1. Common causes of redness on the side of the LCD TV
1.Signal transmission issues
The signal transmission of LCD TV is realized through HDMI, VGA and other cables.

If there is a problem with the backlight, it will cause the screen to be unevenly bright, and it will appear red. At this point, we can try to replace the backlight tube or adjust the brightness of the backlight to solve this problem.
3.Problems with image processing circuits
The image processing circuit of an LCD TV is an important part responsible for converting signals into images. If the image processing circuit fails, it can lead to a decrease in image quality or even redness. At this time, we need to ask a professional maintenance personnel to check whether there is a problem with the image processing circuit.

At this point, we need to ask a professional repairer to check whether the screen is faulty. If it is indeed a screen issue, you will need to replace the screen to fix the problem.
IILCD TV principle
LCD TVs are designed to control the brightness of pixels by controlling liquid crystal molecules, thus presenting different images. When liquid crystal molecules are subjected to an electric current, they change the direction of their arrangement, which in turn changes the brightness of the pixels. In this process, if there is a problem with some of the pixels, it will cause the color to be incorrect and red.
In short, the redness on the side of the LCD TV is not necessarily a screen problem, but it may also be a problem with signal transmission, backlight, image processing circuits, etc.
