[GadgetFriendly]

Hello Fellow Gadgeteers!!! So I was sent this board with 2 traces peeled off!!!.
Fl3 and Fl4 I've been searching around and non of the posts show jumpers when trace is off. looking to properly jumper these too to get backlight working again on this iPhone 4s. Thanks in advance and looking forward to hearing from everyone.

You need to download schematic from sticky thread.


Search for those two filters and try to point out to which other parts the supply goes through.

You can even trace the supply with the help of a multimeter and a working 4s motherboard.

Once the point is found where the supply goes you can trace thin insulated wire And jumper its one end to the point and the other point to the visible part of the broken filter.


P.S: I could have made a good pic for the solution, but im not in my office.

P.S2: Have you tried scraping on the peeled off track with sharp needle? If you scrape carefully you can find very tiny copper dots, that would be your supply you are searching for.

i appreciate it when you get in the office if you have a chance i would love your picture!!! after cleaning the board i do see the copper dot. do you think i can fill it with solder to make a new pad?
