LED display flashes Cause:
1. Driver loader is wrong
2. Between the computer and the screen Hu line is too long or network cable failure
3. The sending card is broken
4. bad control card, check the control card on the small light it? If it is not bright on the bad.
5. The connection between the power supply and the control card is short-circuited.
6. The output voltage of the power supply is unstable, and the power supply with the control card should not bring too many boards.
LED display flash corresponds to the solution:
If it is the whole screen to spend the point, the picture of the new move, the driver is usually not loaded, re-check the driver loader, it is not unloading reload
There is a possibility that the sending card is broken, this time you need to replace the send card
If it is irregular flicker, the general is the system frequency problem. Replace the system, or adjust the settings parameters, the basic can be resolved!
If it is a little bit of flashing state, there may be graphics card driver problem, there may be sending card resolution settings.
Another possibility is the power supply problem (power supply shortage, information clutter, electromagnetic interference), the design of PCB to consider the power and signal routing diameter, and PCB production process.
