Self-inspection:
The following phenomena are not failures:
 Given the high-precision production technology, the LED panel may have a very few constantly bright or
dark pixels, which turn out to be tiny red, blue, green or dark points on the panel. The phenomenon is
normal.
 The panel may make slight sound when it is adjusting backlight or it is cooling.
 When the image and sound are normal, and you touch the LED panel with fingers, you may feel static
electricity. The temperature of the rear of the panel and product is high. These are normal phenomena.
