iPhone 6 Plus no back light Problems

Hello,

I recently bought a no backlight phone to fix but I'm having a hard time with it and I would really be grateful for some help. I will attach some pictures on the board from under the microscope so that might help you guys figure out what's wrong. I have done some testing and I really am not sure what's wrong with the phone. I have seen that someone else has taken off the FL024 and FL2044 filters and has replaced them with solder linking from one end to another pad. I have cleared that and have ordered new filters. I don't know what the next step would be to this repair if that doesn't solve the problem as the iPhone 6 is much easier because you just replace everything. The phone is completely dark and you have to put a light to it to see if very faintly.

These are the screw holes, is this long screw damage?

Do you have ZXW? You may want to check filters, Coil, Diode and Booster IC.

Here is a video that gives a little explanation. But do not jumper the filters...never a good idea to take the circuits protection.

UPDATE: Heres the pic you are asking for on the Backlight traces...

No, I don't have ZXW however, I might have the problem now after having a look further. I now suspect long screw damage. Let me post some pictures so you can judge this because I am just starting out at board level repair and I don't know much but to me, this looks like long screw damage.

ZXW is an invaluable tool to have. You can get free schematics online and I used them too when first starting out, but to have them at hand makes a world of difference. Actually, from the pics, it doesn't look bad, I just did a long screw damage repair a couple days ago and it looked much worse! and only had a few traces damaged I repaired. It just doesn't look very deep, just scratching the top layer. Is it very ... "Spongy" around the screw holes? Like it may have lifted the screw-hole off the board tearing traces? Were the Filters bad when you tested them?

Yes the all the filters related to backlight were tested and has continuity accross however the two filters that I mentioned were just solder bridges and in the pictures you can see were I have removed those. I have ordered the two filters and will fit them soon when they come and has also ordered a jumper wire that I can use for the long screw damage . What traces lead to backlight in the 6 Plus? I think it’s the right screw but I’m not sure. Also would I be able to get a price urge of ZXW of the traces in the screw hole? Thank you very much for the help guys
