LCD splicing screen black screen how to do

Splicing large screens as high-end display products on the market, providing perfect solutions for traffic safety, energy, power, and other areas of security monitoring, to meet the monitoring screen display in multiple industries and multiple areas. Application requirements.

From the point of view of long-term development of security monitoring, the security monitoring digitalization, dispatching automation, integration of information resources, and central control management of LCD splicing screens also provide a new development path for security monitoring.

The reason for the black screen is basically:

Power, adapters, boards, and the worst result screen is broken.

The first is to check the power: the performance of the panel button without any response, the indicator is off, first use a multimeter to measure the voltage, if there is no voltage or voltage becomes very low, then one may be the power supply circuit input stage presents a problem, also That is to say, there is a problem with the point source. This kind of problem is very common, usually burn insurance or the voltage regulator chip is faulty. Some of the machines use the built-in switching power supply. Therefore, when we stop the LCD splicing screen, we must ensure that the voltage is stable! Another situation is that the program may be washed out and may not start. This is like our computer can not open the machine, and sometimes it is the reason for the software, which requires us to purchase the software.

The appearance of screen flashing on the LCD splicing screen is generally the following:

The power adapter is damaged, the power plug is unstable, the voltage is unstable, the vga line interface is not firm, or the cable is broken.

The solution is: re-connect the vga line, carefully refer to the product wiring instructions, according to the above instructions to seriously conduct the connection, the interface should be plugged in, to avoid short circuit or contact failure phenomenon.

Use a multimeter to test the internal connection lines of the LCD splicing screen to find out poorly-connected or short-circuited lines and replace the high-quality circuit connection lines. Use a multimeter to check whether the power supply of the LCD splicing screen is grounded. The screen flicker may be caused by this reason. If there is a problem, ground the power supply.
