Main Tips for Maintaining Rental LED Display Screens

As the mostly used displaying equipment for various kinds of audio visual events, rental LED display screens played an important role during these events. Actually, to keep the LED screen work normally and stable, engineers from the LED screen rental companies, as well as the users need to maintain them well. The followings are some useful tips for maintaining the rental LED screens.

Main tools needed for maintain the LED screens: multimeter, electric soldering iron, knife, tweezers.

To find out the problems, we must solve these obvious and serious problems first, then the small problems. The short circuit should be the highest priority problem we should consider about when maintain the rental LED display screens.

1. Observe the rental LED screens first.
Check if all the electric wires, signal wires are connected well or damaged. This is the first step we need to check. Sometimes the electric wires are unconnected or damaged, then it may cause the rental LED screens turned off.

2. Contrast the elements of rental LED display screens.
Some elements, like IC, cannot be judged whether it failed or not just by our eyes. We can use a good IC to change the old one, then check if the problem can be solved. If solved, then the IC is the element that make the LED screen turned off. Pay attention, it is better to ask the engineer from your LED screen rental service provider to disassemble and check the elements inside the rental LED screens if you are not familiar about the screen.

3. Use exclusive method to exclude the problems of your rental LED display screens.
One problem may caused by different factors. We need to check these factors and exclude them one by one, until we find the real factor that cause the LED screen work abnormally.

4. Use resistance test method to test the electric resistance of the rental LED screens.
Adjust the multimeter to the resistance shift, detect the ground resistance of a normal PCB’s, then check the ground resistance of another PCB at the same point. Then contrast if their data are same. The different one will be the damaged one on the LED screen. Most LED screen rental company will use this way to find the problem part on the LED screen.

5. Test the voltage of the rental LED display screens.
Adjust the multimeter to the voltage shift, then detect the ground voltage of some point on the LED screen, and contrast if it is normal. The abnormal area will be the problem part.

6. Test the short circuit on the rental LED screens.
Turn off the LED screen, adjust the multimeter to the short circuit shift and check if there is short circuit problem on the rental LED display screens. If there is, fix it immediately (short circuit is the priority). If you are not known well about the electricity knowledge, it is better to ask your LED screen rental company to send you a professional engineer to fix them, or send the problem LED screen back to them.

Actually, there are many other useful ways to check the short circuit problems of rental LED display screens. When checking the problems, we should follow the above steps and check them step by step. It is better to ask the engineer from your LED screen rental service providers to help maintain the LED screens, since they are familiar about their products and can fix the problem quickly with their professional knowledge.
