[China Glass Network] In daily life, the glass curtain wall led display will inevitably have some small faults after using it for a period of time. So, do you know the common fault problems? Come and learn about the common fault analysis and solutions for the glass curtain wall led display.
Phenomenon 1: The whole screen does not display
The possible causes and solutions for this phenomenon are as follows:
1. The AC power distribution cabinet is not turned on - turn on the power distribution cabinet switch;
2. The computer stops working - turn on the computer and make the computer work;
3. The sending card has no signal, the green light does not flash - set the graphics card to enter the copy mode, if it still can't solve the problem, change the sending card;
4. The signal line that sends the card to the screen is disconnected - check the communication line, if it still can't solve the problem, change the network line;
Phenomenon 2: The whole screen is not displayed properly.
The possible causes and solutions for this phenomenon are as follows:
1. The internal program of the receiving card is incorrect - resend the receiving card program;
2. There is a problem with the computer graphics card or video source - replace the graphics card or video source;
3. The sending card DVI cable is loose - reinsert and fix the DVI cable;
Phenomenon 3: The whole screen is not connected
The possible causes and solutions for this phenomenon are as follows:
1. No send screen program - resend the screen program;
2. The program signal is inconsistent with the actual traces - check the signal traces on the site again and reset the screen connection program;
Phenomenon 4: Water ripple on the screen
The possible causes and solutions for this phenomenon are as follows:
1. The graphics card grade is too low to play HD video - replace a better graphics card;
2. The refresh rate of the screen is set too low - re-adjust the parameters to improve the screen refresh rate;
Phenomenon 5: A single box is not bright
The possible causes and solutions for this phenomenon are as follows:
1. The red power indicator is off, the power is off. Check if the power cord is connected. If it does not work, replace the power cord. If there is no effect, replace the power supply.
2. The green signal indicator does not flash normally or does not light - detect whether the receiving card has power, and check whether the signal line is connected. If the signal line is normally connected, replace the receiving card;
Phenomenon 6: no display of single module
The possible causes and solutions for this phenomenon are as follows:
1. The module displays dark red, the module has no power supply - check whether the power terminal of the module is loose. Now reconnect the HUB board and module. If there is still a problem, replace the HUB board. If the problem still exists, replace the module;
2. The module has no display, and the module has problems - directly replace the module;
Phenomenon 7: Single module is missing color and part is not bright
The possible causes and solutions for this phenomenon are as follows:
There is a problem with the internal components of the module - direct replacement of the module;
Phenomenon 8: A single module has died a certain number of lights
The possible causes and solutions for this phenomenon are as follows:
Use for a long time at the same time, or the screen has reached the end of its life - directly replace the module or a single light bar;
