Hi,

I have an A1466 820-00165-A that had liquid contact near the lvds connector, and backlight stoped working.

D7701 seams to be ok, and the area near lvds connector also seams to be ok, and I've replaced the U7701 and the backlight was restored, but afetr a few reboots (3 or 4) the backlight stoped working again.

F7700 is OK (7.59V).

It seams that the area of the BL feedback near D7701 is damaged ( a bit burnt).

Can you help?

Check all traces backlight related.
Pay atention to conectivity between U/D7701 (XW7720).

Check all return resistors.
