1.1). Solution:
Check whether the power plug is firmly inserted into the socket.
Confirm that the power switch is turned on.
Check whether the power cord is intact and if it should be replaced if damaged.
If all of the above are normal, the driver board or control board may be damaged, and professionals should be asked to check and replace related parts.
2). The display screen is distorted.
Possible reasons are poor signal line connection and signal source problems.
2.1). Solution:
Check whether the signal line is firmly connected, and reconnect it if it is loose.
Try to replace the signal source to eliminate the signal source problem.
If the problem persists, it may be a fault in the internal signal processing component of the display screen, and professionals should be asked to repair it.
3). The display color is abnormal.
- Possible reasons:
the driver board or control board is faulty.
3.1). Solution:
Check whether the connection between the driver board and the control board is normal and whether there is obvious damage.
If the connection is normal but the color is still abnormal, it may be a circuit failure inside the driver board or control board, and related parts need to be replaced.
4). The display screen has a black screen, flashing screen, etc.
Possible reasons: power supply problem, damage to internal components of the display screen.
4.1). Solution:
Check whether the power supply is working properly. If there is a problem, it should be replaced or repaired.
If the power supply is normal, it may be that the internal components of the display screen (such as lamp beads, driver IC, etc.) are damaged, and professionals need to be asked to inspect or replace them.
When troubleshooting LED display screen failures, be sure to disconnect the power supply first to ensure safety. If you are not familiar with electronic equipment, it is recommended to seek help from professionals. In addition, regular maintenance and care of the display screen can also reduce the occurrence of failures.
3. Upgrade and transformation of LED display screens
