LED Display's Malfunction And Solution
1. The whole led display cannot be enlighted. (black screen)
A: Check the power supply of the LED display, Use the test pencil or the multimeter to check if there is power at the electric end of the switch. There maybe something wrong with the switch or circuit.
B: As for the led display in -phase with PC, first check if the PC were turn into dormancy station or the screen protection station. If it were in the dormancy station, then you enter into the control panel, start the power management, choose the never about the syetem wait and close monitor, then the computer won't in the dormancy station and the LED screen will work normally. If the computer didn't enter into dormancy station, then you can open the outline boarder of the computer to make sure that the controlling card and the signal cable is inserted firmly. Check if the singnal cable were break off. After all these can solve the above question.
C: Check if the signal cable were put through. Please follow the conjunctive print and check-up.
2. The whole led module cannot be enlighted.
A: Several of led module in horizontal cannot be enlighted. Check if the singnal line between normal led module and the abnormal led module were put through.
B：Several of led modules in vertical cannot be enlighted. check if the power were supplied normally.
3. The LED document cannot show the whole picture or the location is incorrect.
A：First, check if the parameter of the software about the led display position and the size of the led display were in accordance with the installtion engineer requested. If you don't remember it, you can count the pixels of the led display to confirm the size. Then you compare the size with the vision place . then adjust the setting of the computer, Until the vision is all the same with the led screen.
B: If the vision is not all-sided as the size of the document , then you need to check whether the document size is the same with the led display size.
C: Open the outline border, check if there is conductor at the controlling card.
4. The led display has no signal.
A: Check if the parameter of the software are accord with the engineer requested.
B: Check if the signal cable and the com connector is ok.
5. The led display has no sound.
This beacuse there is a voice controller in the graphic card which has some collision with the computer voice colltroller, so close the computer voice controller. It will be ok.
