Well-known but usually machine always has fault, today for the LCD splicing screen fault problems are often encountered in daily use we explain user and caused by fault reasons and Countermeasures of simple.

1, due to power failure caused by the failure of the equipment, power supply is not correct, there are several possible.

A, power supply line or power supply voltage is not correct.

B, power is not enough (or a road power supply line is not enough, the pressure is too large, etc.).

C, power supply system of the transmission line short-circuit, open circuit, transient over-voltage, etc..

D, especially cause equipment damage due to power error or transient overvoltage occur from time to time. Therefore, in the system commissioning, the power supply before, be sure to carefully check and must not be taken lightly.

2, the image definition is not high, the details of the loss, serious color signal loss or color saturation occurs through small.

This is because the high frequency of the image signal loss is too large, resulting in the loss of the signal of 3MHz or above. This kind of situation or due to the transmission distance is too far away, while the middle and amplified compensation device; or because of video transmission cable distribution capacitance is too large, or as a result of the transmission link in transmission line wire and a shielding line between the concentrated distribution of equivalent capacitance caused by.

3, the screen on the screen to produce a number of thin stripe interference.

This interference phenomenon is generated, most of which are in the transmission system, the system front or near the center of the central control room has a strong, high frequency of space radiation source.

Solution: when the system is established, the surrounding environment should be understood, try to avoid or away from the radiation source:

Another way is when the radiation source can not be avoided, the front and center of the equipment to strengthen the shield, the transmission line and pipe line using a good grounding.
