Compared with LCD splicing screens, the probability of bright lines and small screen failures in outdoor LED full-color displays is much higher than that of LCD splicing screens. However, in general, these small failures are easier to deal with, so outdoor full-color LED displays There are still many supporters of the screen. So, when the outdoor led full-color display has a bright line, how to deal with it better? Huabang Ying, the manufacturer of outdoor full-color led displays, will give you a reason.

When a bright line problem is found, we must first judge whether the control card is good. In many cases, the bright line is caused by poor contact or the control card. The control card is easy to detect, so the quality of the control card must be tested first. When detecting the bright line of outdoor full-color led display, you should first turn on the power and check whether the indicator light of the control card is on; if not, check whether there is 5V power supply, and whether the full-color outdoor led display can display content, if it can display Content, the display control card has a good function of displaying content.

This step is tested, only to prove that the control card itself is complete, and the control card software is running well and needs to be tested. The next step is to use the control card software to check the control card. If it is found, it means that the function of the control card sending content is good; if it is not found, check whether the communication line is connected. If it is connected, it may be a problem with the card. . If both functions are good, the LED control card is good, otherwise the control card will be replaced.

If there is no problem with the control card, you need to check the line contacts of the outdoor LED full-color display. Then check the wiring of the power supply and the LED unit board in turn. If it is a power supply problem, it will directly cause several boards to be off or abnormal at the same time, because one board controls multiple boards at the same time, so this is easy to see. The LED unit board only needs to detect a single panel.
