L1 is and inductor not a diode??
check the 3 black TCM to the top of the LCM display connector filters and then check the avddn (all the way to right side),avddh circuit..this will give backlight with no image if they are bad

I've checked TCM and ther are good... I have schamatic for iphone 5s. Which filters do you mean?

I've checked all filters but i can't find fl62... L41,42,44 seems good.

I have to check C444; C94; C350; C351. How can i check this? I dont have good motherbard. Jumpers is not a good solution i think
