take a look at missing component from iPhone 5 logic board, fixing it

Block Image

hello, my bad is that i bought this iPhone 5 thinking it was the front panel problem.

i have no history or whatsoever of this iPhone 5 only that it has a dark screen issue.

every other thing work fine, outside of the backlight issue at hand. looking at the screen in the sun or with a flash light you will see the images inside the screen.

i have carried out a careful diagnoses on the logic board and found some missing components i don't know their names though. but i named them no:1 and no:2

look at the image and examined it carefully

from no:1

it look like something pulled from the board i might be wrong though. the lines from one end look like something pulled out with force and nothing there to sodder to the board but on the other end there is a lining.

from no:2

clearly the little ic or whatever its called that's suppose to be there is messing.

if i bought a good sodding iron and jump/bridge only no:2

will the backlight come up?

here is a direct link to of the image

opening the board really shows that the phone has been worked before and really rough. but among all it works and can call & received calls.

please help me out, just say something and don't work away.

thanks

I really dont like using wire to extend connection. Do you think merging with with the other one will work?

I will attempt to solder them to gathered when i buys the solding iron. and if it burns i will count my losses.

Yes, I beleive these will affect the backlight

No 1:

FL24 = 240 OHM 0.2A-0.8

(0201-1)

No 2:

C17 = 56PF, 5%, 16V

(01005)

All are on the backlight line in some form. I would suggest replacing them over bridging them and if you are inexperienced, I highly recommend checking out @jessabethany.

Ok thanks.

The no:1 has no board lining to replace or even bridge it.

But no 2 has board lining to jump/bridge it.

Will only 2 bring solved the problem at hand?

Or kiss the two together?

That trace actually goes through the board. I sometimes clean mine up enough to even make a SMALL area to be able to solder to and it sometimes works, otherwise you will more than likely need to run a large trace to the other side of the board. Let me know if you need to know where to run that to

I know it's hard to see above, but I've lifted the pad on a dead board of mine just to show you the little dot you can attempt to solder to.

I will attempt to bridge by solder it across.

I hate to see connecting wire running through the board to bridge. So i might attempt to marge them together.

If it burns i will count my losses
