nokia 6310 strange signal problem - GSM-Forum

noone0 · 07-15-2004, 15:09

I have 2 strange 5310

*******r says it looses network, but it has full network
Now I noticed, that when I close my hand near the antenna, it starts lossing network bars.
Can someone help me repairing these phones ??

I changed Antena switch on one of them, but it didn't work out.

Thks for all

your problem is that your phone has a low frequencies. just replace pa ....

Hi guys

I think it sounds like it might just be the external antenna connector that is at fault
Also resolder the bga with mjoelner written on it
It often gets dry joints then when giving phone a slight twist the signal drops away bar after bar

I do not believe its a PA problem

regards D.

but it doesn't lost signal when I twist it.. I'm waiting for the PAs

is there any other PA compatible with the hitachi 08125B ?

MAJESTIC PIRATE · 07-18-2004, 12:56

sure
you can use agilent pa or use pf08109B instead of hitachi 08125B !

Try to rehot UPP,and UEM, but gently,if you overheat UPP You gona have no network, and than You need to replace him.

after changing the pa and antenna switch (from 6210), problem stills the same...
it's very strange!!!!

I heated mjoelner on one phone, to try if it could be its problem, but its in the same condition.

noone0 · 08-16-2004, 23:00

all help is welcome!!!!

As it was said try to solder external antenna connector or you can even short circuit it .

It's rare fault but have you just checked with another antenna ?

PS. If you've changed pa & antenna switch from 6210 , I don't think it's the same, plz confirm !

only the antenna switch was from 6210.
PA is new from 6310i
yes, I already tried external antenna connector

Yoda_Brno · 08-18-2004, 09:26

6310 and 6310i pa`s aren`t same. Be carful. (u can also use 3310 PA but u will lost 190mhz :O) ) check RX or TX problem. if phone has signal andu u can call from it RX is ok if not, find problem in PA, duplexer.... If u cant call on to phone its TX problem. than find problem in MJOELNER / HAGAR...

Aloha
