Check pin 21 and 22 of the LVDS connector for voltage, and also for a short to ground.

Check backlight fuse.

Check that there is 2.7 to 3v on the voltage divider leading from BKL_EN resistors to EN tab of U9701.

See if the feedback pin to U9701 is tied to pin 21 and 22 of the LVDS connector.

If you want real information, provide 820 number of your board so we can provide real component values to check instead of just guessing.
