hey all.

i have waterdamage macbook air, everything looks good except no backlight upon closer inspection (near lvds connector) i found the probe point for ppvout_sw_lcdbklt_fb blown.
Does this mean jumper from pin 5 u7701?

It's possible you can run the small wire from near coil to the diode. Best to replace the LED driver regardless to avoid warranty returns.

A recent post shows a way to recover that brodge.
If no way to resoldar in the central point, then search Louis channel on YouTube, about how to solder a tiny wire in the other side.
You can also see in the same post which points form other side need to be connected.
