Re: LG 55LA6200 Backlight Issue?
Replaced main/led driver board and led back lights. Back light flashes on then stays off
VDC at P201:
3.4 - PWR-ON = PS-ON
3.1 - DRV-ON = BL-ON
3 - PDIM1 = PWM Dimming 1
3 - PDIM2 = PWM Dimming 2
VDC at P801 (Power On):
LED- *: 0 @ power on
LED+ : 200 @ power on then drops to 88 and is stable
LED- : 27 @ power on then drops to 0 and is stable
LED+ : 125.6 @ power on then drops to 88 and is stable
VDC at P801 when powered OFF:
LED- *: Remains Zero...
