Hi, you changed the wifi flex or you replaced the connector on the board ?
Take a look on the lcd connector if no corrosion,dust , search the schema's here in forum by Wites it will help you to figure what to check .
Better take it to someone who is equipped and can check whats wrong.

In my small town services no repair apple. I changed antenna, flex. Lcd connectors is ok. Maybe is coil ?

Do you have tools to test ?
Can you make good photos of the board ?
Do you have the schema's ?

Noroc si multa concentrare la reparat

Yes, i have " opening tools for iphone " < kit.
Yes, but say in what place on motherboard ? Near connector of lcd ? Or where ?
No, i have pics with motherboard and of each component write his name. This is schema ?

Multumesc, sper sa il pot repara.

No ,sorry but better send it to a professional person....
You need tools to open yes ,but you need tools to measure ,you need to understand a schema ,ect.
We all starting some day ,but if your not passionated by this or is not your job ...You need lot of time to document you and to practice and I think is not a good idea to practice on your phone because you will aggravate the situation .
Banuiesc ca ai rupt poate o piesa cand l-ai manipulat sa schimbi flexul trebuie sa folosesti un microscop(o lupa daca nu ai microscop) si sa verifici placa .

Da solutia asta nu ai vazuto vezi ce e marcat cu rosu daca sunt la locul lor resistoarele Before Open a Thread Search Here Hardware Solutions!

I checked resistors, and all is good. How i can do remove that board ? For check L1, L2, L3. That board near lcd connector.

Am verificat resistoarele si sunt bune. Cum as putea sa indepartez tabla de langa conectorul lcd ?
