Outdoor LED display what maintenance skills?We are all clear outdoor LED display in use process, from time to time will meet the wind and rain, sharp, and many other conditions, so the hard to avoid some fault occurs, display once not work properly, will greatly affect the efficiency of the customer, this time LED display maintenance becomes critical, because good maintenance technology can be a good solution to this problem.So what are the tips on maintenance?
First, outdoor LED display maintenance are what skills
1. Interface problem: if the display information controlled by the computer cannot be displayed, please check the cable.
2. Power supply problem: if the LED display USES low-voltage and high-current power supply, there will be little difference in the influence of power supply.
3. Driver problem: if each row or column is not displayed, the corresponding driver chip should be damaged, and then it can be replaced.
4, display problems: long-term use of LED display may damage aging, maintenance can be replaced.
Two, according to the customer‘s display screen can be roughly divided into the following three types:
1. Same interface of display panel
Many LED display manufacturers display unit board interface is not very standard, if the customer‘s outdoor screen display unit board interface and the above interface, we can choose the system upgrade, if the text screen video, low gray video, high gray video, this method cost is low, quick effect.
2. Interface of display unit board
If the display of the customer‘s single element board interface is not completely consistent with the standard interface listed above, but the number and type of signals are the same, this LED display can also be used for upgrading. Of course, because the interface is not completely consistent, the cost is slightly higher than the first case.
3, completely different display unit board interface
If the customer‘s original outdoor LED display unit board interface is completely different from the above, then the cost of transformation will be relatively large in this case.Here, except for the LED display module and some IC, other PCB boards and systems should be replaced, so the cost will be higher.
