Hi! You need to change PA only! Before replacing PA, don't forget to take away dome folie.

Hi NNarta, I try to change PA, but I got same problem.Can someone help me with another idea? I think that even I remove PA, phone must logon network. Thank's Divji

Hi, divji! No, you can't register at network if you have bad PA. 90% - bad PA, 5% - bad soldering of power supply chip, try to rehot it, 4%- replace chip under battery contacts. 1% - any other problem.

First of all look for good soldering of PA.
