Like all premium products, Active LED Video Walls demand expert-led after-sales services. Such services ensure that your screen keeps delivering the promised viewing experience throughout its useful life. In short, the right after-sales service ensures that you get the maximum returns on your investment in LED screens. Some sellers might just provide spare parts for replacements on the other end. We strongly recommend against such practices. A trained technician who understands the screen configuration beyond its blueprint can ensure day-one-like picture quality for the entire usable life of the screen - from installation to the day you choose to upgrade or replace the Active LED display screen. Theoretically, an engineer should open the screen and fix the underlying issue. However, without the necessary training on how to navigate the hundreds of components like small integrated circuits and lamps, the engineer would be left to hits & trials. While there is nothing inherently wrong with the approach, a wrong move can render the screen virtually useless and defeat the purpose of not getting it serviced by a technician. Hence, we highly recommend using the assistance of our trained technicians and authentic spare parts to get the highest quality viewing experience of the longest possible time on your Active LED screens.
