Hello,

Backlight IC replaced.

L7701 - 8.5V

BKL_EN -2.8V

BKL_PWM -2.8V

FB - 0V

FB line is not broken. Have continuity.

Fuse is okay.

R7712-22 - 0 oHms. OL in diode mode.

Please advice how to proceed. Thank you!

Possibly bad solders at U7701.
Post diode mode to ground on all return resistors; with red probe on ground!
OL will mean bad solders...

OL on diode mode. Replaced U7701 again and still no BK and OL. Will let it R.i.P.
THanks for your help!

You can ONLY have OL there in diode mode (red probe at ground) if U7701 is not soldered...
