Here are some possible solutions if your LED display cannot load images:
Ensure that the LED display’s power and signal cables are properly and securely connected. Reconnect any loose parts and ensure the connection is secure if anything falls off.
Make sure your signal source (computer, DVD player, etc.) is working properly and producing the correct signal. To verify that the signal source is working, connect the signal source to another display device, such as a television or monitor.
Make sure the LED display settings are correct: Check the LED display settings to ensure the brightness, contrast, resolution, and other settings are correct. There are times when the wrong display settings can result in the image not displaying correctly.
In case the LED display consists of multiple LED modules, check whether any of them are damaged or loose. It may be necessary to replace or reconnect these LED modules if this is the case. Are you familiar with LED display modules?
Make sure your LED display’s control card is working: If there is a control card on your LED display, make sure it is working properly. The power and signal connections of the control card can be checked, as well as the settings.
If the above solutions do not resolve the problem, it is recommended that you contact your LED display supplier or manufacturer for further technical support or after-sales service. I would like to introduce you to the top 10 Chinese manufacturers of LED displays.
