During the use of LCD screens, there may be troubles with blurred screens. The phenomenon of blurred screens in industrial LCD screens may have images on the screen, but the images are covered with interference such as dots, flakes, and mosaics.
If we encounter LCD screen blurred screen, how should we check it? Generally, LCD screen artifacts can be solved by checking signal sources, backlight panels, LVDS signals, motherboards, screen parameters, and LCD screens. The specific process is as follows:
- The wiring problem of the industrial LCD screen is whether the wiring connecting the screen and the motherboard is burned or loosened. The interface should be plugged tightly to avoid short circuit or poor contact. In this case, just change the wiring.
- Use a multimeter to check whether the power supply of the LCD screen is grounded. The screen change may also be caused by this reason. If there is a problem, just ground the power supply.
- Whether the main board of the LCD screen is broken, you can change the main board, but the probability of this is relatively small, but it is not ruled out, you can try to change the main board.
- If the fault phenomenon of the industrial LCD screen is blurred from time to time, the image in the middle of the blurred screen is mixed with many small colored dots. Corresponding maintenance idea: The LVDS plug-in cable is not in good contact.
- If the fault phenomenon of the industrial LCD screen is flowered, the stripes and colors of the flower will change after repeated power-on. Check the backlight
- If the fault phenomenon of the industrial LCD screen is flowered, the stripes and colors of the flower will not change after repeated power-on. Corresponding maintenance ideas: It is likely that the screen itself is broken.
- If the user does not have laboratory equipment for inspection and maintenance, he can also explain the situation to the merchant within the quality guarantee period and return it directly.
