change PA!!!

EDDIESoft

i think it is a rx prob not tx please any other solution

Hi,

I think TX prob. If u can search network but can't access, I think u need check TX filter, PA and antena switch again. For SW, maybe u need write good PM file for it.

just check what Vinh Hai say..... normally PA is the problem in 7610.

If there is no network founded ( same in both 900/1800 Mhz ) after 4 Sec , it is a clocking problem M8 .

try to changed rf ic. if not solved u'r problem try to rehot ic power
gud luck man...............

u mean clock cristal
where is that on the bord?

please check what i am saying no network found in 4 sec

yes check the clocking (26Mhz) out and the power supply of the crystal it self , ( may be missed components ) , after that comes the (RF IC) HELGO .

Ohhh! Sorry about this!
I think that because u say it can have network for 8 hours!!? and after that network gone! Replace 26MHz. For RX u can check RX signal by Oscilloscope machine.
I 'm using 7610 and last time my phone don't have network and can't search any network. I have change 26MHz and now my phone working good. May be helpful for u!.
