Hello Ericsson Hardware Experts,

After many searches here, I realised that to repair NO ACCESS / NO NETWORK on Ericsson
(I have heard even also SonyEricsson) phones, the RF PA has to be changed. OK
I have done so on 4 Ericsson phones: T20, T28e, T29s, R320, but to my surprise, they
all still show the same "NO ACCESS or NO NETWORK" !!!

The PA I used was brought in from Dubai and they were Tagged T28 PA
Numbers on PA:
RM009-10P
E38666_1
0024
MEXICO
I am sure of my job, I solder them very neatly with Rework Station, this is since the
phones come on.
So now what seems to be the problem?

This is a challenge to us all !!!
Am I using a fake PA, or is it that PA is not the fault?

Every Ericsson Expert, lets face it.

Starting with you.
