QLEDs are significantly larger than one pixel, while OLEDs Replacing an LED backlight can vary greatly in cost depending on the type and size of the TV, as well as the availability and cost of parts. On average, it can range anywhere from $50 to $500 or even more. If a technician is needed to perform the repair, in addition to the cost of parts, labor costs can add up if the repair is more complex. The half life of LED backlights. LEDs slowly dim over time; half life is the time, in hours, of how long the backlight can operate before its brightness is at 50% of what it originally was when first turned on. So if the half-life is rated at 50K hours, then the brightness of your backlight will be half as bright at 50K hours. PaiF.
