Which three points can solve the monitor screen color spot, color halo

As we all know, when the application of a good product is too long, it will cause problems. Sometimes the monitor screen will have some color spots or color halos. This chapter explains how to deal with these problems.

1) Slight magnetization

Solution: Please power off the machine for at least half an hour and then turn it on again. This will solve the local color cast caused by slight magnetization.

2) Thermal arching effect

Solution: If the automatic degaussing cannot be improved, and the spot is confirmed to be obvious in the bright picture part, it can be judged that the picture is stuck in the picture tube thermal arching effect caused by the screen with obvious brightness contrast for a long time. If the new purchaser recommends reducing the brightness of the monitor and turning it off after 20 minutes, it is recommended that the customer try to avoid the monitor staying in the contrast screen for a long time to improve the life of the picture tube; if the product is used for a long time After the problem occurs, it is generally difficult to recover. This problem is an inherent defect caused by the CRT imaging principle. It is recommended that customers avoid this by changing the usage habits (do not display a fixed contrast display for a long time).

3) Severe magnetization

Solution: Automatic degaussing can not be solved, and the thermal arching effect can be judged as severe magnetization of the picture tube. It is recommended to find a service engineer to go to the door for treatment. The general treatment methods are: replace the degaussing resistor, manually degauss using the degaussing tool, and add the degaussing piece.
