LG tv 49LF5500 screen repeatedly flashes on and off, repair.

On this 49 inch LG television model 49lf5500 the screen and/or picture constanly flashes on and off. This is due to a backlight problem. In this tv there are 5 led strips and only 2 lines. One line lights up 2 strips while the other line lights up 3 strips.
Since the strips are configured in a series circuit the voltage for each line is different. I'm going to show you how to check each individual strip and isolate the single bad LED and LED strip.

MAKE SURE THE PART NUMBER ON THE STRIPS MATCH.
