Over drove nokia - "no signal" - GSM-Forum

terri_power · 11-19-2001, 20:35

My friend accidently ran over his nokia with his car and he gave the phone to me and i have fixed all stuff on it so it works. But i dont have a signal. I have new antenna and new housing. Any suggestions of what might be wrong?

Hello It's simple bad contact for the rf part componet, you just need to use the hot air gun to reflow that.

I got problem on 3210, that has signal coming and going out continiously. I reflowed COBBA, changed VCO's, PA's, 13 mHz, 71 mHz, other little filters, still no joy. What else can be done?

terri_power · 11-21-2001, 21:50

Thankz. I going to try that tomorrow on school. I got an 5110 today with same problem.

terri_power · 11-21-2001, 22:00

Damit. Not sure if this is the components i shall change:

<a href="http://www.inside-gsm.com/Nokia/Nokia_3310/Inside_Nokia_3310/Component_side_description_Nok/component_side_description_nok.html" target="_blank">http://www.inside-gsm.com/Nokia/Nokia_3310/Inside_Nokia_3310/Component_side_description_Nok/component_side_description_nok.html</a>

3 and 5 on this picture? It is the "5. Hitachi PF08109BN dual frequency PA" and "3. Diplexer (RXTX switch)"

mobidoc · 11-21-2001, 22:31

hello m8

look try to measure the voltages found in the service manual first to know if the hager bga is ok, if the voltages r ok , then start by changing the component no 2 i think it will work for u , if u got no signal , then change the pa no 5 , if it didnt work , then try to make manual search if u got a signal & then gone , then change the Diplexer (RXTX switch) .

i think this is a brief description .

hope this can help .

kind regards .

terri_power · 11-22-2001, 00:45

Thankz m8. I have the service manual going to print it out then.

ARC · 11-27-2001, 02:54
