Support -> Fix Dead Pixel LED Module

To fix the led display, the best solution is using the spare LED modules because it has exactly the same technical features such as brightness, color etc. If one led screen has been running for 2 year or even more, a replaced new led module would seem very different from the others. The calibration would eliminate this problem, but it cost much and not necessary if the led screen generally performs well.
So each led module is very important, even if it's a broken one.
If you have used up the spare led modules, it would be necessary to repair the broken ones. You could post back the led modules to the led display manufacturers. But sometimes it's not convenient to do that, and if you handle some basic tech skill, you could just fix the led modules on your own.
Here we will introduce how to fix the dead led pixel of the led modules:

1. Prepare the necessary tools: Soldering Iron; Solder; Pliers; Tweezer; Screwdriver.


2. Take off the screws on module mask, and disassemble the module mask from the led module.

11. Add the waterproof material. (Usually the waterproof rubber would not be part of the spare parts, because it belongs to dangerous cargo when transport. You could just use the common-seen silicon sealant, as long as it could be waterproof.)
