At present, the LED display industry is becoming more and more explosive. It has also caused many friends to talk about it. The LED display industry quickly reshuffled. If the operation is not proper or if the technology is not handled properly, the problems faced can be imagined. The daily LED screen "black screen" this failure is the most important. How do we go about judging the black screen of an LED display? How can we handle it? After you have read the following five points, it will naturally be clear.
1. Make sure that all hardware, including the control system, is properly powered on. (Note: +5V, not reversed, wrong)
2. Check and re-check whether the serial cable used to connect the controller is loose or missing. (LED display manufacturers recommend: If it turns black during loading, it may be caused by this reason, that is, it is interrupted during the communication process due to loose communication lines, so the screen is black. Do not think that the display screen is not moving. It's impossible to loosen it. Please check it manually. This is very important for you to solve the problem quickly.)
3. Check and confirm whether the LED display panel and HUB distribution board connected to the main control card are tightly connected or not.
4. Please check and confirm whether the 50-core cable between the connected smart letter control card and the HUB distribution board is loose or inserted.
5. If the display interface definition of your display does not match the provided HUB board, a black screen may also appear. Please check your jumpers for looseness, open circuit or short circuit. If you think that the signals such as ABCD have been matched one by one, please check whether the OE signal is connected correctly. (The LED display manufacturer strongly recommends using a HUB distribution board that matches the display interface definition)
If you have mastered the above points, for the usual LED display black screen "failure" will be handy. Believe that your company handles the problems that the customer feedbacks. The more prosperous life is. The above experience is shared with everyone. Hope can help you.
