Hi my friend i will tell you some thinks that you can do. First check the antena conector is inside the fone you must open it(if you hadn't open t28 older please tell me to explain you).
Secod step is if the fone serching for network and then wrights
No accses probably the problem is the P.A (power amplifiar) to replace that you mast have hot air station.
Do that and tell what you see ok

Dear Ibmboxer
I have replaced brand new 4 PA but no luck.
When we replace and check it is same always searching network.
I think that is hot air station temperature problem.
I don’t know how it use.
Could you Please explain me how PA re soldering ?

Thanks & best regards

atyf,

how did this problem started in your phone? did something happen to your phone and this problem followed? because this problem occured when my phone's original Ericssson battery went dead. I replaced with a new battery, but the problem remained. Also, after this happened my phone gets hot when it is on? Does this also happen to yours?
