What is the black screen phenomenon of strip LCD screen? --TFT LCD screen manufacturer
Strip LCD screen has a series of advantages, such as high definition, high brightness, high contrast, high color saturation and so on. It is widely used in many industries. With the maturity of LCD strip screen technology, LCD strip screen is more and more popular with users. However, no matter what electronic products, it is impossible to be 100% fault-free, so in the use of LCD bars, some customers may encounter the situation of black screen. So, what is the black screen phenomenon of the strip LCD screen? What should we do when the black screen phenomenon appears? Here's the explanation.
1. Reasons for Black Screen of LCD Bar Screen
LCD bars may be made up of the following possibilities:
First, we check the power supply, second check the LCD bar STB code dialing, and third check the software parameter settings. If all the above are all right, then we need to test and check the driving board of the LCD bar screen (which can be maintained). If all the above are all right, then the LCD screen is damaged.
2. Solutions to Black Screen of LCD Bar Screen
Basically confirm the reasons of LCD screen black screen from four aspects: power supply, adapter, card, screen:
For power supply inspection: Press the panel button without any response, the indicator is not on, first use the multimeter to measure the voltage, if there is no voltage or the voltage becomes very low, then one may be that the input stage of the power supply circuit presents a problem, that is to say, the power supply has a local problem. This kind of fault is very common, usually burning insurance or voltage regulator chip presents fault, some machines are built-in switching power supply, so when we stop playing LCD bars, we should ensure that the voltage is stable.
Another situation is that if the program is washed out, it may cause the computer to shut down, just like our computer does not turn on; sometimes it is the reason for the software, which requires us to buy the software again.
What is the phenomenon of LCD screen black screen? The above is all for you to explain. It is suggested that when the black screen situation occurs, the user should contact the after-sales maintenance personnel of the LCD bar screen manufacturer to check and repair in time, so that the screen can not be damaged by disassembling and repairing itself.
