assembly and disassembly of the screen and the backlight is carried out in a clean room and an antistatic environment, which is not possible in a normal environment, and the lamp is The backlight must also be removed for replacement. The optical material may be damaged if it is not removed. You can find the manufacturer to repair it. It is not very expensive to just replace the lamp, but it will be more expensive if the optical material inside is damaged.
