What the customer wants is the quality, and what they want is the smoothness in the use process, without any worries. After all, LED display is different from mobile phones, TELEVISIONS, refrigerators and other home appliances, which have been standardized for production. For quality assurance, there is a complete set of after-sales service system. LED as a kind of discrete device, which determines that since its birth, some problems are inevitable. For example, the dead light problem, can you ask which enterprises can do a perfect solution? In addition, as a product with strong engineering attributes, LED display involves a lot of products, and the products of various enterprises are different. The lamp bead, control system, power supply, wiring, chip, unit board and related accessories are almost all different, which brings great difficulties to the after-sales service guarantee of products.\

Needless to say, some of the larger LED display enterprises in the current industry are doing quite well in terms of after-sales service, but for many small and medium-sized manufacturers, both the quality of products and after-sales service are unsatisfactory. And the worst is that some companies or brand agent, although in the process of sales will be associated with the client to sign the service agreement, but as the saying goes, "fine" is never sell buy, some thought of "smart" sellers in the process of product sales tend to additional no-trade clause, or simply for future maintenance buck-passing. Products out of the question, a variety of prevaricate is often, and even more, the fundamental is to do everything possible to cheat, just sell the product, and there is no after-sales service, a problem or push or avoid, let the customer maintenance not, complain no door, can only admit bad luck.
