The LCD strip screen has a series of advantages such as high definition, high brightness, high contrast and high color saturation, and is widely used in many industries. With the maturation of strip LCD screen technology, strip LCD screens have become increasingly favored by users. However, no matter what kind of electronic product it is, it is impossible to be completely free of faults. Therefore, in the use of strip LCD screens, some customers may encounter the situation of black screens. Then why does the LCD strip screen experience a black screen phenomenon? And the solutions? Next, the LCD strip screen editor will give you a detailed introduction. The specific content is as follows:

I. Reasons for the black screen of the LCD strip screen

The strip-shaped LCD screen may have the following possibilities:

1. We check the power supply.

2. Check the code dialing of the set-top box with the strip LCD screen.

3. Check the software parameter Settings;

If all the above are fine, then the driver board of the strip LCD screen needs to be tested and inspected (this is repairable). If all the above are fine, then the strip LCD screen is damaged.

Ii. Solutions to Black Screen on Strip LCD Screens

Basically, the reasons for the black screen of the LCD strip screen can be confirmed from four aspects: power supply, adapter, board card, and screen:

For the inspection of the power supply: If there is no response when pressing the panel buttons and the indicator light does not light up, first measure the voltage with a multimeter. If there is no voltage or the voltage becomes very low, it is possible that there is a problem with the input stage of the power supply circuit, that is, there is a problem with the power supply part. This kind of problem is very common. Usually, it is due to the fuse burning out or the voltage stabilizing chip malfunctioning. Some machines have a built-in switching power supply. Therefore, when we stop the bar LCD screen from playing, we must ensure that the voltage is stable.

Another situation is that the program being flushed out may cause the computer not to boot up, which is just like our computer not being able to boot up. Sometimes it's due to the software, which requires us to purchase new software.
