the general technical personnel listed five common LED display screen failures for you1. LED display screen cannot be displayedSolution: check whether the power supply of the electronic display is normal.
whether there is a strong power input of 220 v2. LED electronic display screen display is abnormal, flower screenresolvent:(1) Whether the parameter setting of LED control card is correct, and whether the signal is transmitted to the LED control card of electronic display screen;(2) Check whether the communication line communicates normally and whether the LED control card has signal input;(3) Whether the 5V power supply of LED control card is normal;3. The display of some parts of the electronic display screen is abnormal, such as black screen and flower screenSolution: check whether the screen power supply with abnormal display works normally; Signal transmission line fault; A single module of the screen is faulty.
the screen is faultyA. There is something wrong with the output(1) Check whether the circuit from the output interface to the signal output IC is connected or short circuited(2) Detect whether the clock latch signal of the output port is normal(3) Check whether the cascade output data port between the last driver IC is connected to the data port of the output interface or short circuited(4) Poor heat dissipation of the chassis.
causes the temperature of the graphics card to rise.
causes the temperature of the graphics card to riseThe solution is to eliminate the problem of heat dissipation.
the solution is to solve the problem of heat dissipationCheck whether the fan is running normally.
refuel the fan, clean the dust in the chassis, and solve the heat dissipation problem before the fault is eliminated.
check whether the fan is running normally4. Re install the systemThe graphics card or display does not support high resolutionresolvent:(1) Restart the computer.
press the F8 key continuously, in the Advanced Startup menu, select enter "safe mode" to log in to the system, then enter the display setting under windows, select the 16 color status, click the "application" button, and then click the "OK" button.
after that, click the "application" button(2) Restart the computer.
in the normal mode of windows, enter the device manager, delete the graphics card driver, and restart the computerThe above is the introduction of the causes and solutions of LED display screen splash.
.
the causes of LED display screen splash may be as follows:A. the lamp board file is not correct (reset intelligently.
trace point);B. the package of receiving card and sending card is wrong (check whether the package is the latest package, if not, change it to the latest package);C. if the hardware itself (the card itself has problems) or the connection line (DVI line, cable) is abnormal, cross check and eliminate it.
the hardware itself (the card itself has problems) or the connection line (DVI line, cable) is abnormalFor more information, you can visit Novartis's official website.
