I can't give you a definite answer, but it seems to me that there'd be no reason for the display data cable to individually control the separate LED strips. I would think it must set the level for the whole backlight, which the driver board controls. Given that the whole strip drops out, the LED driver board seems the more likely culprit of those two. Does anything different or unusual happen if you change the display brightness when this happens?
