Mickael, this is strictly to identify the components you asked about, not to diagnose your board. F9700 is a 3A 32V fuse in a 0603 package and your backlight driver U9701 is a LP8550. BTW this board has a significant amount of corrosion (marked green in the attached image) which would lead me to believe that it is a water damaged board. [image|785006] You will have to clean it properly and check it for any shortcircuit. Remove the LVDS cable and inspect your connector. I suspect some damage to that as well. Check the pins properly for corrosion and short circuit. At minimum you will need the schematic, board view a multimeter to try to determine which part has failed.
