LED display Huaping fault how to solve it? Full-color LED display Huaping can not be displayed for a variety of reasons, where the full-color LED display Huaping how to solve a summary.
If the new screen on the power to spend, it may be set to scan the control card is not correct, or cable is not plugged (check from the control card to the first board of the cable), 5V power supply error will also be the problem.
If the use of a period of time after the sudden discovery of this phenomenon, that in addition to control card failure, the biggest possibility is the board into the water to burn the chip or power.
Also try to take a DVI interface, the first display, look at the graphics card DVI output port is normal signal. General smart rain card, then DVI interface resolution is 1024 * 768. Lead to LED display Huaping reasons, but also may be the graphics card, or drive the problem. Try to unplug the cable from the receiving card behind the display Press the debug button on the receiving card to see if the screen scan is normal.
In addition, caused by full-color LED display Huaping other reasons, but also for your reference:
1, LED display Huaping can not be displayed
Solution: Check the electronic display power supply is normal, whether there is 220V strong power input
2, LED electronic 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.
Solution: Eliminate heat dissipation problems.
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, restart the computer can
The above is the full color LED display Huaping reasons and solutions introduced. From simple to complex, from the basic start to conduct investigation, it will certainly be able to solve the problem. It is not please after-sales service support.
