As LED display screens become more and more common, you can see LED screens playing text, pictures, videos and other information everywhere in the streets and alleys. However, during use, we will find that there will be a bright line on the LED display screen. In order to make its playback more perfect, how to solve the problem of bright lines on the LED display screen?

1. The product quality is not up to standard. When buying, don't be greedy for cheap and buy low-priced and poor-quality products.

3. Improper operation method, due to human operation errors, affects the effect of the display screen.

First, determine whether the power supply is damaged and whether it can be used normally. Because a power supply controls several unit boards at the same time. You can measure whether the output voltage is between 4.9~5.5v. If it is not within this range, it is likely that the power supply is broken.

First turn on the power and see if the control card indicator light is on; if not, check whether there is 5V voltage power supply and whether the LED electronic screen can display content. If it can display content, it means that the control card display content function is good; then use the control card software to find the control card. If it can be found, it means that the control card has a good function of sending content; if it cannot be found, check whether the communication line is connected properly. If it is connected properly, it is very likely that there is a problem with the card. As long as these two functions are good, the control card is good, otherwise the control card must be replaced.

The signals of the LED display are all transmitted from one board to the input of another board. So if there is a problem with one board, it will affect the subsequent boards. So check whether the unit boards are normal one by one.

After finding out the problem yourself, repair it according to the damage. If you can't repair it yourself, you can contact the manufacturer or send it to the manufacturer for repair. For serious damage, you can ask maintenance technicians to repair it on site to ensure that the LED display can be used normally.
