Apple iPhone 5S - Touch does not work despite replacing the screen

Hello,,

Maybe at the beginning a brief description of the situation. Well, I bought a broken iPhone 5S for self-repair, because I had to deal with such small things, so I took a chance. The phone is generally functional, the system boots without any problems, iTunes can see it. In the purchased phone the screen was shattered, 70% black so it was not possible to check the touch, after replacing it with a new, unfortunately cheap replacement theoretically everything works except just the touch. The touch does not work over the entire surface. So far, I have downloaded the new software by DFU with the silent hope that it will help, unfortunately it did nothing. In the attachment I am sending pictures of screen tapes and disc inputs. I am afraid that the CD is the fault because the phone has a different IMEI number. plates, and another on the housing, for this has non-original batteries from iFixit from which I conclude that the entire iPhone is a cluster of several phones. However, I'm not so familiar with it, so I'm counting on some advice and tips from you.
I apologize for the poor quality of the photo, but I am stuck with old Cyber Shot

Greetings, Kuba

edit:
I noticed today that when the phone is "turned off?" every once in a while something in the center of the screen flashes once. I don't understand it completely.

You are rightly looking for the reason after the disc. The iPhone has such mean verifications of everything and the difference imei macs tracksuit etc. can block components or prevent the phone from completely working. However, this is a tedious and quite complicated operation to do all this, but you will not miss it.
Unfortunately, I am not able to show you how to do it step by step.

What are you talking about? What does imei have to do with touch?

First, a substitute display with a proven and functional touch.
Then you can look for damage further.

Pictures of poor quality but I do not like this touch connector.

Despite the poor photos, you can see that the touch socket on the disc is broken, it needs to be replaced.
Also verify the plug on the panel tape.

What I wrote are only facts confirmed by experience. Trust a second phone that may not have a display for another disc or home button.
As for photos actually enlarged as if one contact in the socket was broken.
Dude, please keep the tone of speech professional and innocent.

You are probably right, you got the typical pieces full of allegro.
It will be best if you send it to the seller because from experience I put it in the dark that the "phone" has many more hidden faults.

The seller is a private person, he sold it in the damaged department, so I will be consistent with myself and forgive myself of the dispute with the seller - no one told me to buy it And the phone itself will probably unfold, in the end buzzer, camera and not one small part. is functional so they will probably be useful in the future. Thanks for the answers, a big lesson about telephones with Allegro

I haven't read such nonsense for a long time ...

And as for the phone, if there is only a broken pin from the socket (and the pads on the board are whole), then replacing the socket is the most profitable.


Iphone 70% of phone value - Motherboard
Samsung 70% of the phone's value - Display

I looked again at the pictures and there are both sleeves ripped out, total chamois. Fight with the seller because it's a dark topic.

I did as I said, the telephone is open.
I bought it very cheaply and the parts will not go to waste
