iPhone 4 No reception after screen replacement
- date: July 5, 2011
I would need the help of an expert here.
A friend of mine broke his iPhone 4 screen. He got a new Screen assembly and did the replacement by himself. Everything works fine, except GSM reception so he asked me to have a look.
I completely disassembled the phone twice but couldn't find any obvious reason to that pb.
- WiFi / WLAN / Bluetooth is fine
- all hardware buttons work fine.
- Screen and Touch are ok
- GPS is ok
The only thing not working is GSM reception. Outside I sometimes do get a very weak signal where my own phone is on full strength but most of the time I just get Network unavailable. Looks like an antenna issue, but I really don't know what / where to check :
- the antenna cable coming from the Speaker/Dock connector Assembly is connected to the logic board
- The little gold plated metal strip at the top of the logic board is in touch with the iPhone housi
