The use of transparent LED screens is becoming more and more widespread, and you can often see them once you step out of the house. It has gradually become a new platform for major outdoor media. When the LED display adds color to people's life, after using the LED transparent screen for a period of time, some failures will inevitably occur. It is necessary and urgent for maintenance personnel to master some emergency faults in the handling method. The analysis and treatment methods of the six common faults of the LED transparent screen are shared with you:

1. The led transparent screen does not work, and the green light of the sending card does not blink

1. Cause of failure: DVI or HDMI cable is not connected correctly; the copy or expansion mode in the control panel of the display card is not set; the software chooses to turn off the power of the large screen; the sending card is not inserted in place or there is a problem;

2. Troubleshooting method: check the DVI cable connector; reset the copy mode; choose to turn on the power of the large screen by software; reinsert or replace the sending card;

2. Transparency does not work, and the green light of the sending card flashes

1. Causes of failure: no power supply to the screen; poor network cable connection; no power supply or low power supply voltage of the receiving card; broken sending card; connection or failure of signal transmission intermediate equipment (such as function card, optical fiber transceiver box);

2. Troubleshooting method: Check to confirm that the power supply of the screen is normal; check the reconnected network cable; ensure that the DC output of the power supply is 5-5.2V; replace the sending card; check the connection or replace the function card (fiber optic transceiver box);

3. The cabinet does not display

1. Reasons for the failure: 220v power cord connection is not good; there is a problem with network cable transmission; the receiving card is damaged; the HUB board is inserted in the wrong place;

2. Troubleshooting method: check the power cord; confirm to replace the network cable; replace the receiving card; reinsert the HUB;

4. The brightness of the transparent screen is very low, and the displayed image is blurred.

1. Reason for failure: Error in card sending program; incorrect setting of function card

2. Troubleshooting method: restore the default setting of the sending card and save it; set the minimum brightness value of the display monitor to above 80;

5. Shaking or ghosting of the entire screen

1. The cause of the failure: check the communication line between the computer and the large screen; check the DVI line of the multimedia card and the sending card; the sending card is broken

2. Troubleshooting method: reinsert or replace the communication line; punch the DVI line for reinforcement; replace the sending card.

1. Cause of failure: The blurred screen is due to the failure of the unit circuit board, which may be caused by chip soldering. One column or a small piece does not light up, the chip burns out, the second half does not light up, the lamp beads burn out, and one column is always on or not on. .

2. Solution: If one column is not bright, please repair and solder the corresponding chip. A small number of chips are not bright, and the corresponding chips need to be replaced. Only by fully understanding the common fault types of LED transparent screens can we find faults in time, find out the reasons, and solve problems quickly.
