Nokia 3330 signal drops to zero - GSM-Forum

jeanfleur · 01-17-2004, 15:24

I have a Nokia 3330. When I put phone on, it has signal. After 5 seconds signal is gone.
I have upgraded MCU + LP with latest version, but not good yet.
Who can help me with this.

After manual searching if it can feels the networks , it could be the
PA , cobba , or ant-sw.
By the way did U updates the faid and resets factory settings ??

in most cases this is PA problem ...

@Medz
Yes, I have reset factory settings after flashing MCU + LP
As I read from your answers, I am afraid it is PA.

If it is not emmeting any signal out ( use lighet sticker ) it could be
PA.
But if it gives signal out each 15-20 sec. for a coupple times it may
be cobba , some times just reflow is enoughf.

Good luck Br

It means that phone doesn't have TX and there is severe reasons for that... First, check software faults ( bad flash, eeprom and faid/imei calculation )... After it, try to get tx with wintesla ( testing/rf controls/tx and set power level to 5 ) and try to calibrate tx power level...

If still no tx, check power supply to PA, PA itself, antenna switch, TXIQ signal, TXDET, cobba, hagar...

first make sure your receving area is ok, then go on wintesla service soft or set factory defalut. then go in rolis 1.9 .on the net moniter option. then check it. same position then first put COBBA ic. then check it . not sure then pull HAGAR then clean then fit it.. i think prob.......... 1000% solve for me everytime.

NOTE: if any call attche then YOUR PF IS WORKING 10000% OK.
nobody bit my this conformation. so not need to change pf.. in net come or go down or up it self. this is perfect tip to repair any 33xx or 82xx
but sometimes CCONT also REASON . so u also check it ,
