820-00840 with liquid damage. System powers on and works with external display but no backlight or image on built in display.
Damage was concentrated in backlight area of the board, in particular C8476 PPVOUT_S0_LCDBKLT which was completely melted and trace damaged.
On the bottom of the board I've replaced the following damaged components:
C8475, C8763, C8460, C8462, C8465, C8468, R8401, C8412, R3893, R3894
On the top of the board I've replaced:
C8473, C8474, C8478, C8479
Wondering if maybe Q8400 is bad, but it looks OK after cleaning.
