Interrogation: Full Color Led Display Screen
How to solve the problem of LED display screen failure? There are many reasons why the full-colorLED display screen can not display normally. Here is a summary of how to solve the full-color LED display screen.
If the new screen is powered on, it may be that the control card is scanned incorrectly, or the wiring is not inserted correctly (check the wiring from the control card to the first board), and the 5V power supply may be wrong.
If this phenomenon is suddenly found after a period of time, the biggest possibility is that the board water burned the chip or power, in addition to the control card failure.
There is also a display that can try to connect to a DVI interface. First, let's see if the DVI output of the graphics card is normal. Generally speaking, the DVI interface resolution of the smart star rain card is 1024*768. The cause of the LED display screen may also be the problem of the graphics card, or the driving problem. Try pulling off the wire of the receiving card behind the screen and pressing the debug button on the receiving card to see if the screen scan is normal.
In addition, other reasons that cause the full color LED display screen to be displayed are also available to you.
1, LED display screen can not be displayed.
Solution: check whether the power supply of the electronic display is normal, and whether there is 220V strong input.
2, LED electronic display is abnormal, flower screen.
Resolvent:
(1) whether the parameters of the LED control card are set correctly and whether there is a signal transmitted to the LED control card of the electronic display screen.
(2) if communication line is normal, check whether LED control card has signal input.
(3) whether the power supply of LED control card 5V is normal;
3 part of the electronic display screen display is not normal, such as black screen, flower screen
Solutions: Check whether the power supply of the display panel is working properly; Signal transmission line fault; Screen single module fault.
A. output problems
1, check whether the output interface to the signal output IC is connected or short circuited.
2, check the output clock latch signal is normal.
3. Check whether the output data port of the last drive IC is connected with the output interface or not.
4, the heat dissipation of the chassis is not good, resulting in the temperature rise of the graphics card.
Solution: eliminate heat dissipation.
Check whether the fan is working properly, refuel the fan, clean up the dust in the chassis, solve the problem of heat dissipation after troubleshooting.
5, reinstall the system, graphics card or monitor does not support the high resolution.
Resolvent:
(1) Restart the computer, continuously press F8 key, in the advanced boot menu, select enter the "safe mode" return landing system, and then enter the display settings under Windows, select 16 color status, click the "application" button, click the "OK" button.
(2) Restart the computer, in Windows normal mode, enter the device manager, delete the graphics card driver, restart the computer can be.
The above is the introduction of the cause and solution of the full color LED display screen. From simple to complex, starting from the basic investigation, we will be able to solve the problem. Not really. Please provide after-sales service support.
