Full-color LED electronic screen Huaping can not be normal display for a variety of reasons, the need to solve the problem of LED Huaping need to do the following five elements:
1, LED electronic screen Huaping can not be displayed
Solution: Check the electronic display power supply is normal, whether there is 220V strong power input
2, LED electronic screen display is not normal, Huaping
Solution:
(1) LED control card parameter settings are correct, there is no signal transmission to the electronic display LED control card;
(2) whether the normal communication line communication, see if the LED control card signal input;
(3) LED control card 5V power supply is normal;
3, the electronic display part of the screen display is not normal, such as black, Huaping
Solution: View the abnormal display of the screen power supply is working; signal transmission line failure; screen single module failure.
A. There is a problem with the output
1, to detect the output interface to the signal output IC line is connected or short circuit.
2, to detect the output of the clock latch signal is normal.
3, to detect the last driver IC between the serial output data port is connected with the output interface data port or short circuit.
4, the chassis heat is not good, resulting in increased graphics temperature caused.
Workaround: Eliminate heat dissipation.
Check the fan running is normal, to the fan refueling, clean up the dust inside the chassis to solve the problem after the heat can be ruled out.
5, reinstall the system, graphics card or monitor does not support high resolution caused.
Solution:
(1) restart the computer, press the F8 key, in the advanced boot menu, select the "safe mode" carriage return system, and then enter the display settings under windows, select the 16-color state, click the "Apply" button, click "OK "Button.
(2) to restart the computer, in windows normal mode, enter the device manager, remove the graphics driver, you can restart the computer.
The above is the full color LED display Huaping reasons and solutions introduced.
