1. The CCFL (cold cathode lamp tube) of the backlight source is prone to aging, air leakage, breakage, and other defects.
2. The driving circuit of the LCD screen is prone to electrical defects due to electrical components such as ICs, capacitors, etc.
3. LCD screens are prone to defects such as bright and dark spots, lines, etc. due to static electricity, foreign objects, etc.
4. The aging of lamp tubes is mainly distinguished based on brightness and color. The brightness of aging will decrease, and the color of white light will be yellowish. The aging of LCD screens is usually difficult to distinguish, and in severe cases, there may be bright and dark spots or line defects.
5. The LCD display screen is aging because there are also semiconductor components inside, and the LCD will also age.
6. The screen and backlight are separated, but it is important not to repair them yourself, as the assembly and disassembly of the screen and backlight are carried out in a dust-free room and an anti-static environment. This is not possible in ordinary environments, and the replacement of the lamp tube requires the backlight to be removed as it may cause damage to the optical materials. If you have any questions, you can consult the manufacturer first.
