Hi.
I have a 820-00165 with backlight flickering after liquid damage on and around LP85550. I have replaced LP8550 and all surrounding components.
BKL_EN - 2.78 V and up. Not steady.
BKL_PWM - 1.473v steady
PPHV_SOSW_LCDBKLT - 24V - 26V Fluctuates.
PP5V_S0 - 5V Steady
PP3V3_s0 - 3.3V Steady
Tried 2 LP8550's
Zero damage to LCD connector or surrounding area.
Thanks
