Re: LG 55LA6200 Backlight Issue?

Following this forum with the same symtoms but different tv (LG 55LN5700-UH), I am about to check voltages at the power supply/led driver connections (LED +). I get 84.4 at both LED+ either with LED connected or diconnected, at first second of two, the voltage reads 200v at first LED+ and 123v at second LED+, then both voltages go down gradually and stabilize at 84.4. Is this an indication of bad LED backlights? Or bad powersupply/led driver board? Any assistance will help and is appreciated.
