Once you have all your modules fully installed and it's the first time you're firing up your screen, sometimes you may notice that there is some damage to the modules or dead pixels. Sometimes this is common due to damage during shipment and during the installation process. All you need to do is remove the modules that had the damage and replace them with the extra spares that we've included with your kit. You'll then pack up the modules in need of repair into one of the boxes that the modules have come into and ship that to the altitude repair facility. We will repair those modules for you and return them back to you so you can place them back on your shelf for future repairs.
