Sorry I don't know about anything internal on these TVs, but the reason your backlight is going is because it was left at maximum all its life. I'm probably the first to tell you that the backlight on a LCD or LED TV should be turned down to around the midpoint upon unpackaging and plugging it in.
It may appear relatively dim at first, but over time you'll grow to appreciate the more accurate picture.
