I have 7360 no network found and i tried to change p.a ic, antenna switch and filters but still no network found... help me plzzz...

Hi this problem could happen when:
1-your antenna is not attached correctly because your phone crashed or dropped
2- Your antenna switch IC has problem (because dropped or dust or COLD SOLDERING)
3-your matching circuit after the antenna(1 inductance 1 capacitor) cutting off
4- your PA (power amplifier) IC has problem
5-your RF circuit totally is gone
take your cell phone to a certified nokia shop to repair it
kind regard

the same thing is happening to mee.....can plzzz sm1 help mee plzz plzz plzzz....

Maybe there is a problem with your service provider network.Try and use the sim in another handset to check if its working.Try and reinstall the firmware on your phone.

Go to seting-phone setting-network, Choice search network manual.if show all operator the damaged are on PA (transmition IC).but if no operator found the damaged could be on antena or RF IC(as a receiver network)

Hi, there is possibility of the network IC gone bad and should be changes or there is bad contact of the Antenna to the board its good to check the contact .coz if there is poor contact of the Antenna network search will be poor

If searcing manually say no operator found,it means any problem with receifer in your phone,for 2-4 scnd (than operator not found)check antenna and its connector.for 5-7 scnd check switch antenna. for 8-10 check RF IC. for 10 scnd up Check UEM(power IC) and CPU.But for safely do a software repair with a good PM.

Is replacing the ic something I could do myself? Is there more than one ic that I would have to replace?

Some say try new antennas but,I think the major cause is the coax.
I also had a signal problem and did try new antennas,did nothing. Then I find out that the coax they are putting in the newer trucks,like my 2007 is nothing but Junk. You have to start from the source and that is the coax.

simple, reset your settings or soft reset but first backup your phone memory when finished get your mmc and resetnit....
