Hello to all..

I replaced PA on N3310, old one was broken.
Now phone don't power on. Where should be the problem ??
Don't start charger.
Then i've tried to remove PA, but problem remains.
I dunno if phone without PA can power on ..
Any idea please?

Check resistance of PA input power

LSDGSM · 05-17-2002, 04:31

get other board and check one to one if there is all the resistor. Is very easy remove a resistor flowing the PA.

Desolder the pa, and check if the phone will power on. You might have soldered a shorted PA.

Hi,
Ohh Pali as all times you go so quickly

You should to go step by step. You have told that your phone is working before replacing PA. So there's 3 points to verify them:
1- Your PA is damaged and it makes your phone out of work.
2- Your PA is good and you have done a mistake when you have soldred it.
3- Your phone is dead with out any relation with the PA.

Firstly tell me why you have decided to replace your PA ? because may be it's not a PA problem.

Secondly : have you verify mecanical problems ( bad contac, bad connector, swhitch on/off )

Does flasher reconize your phone ?

Mail me PALI, with all description or your ICQ to give me more info, than we will pose the result here.

Good luck
