My outdoor LED advertising screen suddenly stopped displaying text, and only some lights are constantly on. What could be the problem? The following are possible reasons why my outdoor LED advertising screen suddenly stopped displaying text, and only some lights are constantly on:
Loose LVDS cable: If the backlight of the display is on normally, but there are no text messages and only some lights are constantly on, it may be because the LVDS cable connection is loose. In this case, you need to check the connection of the LVDS cable and ensure it is securely connected.
Internal hardware failure:
Poor contact or disconnection of lamp cables: If the backlight of the display is not on, it may be due to poor contact or disconnection of the lamp cables.
Power board failure: A power board failure can also cause the display to malfunction, manifesting as no text messages and some lights remaining on.
Control circuit problem between the main board and the power board: A faulty control circuit between the main board and the power board will also affect the normal display of the screen.
Recommended measures:
Check the backlight status: First, confirm whether the backlight of the display is on normally. This is a crucial step in diagnosing the problem.
Contact a professional technician: If you cannot determine the cause of the problem or repair it yourself, it is recommended to contact a professional technician for inspection and repair. They possess the expertise and experience to accurately diagnose problems and provide effective solutions.
Regular maintenance and inspection: To ensure the normal operation and extend the lifespan of outdoor LED advertising screens, regular maintenance and inspection are recommended. This includes cleaning the screen, checking the secureness of connections, and testing the operating status of internal hardware.
