View Full Version : For new beginners. Nokia NO signal solutions
nokia has 2 dirctories of signal
1-TX(that mean trasmiter)
2-RX(that mean receiver)
3-when i understand that is rx and tx problem???
3/1The most problems of TX are(when you power on the
phone, signal is well but..before the light is off,
signal shut down
3/2 The most problems of RX are (when you switch on
the phone and you have not signal
I DONT KNOW IF YOU UNDERSTAND THE DIFERENCE OF 2 CAUSES?
ANYWAY THESE ARE IN GENERAL
4- Whitch parts of nokia are RX and TX?
4/1- PA (power amplificator)is only TX(trasmiter)
4/2- DUBLEXER is RX and TX too
PA AND DUBLEXER EXEPT THE SIGNAL THEY CAUSE MOST OF
PROBLEMS WHEN NOKIA SHUT DAWN WHEN MAKE A CALL
4/3 HAGAR -is RX and have a little part of TX but 80%
of received signal is hagar
4/4 COBBA is TX and a little RX
but cobba cause most of contact service in nokia
and when you listen bad in earphone
4/5 32.768 KHZ REAL TIME CLOCK cause too much problems
of signal and when the phone shut dawn inormaly
you must listen the ring of the phone if it is
too slowly 32.768khz must be change
4/6 CCONTI TRASMIT ELECTRICITY ALL NOKIA PARTS
most of problems when the phone not swhitch on
the problem is cconti
4/7 FLASH IC cause most of contact service in nokia
and signal ( when you switch on the phone and you
have not signal but only the name operator example
( like only vodafone but nothink signal) is a flash
problem
OK MAN I WISH U UNDERSTAND ME

3310 no signal :
So as you said above:
PA is not the cause !
can the problem be in Swtch antenna since It was the first Rx responsable ?
antena switch is too responsabil of rx problems .but i dont understand well what are you trying to tell me?
In a 5210, it can find network manually and works fine. When on automatic network selection, it can't find signal. WHat could be the cause?

nice question here man
yes! and on dct 4 a 6310 and 6100 that can not find signal, switched PA, and ant switch also saw... what could be??? upp? uem? the ic underneath the saw???
regards
5210 is a nokia delusion phone .100% of his problems is the flash ic and cpu.in your problem i see that your memory is not working well you must change (or hot flash ic)
and after flash the phone with a good flash file.this is one way (the problem of your memory ) but in signal problem dublexer make a switch of signal must change it!
ok in 6310 and 6310i most of signal problems is HAGAR. if he can not find signal the problem is the receiver RX and a hagar is the most responbil for these in rx not exluse and dublexer but 85% is hagar
when i say hagar i mean (mjolner)

HI:
I´d like to know a reliable way to know if network problems are from PA or antenna switch (without oscilator or any tool).
Thanks and regards

I´d like to know a reliable way to know if network problems are from PA or antenna switch (without oscilator or any tool).
Thanks and regards
As I understand in First thread :
When the signal comes in the moment of power on and drops after minutes or seconds the problem is in 80% of cases PA (power Amplifier ).
and when It is absent at all In this mmement It can be duplexer (switch antenna) or Hagar in 80% of cases .
all that i share here are for they that dont have a aparatures for test nokia like phoenix fps4 fps8 test frame for all nokia ,oschiloscope ,radiotester and others and without oscilator i cant say to you anythink.all that i share here are the experience when i test nokia and i see the really problems how they are .i dont know if you understand me .for me when come a nokia with a signal i test it with all aparatures and get a solution.
you have understand well yes in most causes when the line drops after few sec is the pa.because this is a tx problem and the pa is only tx(trasmiter) but it must be cobba or dublexer because and they have tx too .all that i say here are in general (my experience)i hope that you understand me

Sometimes, you may have to manually select a network, if the service provider operates only single band, not dual band.
Because in dual band, the 900Mhz could be used for Transmit and a complimentary pair is used for Rx in 1800Mhz or the other way round.
Good thread though

For DCT3 phones, use the GO-NO GO software solution with Eeprom Tool, DCT3 Tester etc.
Pls note that the software will not solve your problems, but may point you in the right direction.
And in most cases, solutions to hardware problems can be found in:

good job keep it up*********************** :)
You do not said the function of CPU, RAM ????
Is CPU Function Rx Or Tx ?????
I have try what you said man, but it's still not working.
I have N. 8250 No Signal, I'm checking the Voltage between CCONT and PA it's good, i change the new RF (Hagar IC's). it's still not good, I change all the part's what did you say before, it's still not good. i change the all component from the well phone.
But my experience last is, i changed the RAM Ic's the signal is good.
please answer my question above.
what is function CPU IC's in Signal ?
Why after i change the RAm the signal is good ?
thank's....
Anybody have the same experience with me, please quote!
cpu:(universal central power)you must be too much expert to change it !!!!!!!! but if the signal is bad from cpu, i think that you phone is dead.
about ram i think that your signal was bad from ram and you have sucesfool done these.but you are fortunatly becouse your ram was not protected.and in 90% of 8210 and 8250 ram is protected and you have nothing to do.anyway i speak in generaly for ram and his parts in signal.because i see very well in my laborator when ram is bad in signal becouse the burst analysis tell the frequence too inormaly .
But these thread is for new begeners in nokia signal and i tell the parts of pa dublexer cobba hagar ,i can"t tell him to change cpu in the first 5 nokia experience .
i hope to begin a new thread for experts in nokia signal to discute a new problems in nokia signal,becouse is very important i think!
thanx for the question and good luck from

@keany
cpu=universal central power
sorry if I made mistake but as I know cpu is something like central procesing unit thats the core of sistem and not universal central power for power in nokia is ccont as I know.
Another problem what I have is with 6310 that work ok on some area but in case if signal is low even if phone show 1,2 or 3 bars on signal loose conection on call.already changed PA and switch and don't have profesional rf tester.what can be the problem?
This is something general and sometimes it works. however sometimes doesn't work at all. I prefer to use service manuals and equipment. That's what they are here for.
Don't go and change everything on the phone, find the fault first
yes its sure that if you havent rf tester you must try to change everythink.you have change pa and switch and no resultat .you must try to change hagar now its the only easy solution now
first good dream for the greece they are wonderfool in football.yes this is true.what are you saying but not all have to tester phones with a good aparatures and there is nothing to do only to try to change something and i think that is nothink bad to change ic ,if they are sure that will change well .
good luck man

regards
@keany,
What frequency range oscilloscope are you using? And by digital radiotester do u mean a spectrum analyser? What brands are u using and how much have they cost? I need to see if investing in this equipment will really pay back. Here the service charges are so low...may not be possible to recover the cost in a year's time. May take several years. Most technicians are not investing because they are unsure of whether they'll ever recover the cost AND make a profit (which is the sole motive of all businesses).
@trion dont be afraid to spend something for your work.when i have to buy a equipment 2 years ago i have renunced to a bmw 2002 only to invest to my work:D
anyway contact me in privat .

3310 When I Turn on "Insert sim card", and after few seconds the phone restart with Contact Service.I flash phone with full flash and reheat cobba but no effect.What can I do?
you must test it with a good soft and they tell you wich is the problem coba or flash ic any way must be that coba will change not only hot and other way is flash ic hot or change and after you must flash it with a goog soft

youve explained it very well thanks, its helped me alot
how about 8210 when power on , the phone take sometime to get full signal. What is the prob? I tried changing PA, ANTENNA SWITCH, HAGAR, COBBA, CCONT, still the same problem come out! But receiving and transmitting is in 100% good condition.
JUST taking (receiving time) signal very SLOW, about 30 seconds, (as i know, normally when u power on the phone, the phone will get signal around 5-10 seconds).
@gogomit,
U need to test the phone with eeprom tools. Click "test". It'll give u the reason for contact service. THis thread is for signal problems. Do a search for the downloads if required. Good luck!
@abbeydguru, deltagsm and keany,
None of u guys has told me the specifications of ur equipment and the cost. In my country repairs of mobile phones is done at quite a low cost, so we need to prioritize equipment purchases and work out the period for return on investment. I have other businesses too and will decide on how much to invest in this one.
@gogomit
i have the same experience with you, my friends told to me if your phone showing INSERT CARD and a few second CONTACT SERVICE, you just REPLACE COBBA do not just REHOT, but it will good if you change it. itry to my costumer phone, it's about
6 phone and it works for 5 phone.
Regards
@trion i have buy my equipment 2 years a go 25.000 euro and now we have 3 laboratores if you want to know this
Thanks, I change cobba and reflash phone now the phone work but no signal on 3310.The signal is absent at all .I test with nokia eprom tools but the test is OK. Can this be duplexer (switch antenna) or Hagar?
are you sure that your cobba is ok?
I changed cobba again and solved my poblem.Thanks to all.
I have a 3310 that nevr find the network. I try all software solution but no result.
I tried with DCT repair partner by neb 3.2, with test Tx900 it seems that there is a good signal, but with test Tx1800 there is no signal.
what can be the problem and which IC I should change first? (if it's hardware probleme???)
br
will you specfic well your problem becouse its too short your saying about signal of the phone
br keany
try to change the Antenna switch and see the result!!!
@keany,
That's quite a lot here in my country. With our normal service charges between US dollars 3 to 15 (including some spares) it'll take ages to recover. Certainly rates of equipment have dropped by now, but still i have to do a return on investment analysis before i invest. Also that amount is currently beyond my means, and is beyond that of several technicians. As i said elsewhere, I am not limited to earning from the GSM field. As and when i feel its right I shall invest. Could u please give the details of your equipment; make, model, measurement range?
Thanks
I have 7200 droped phone. It's seem only insert sim card.
Any body have solution and 7200 disassembly manual or video's.
check ur sim reader flip cover( golden metal type) it is coming with special switch connection when u insert ur sim card. clean the pcb contact of the same also. 7200 will not work with normal plastic type sim reader flip.

Very useful for poor countries where GSM is still new, and 3310´s are everyday stuff!
I´ll get my hands on a few 3310´s and post my results..
OK! someone please explain this... I had signal problem in 8210 flashed with good flash -NO luck-thought it was PA e.t.c BUT surely I cant believe always (hardware fault) PA-coz could be several hardware flaws COBBA e.t.c BUT I think theres software fix- then I thought its dead fone may aswell use it as mados calc;) so flashed with MADOS moded full flash-now signal perfect can make & receive calls with NO problems! strange!

NOKIA 7250 nhm j,
I meat with the stanger problem, I got one 7250 with a camera, the phone radio was no radio (radio error) I flashed it and acting good, bu the phone from now can not ring and cannot listen it through speaker but only with Headphone, I tried to update until 7250i but this result contact service, but initial the phone main cover was written 7250 NHL-4 as I know the NHL-4 is for 7210 and NHL -4J is for 7250 also NHL4JX is 7250i, any body who can solve my problem
if u talk in general way, u are almost right in your explanation, but in fact it is much more complex than the way you explain. For example, even if hagar is a ic that don´t give a lot a problems, is one very important ic in bolth cases, Rx & Tx, very important.
anyway with your explanation "newbies" can try t understand the basic working of one phone,
keep on the good work!

If u mean black PA Philips BGY270, u can change it to another. If Ur phone after change has low or no signal, problem will be elsewhere... I changed many BGY270 to PF08109B and worked for me.
yeah! you must change the another pa is ok .but may be that is not a pa problem ,you must see better and explain well your problem to give a really solution

i found in nokia 3310 signal jump after 5 sec ihad try to resold hager but fail . what i do
if you line jump after 5 sec most probility is the trasmiter problem and you must see cobba that is responsabile too much for tx problems after pa .
as i have explain before .
contact me in privat to give the instructions
In nokia 3310 black PA RF3103 can be replaced by PF08109B and vice versa without any problems.
wat of 3310 that trip of whenever signal wants to come in?................ is it rx , tx probs or wat can be responsible ?

When you put the phone next to a fm radio and hear that noise means that you have tx but you can not use the radio as a tester because sometimes the phone has tx but is not good.

And what we can find out when we try to manual search network.

but you dont be afraid when 1 phone when you change hagar cobba pa dublexer ect,

CCONT, COBBA, HAGAR has no legs but balls. If u want to replace them, u have to have new piece, or u can use used one (if u are sure that this part is OK) but u have to reball it. Sometimes it works without reballing, but that is bad repair. And repeated heating of pcb is not good for phone too...(and for falling signal check track from VBATT to PA..)
3310 When I Turn on "Insert sim card", and after few seconds the phone restart with Contact Service.I flash phone with full flash and reheat cobba but no effect.What can I do?
mostly it is a water danaged phone...
reflash v6.33
rebuild IMEI
inital sim locks
set faid
restore full factory defaults
tested 1000%
good luck
I really thank you for a good job done.But I have 5 nokia 2100,6 nokia 3310,and 4 nokia 8210 with network problem.When you power the phone ,the signal will come,stay for some second and disappear.I removed and reflow their PA and antenna swItch.The problem still remain.Which component or ic do I need to change or reflow.One of my problem is that I can't change ccont,hagar or cobba,because of their tiny legs.I find it dfficult to fix them with my hot air.Can you descrbe for me how to fix THEM :)
i guess you have to change your spairparts supplier.
you can change unprotected I.C`s with some skill
protected I.C`s (like in nokia 2100) is another matter.
good luck

Good Day!
I'm a Filipino and basically cellphone repair is my first priority since i am studying righ now on how to repair cellphones. Can give me some websites that could help me a lot in my studies?
@ Masterlong conglatulations for your new yob!
the best school to learn really somethink is here ,in other websites you must get only manuals and files ore software but to repair i dont think.
but if you stay here and see all problems of the members and the replays for the problems i am sure that you must be much strong that now in this field .and with a good experience you must become a good technic
best wishes to you

I have one 6310i with no network even on manual search don't find any network and antena switch is already bypassed.I try with phoenix software(ver A12 cracked) to read rssi value but always give some error,questions is on ADC reading all seems to be ok except power amplifier temperature is -273.00 C and vcxo temperature is -55.00 C,and dont't have another phone to make some comparations.But as I know from dct3 if rx is good at power up or manual search for network phone usually see the available network but can't register.in my case i think have no rx on phone.anybody have firmvare for 6310i with netmonitor activated?
and already changed few version of firmware on that phone so is not soft problem.

Hi Everyone!
I have signal problems with a Nokia 8850. The signal was floating up & down and sometimes disappear for a few minutes, but it would come back. I took this phone to a GSM service shop and he replaced the PA chip with an new orginal PA chip.
Well that did NOT fix the problem, because the phone will still lose the signal. In fact, I think that it is worse now than before. Sometimes the phone will lose its signal for an hour or more.
I also noticed that SOMETIMES (not always), if I search for a network using the MANUAL search this will help. But sometimes I have to search for the network MANUALLY 2-5 times before I will get a signal back. I have tried switch the antennas from my 8890 and this did not help.
I am so frustrated and do not know what to do next. Can anyone help me out? Thank you in advance for your help!
Best Regards,
8890guy
PS- I fogot to mention that sometimes I CANNOT make calls even if the signal bar is showing 1 or 2 signal bars. The phone will say "Calling" and then I hear 3 beeps and it hangs up.
PSS- I'm sure that he replaced the PA chip, because my old PA was black and the new one is silver/chrome. I bought the PA chip myself from a Nokia Service Center in the UK.

Yoda_Brno,
I just wanted to say thank you for your help. You were right...the problem with my 8850 was the Antenna Switch!! Thank you so much for helping me. You were the only user on this thread that even took the time to reply. I am so happy because this was a really frustrating problem for me and now my phone is working wonderfully again! Besides this, you also taught me something.

I'm Sorry For Taking Up Any Ones Time. My Name Is Carl I'm New At This Cell Phone Stuff. Bad To Say, Cause I Own A Cel Phone Store.
I Just Recently Had The Opportunity To Meet A Company Across Sea's That Can Supply Me With Inexpensive Tdma Cdma And Gsm Phones. The Thing Now Is, That I Have Not A Clue On How To Make Those Phones Work On The Networks That I Provide. If There Is Any One That Can Give Me Any Guidance I Will Greatly Appreciate It..
try and be specific on the model of phones,confirm their band.US is on single band of 1900mhz.
when the phone shows signal and signal drops before the light is off is not always a faulty PA. in many cases COBBA can be unsoldered or damaged.
keany, you done a good job !!!!!!!!!!!!!!!!!!!. pls where is ccont1 on nokia 3310 ? is the look same on other series of nokia ? how can tx in a 3310 that develop netv prbs after falling into water bev rectified ?
hi i want to u to pls gimme details on how to convert 3590 to 3510 and also give pic diagram on how to do jump trick in 3310 network off and 5 seconds
thanks in advance

@alex1
sure that is not always pa.... if we speak in this way must be hagar must be dublexer and all the components etc etc
anyway i speak in general and the most probabilities is the trasmitter problem (tx) and the pa is only trasmiter (tx) and the first thing is to see the pa.but the best way is to test the phone.and testing phones day by day give me these experiens (in general)not always, becouse to repair phone is so dificult .....a litle of liquid anyway in the pcb that you can not see must get down all aur experience about signal..
thanks for your repaly

@yommex
cconti you must get it only in dct3 phones.you must check it very easy becouse he write ccont.
in dct4 phones cconti non egzist with the ccont name but he is into a uem together with cobba and chaps
uem = CCONT +COBBA +CHAPS
UPP = CPU + RAM
but atention changin them becouse the procedure after is not the same like dct3 phones is to dificult in dct4 you must write imei after changing uem and its not so easy

@Keany,
I faced the stranger problem, I think you can provide a big support on that case,
1. I flashed the 7250-NHL-4 to repair missing Tones and Radio, the radion and Tones is ok but you cannot make a call.
2. I Flashed again with Higher Version this cause contact service message, then I return to original Flasher Now you can make a call but after other side receives the call cannot lister you and the phone cannot buzzing.
3. Now you call 112 (Emergency call) only and talk together,
4. After Tracing throughly reading ifo the product code and other recoding are Zero. Can this be the cause of damage sound function? and why the radio working propare but you should seach it manually. I just measured all ICs around the Voice function the result is OK

what about when search for network manually, not all operators are found?

try try try,,,,,,
why not you get oscilloscope
and measure the RXIP/QP , so you will know it is problem from RF or logic BB!
and if it is RF, then use scope to measure the VCO side power supply and control signal ! also check AFC line at TCXO ......
many thing to check,, can not only "thinking and quess" or just try "rehot ",.,,,,,,,
it will not help in repair, and it has more chance to kill phones !

simply excellent
First VCO or RF ic(cpu is glued & last to check). UEM for me never foulty for no net!@RACER
in the first replay that may be cpu i think that was your experience to give instructions but when you say that uem not fault in network i do not agree with you becouse in too many phones i have check fault in uem(tested) and now they are 100% repaired specily (8310 6510 6310i 3510)in most causes must reball them .

i totally agree with you .but......this is bisness and most of members here and most of their centers, repairs all type of phones (nokia samsung lg motorola sony ericsson etc etc and it is too much dificult and expensive to follou the acsesories and tools to repair them all.and i am with the meaning of specializated centers and members like only for nokia or only for samsung or only for a kind of phone and its better i think becouse you (member)become so good in one field and the bisness go on too much better.i am so sure that one specializated center for one kind of phone repair too much phones than a mix center .and there are a few killed phones
this is my opinion i dont know who agree with me ?

I have faulty 9210i. In czech republic we have 3 operators. 1st works at 900mhz, 2nd and 3rd works at 900/1800 mhz.. I have no signal on this 9210i with 900mhz, with second and third i have, but it takes very long to register network... In manual searching i can see only 1800mhz operators. So I think that PA is faulty. Am I right? Phone didnt felt down, was not drawned in water. but Is normal long searching /switching to 1800 MHZ?
:) sorry not so great ...normal
yes i see your problem with your 9210i
9210i its so strong phone but when he fault in something its too dificult to repair .
anyway you will see the pa and antena swhitch i think that you have fault there

the question is how do you explain the case
7250 with Sim goes OK calls and all possible function
when you put SIM the phone swiches off in the moment when search network
and shows charging
the question is how do you explain the case
7250 with Sim goes OK calls and all possible function
when you put SIM the phone swiches off in the moment when search network

if it with Sim goes OK ,,,,,,,, and you say put SIM phone switch off ...
i really do not understand what different "Sim and SIM " !
Willy
if it with Sim goes OK ,,,,,,,, and you say put SIM phone switch off ...
i really do not understand what different "Sim and SIM " !
Willywilly i think that his questions is that without sim the phone can call 112(emergency)and whe he put the sim into the phone shut down when trying to search network..in this way of problem you must flash it and your phone must be ok (if the question is like i explained)
regards
well, it be happen too, if not flash rom or flash data no good, then it must be UEM problem in BB side !
others, in RF side, must check 900Mhz at Power outgoing level 5 and 1800 outgoing level 0, becasue when make "112" call, you will not know which network provider got into answer the phone call , might be 1800, might 900 Mhz !
it can be happen this way : when you dial 112, then 1800 network provider cellsite got near the phone , so at 1800Mhz no problem , but when he insert the Sim or SIM , which might be 900Mhz provider , if PA got no good in 900Mhz, then ofcouse over current will make reason to power off the phone !

hi! owen007,it all depends what pro you used for flashing your 3650 after flashing you have to rebuild the IMEI# have you done that?if no then you have to do it hope fully you will get rid of the signal problem
wbr Daanish
you make in your phone *#06# if your imei is ?????????????????? (probabily not )have to rebuild it, in any other case you dont make the step to rebuild imei ..
the second for the network try to reball mjoelner and see the conclusions ..

i dont know what was your problem of 3100 before flash ? and your phone switched on now ? too much explains for your phone

I dont know if this is gonna help anybody, 6310i no net, tried reflow of pa & antenna switch & mjolner nothing achieved....Symptoms where some network when on and after some time no net at all, first thing i did was reflowing the pa then signal dissapeared completely...So tried refloing of the antenna switch and mjolner but same thing no network....
The manual selection was available partially it could detect networks but could not log on..
So tried changing antenna switch AND pa the phone came back to life but i dont know what causing the problem...I am suspecting just the pa..:) anyway thanks for the info guys..good work and very usefull thread :)
i have samsung A800 when prees power button it shows as if going to display but when i release power button it goes off and also another is nokia 2100 i flashed it after it asked for security code and i updated ui settings but no change,i also tried to change imel coz its imel had changed to 00000000000000 and rebuilt it but to hell,can you help?
hi! you dont have to flash the fone if you dont know your securty code any way now you have to use the nokia tool 18 to change imei# update faid and full fectory set it will be ok if no then you have to upload the virgin eeprom and flash the fone again but still after flashing you have to do the same as i said above

and what happen when the phone is on and the signal ok for long time, but I don't know why suddenly the signal goes out (and I stay at the same place). Then you restart the phone and the signal comes again..
Why this happen???

check the realibility of your PA and the CCONT, or inquire about the effectiveness of your GSM operator. I advise u try to reflow your PA

any questions for signal ,you must replay here.
majorly 3310 signal problem could be associated to no tx or rx but this an majorly be solve : no tx remove the p.a and look for replacement or use a jumper to connect the first two point together left to right.u can visit www.centralpark.net.au for more details.try this it brings an end to ur nokia3310 signal problem.
:) :) :) :) :)
first of all, thanks for this topic
but now I have a problem on some different nokia models, like 6210, 6310 and 6100
I turn on phone and everything is ok (talking on the network)
I make a call and everything is ok too, but if I put my hands over the antena, like trying to "trap" the network, the network bars star falling down until it have no network.
On a good phone, this method cause the network bars to come up again.
I can be almost sure this is not a PA or antena switch problem. CCont and Cobba have been reflowed.... Hagar is the next one to be reflowed (this is in the case of the 6210)
On the 6310 I changed PA, ant switch, refloed mjoelner and nothing too
Have anyone repaired this crazy problem ??? because the phone looks ok, but it is not OK!!!
Thanks all
i have got a problem with one 6310i it works fine full netwerk with 1800mhz but if i put 900 mhz card no signal at all what could be problem
if you can help me thanksss....
