Hi. I currently have an LG 42LN5700 TV, and when I turn it on, it flashes quickly and then turns off. I opened the tv down to the led backlights, and found that there are five rows of led strips and the three middle ones don't work. So I would like to know exactly which part to change. Thanks

Check the backlight power/driver board. Also check the voltages on the main power board.
