NOKIA 3310 Dead - GSM-Forum

Shahrukh · 07-13-2003, 16:40

Hi all guys,
I have a NOKIA 3310 which has a very complex problem. Actually when i give it the digital power supply( the power supply which i use for checking mobile phones) this don't take the pulse. I have tried also flash it but it has not software problem it has a hardware problem. I have changed the CCONT. But the problem is same. What do i do?
plz help me.

MrHazeem · 07-13-2003, 20:09

before changing ccont ....Do u test it if working or not ...? ,and also the new one do u test it ...?,

there is a lot of test points to know if the ccont is working or not ...!....,

now does the phone consume power when u press power buttom ...?

if yes ....continue with testing ccont values ...or may be flash problem ...

if no ...also check vbat line and continue with ccont values ...., also may be pcb faulty ...

good luck ...

MrHazeem can u send me where is this test points??

Hi dear,
I want to ask you that What are the CCONT values? and How can i check the CCONT test points??????
and also How may the PCB faulty?
Plz tell me.
Thanks.
bye.

MrHazeem · 07-14-2003, 22:38

ok ....

to be sure that CCONT is working u must check the folowing 6 steps:
note that u must press pwr key when start testing ...

1. check supply voltage 4 ccont at c227 and C228 must be 3.8v if there is no supply voltage the check L513and L202
2. using oscillscope check sleep clock 32.768 khz at both sides of C220 (see service manual) if not ok then B200 or ccont
3. check voltage at 209/211 must be 2.7
4. check voltage at R402 must be 3.8v and must drops to 0v when u press pwr key
5. check VXO at C243 must be 2.8v
6. check VCORE at both sides if L200 must be 1.7v

now... if these values is ok then ccont is working fine ....,

go to next step ...
check 26 mhz crystal and also hagar and then flash IC ...

u need frequency counter to check if 26 mhz crystal and hagar is working or not ...

g o o d l u c k...

hope this will help u ...

Thanks a lot MrHazeem!

Hi Mr. Hazeem
Thanks for your suggestion.
I will check these values and tell you.
thanks very much again.

Shahrukh · 07-21-2003, 11:52

Hi Mr.Hazeem,
I have checked the CCONT values.
1st step is ok.
But the 2nd step, i can't check it because i have no oscilloscope. For this purpose what do i do? Have you any suggestion?
3rd step What is the 209/211?
Are these Capacitors or Resistances?
4th step R402, there is no 3.8 volts.
5th step there is no 2.8 volts at C243.
6th step there is no 1.7 volts at L200.
and also what are the VXO, VCORE?
and again lot lot lot of thanks Mr Hazeem.
Bye,....

MrHazeem · 07-21-2003, 12:14

First I mean C209/C211 ....sorry ..

secound if u do not have oscilloscope then u can check if there is a signal on C220 using frequency counter it should be 32.768 khz of course ...! ( If u need to be profesinal in mobile repairing then u need this oscillscope )

thired u must check at R402 if this value go to 0v when u press pwr key ...!

fourth VXO is C234 ...but in service manual call it VCO ...!

Fifth When u have not 1.9V on L200 ...This means u have defective CCONT ... try reball/change if necceary ...

good Luck

from where to download the exact diagram with values of capacitor and resistance
so that i can locate the component
help!

Hi Mr. Hazeem,
Thanks for your reply and thanks for your suggestion.
I want to ask you that you know about the prices of Oscilloscope?
If you know so plz tell me.
You wrote that the
1st step check voltages at C227 and C228 must be 3.8 volts, there is realy 3.8 volts it's mean 1st step is clear.
2nd step i can't check the 2nd step because i have no oscilloscope and frequency counter.
3rd step I have check the voltages at C209/211 but there is no voltages.
4th step R402 there is no 3.8 volts and not indication drop voltages when i pressed the power switch..
5th step C243, there is also not volts.
and also 6th step is not show the voltages.
Now plz tell me what do i do?
thanks Mr. Hazeem lot of thanks.
byeee.

MrHazeem · 07-22-2003, 12:14

Reball change ccont

Shahrukh · 07-23-2003, 10:43

Hi Mr. Hazeem,
Thank you very much for your suggestion. But i have done this. I mean i have to do this many times but the CCONT is not working. I buy always new CCONT. But it's not working the problem remain same. Is the new CCONT fault or other. And can you tell me plz about the new CCONT who working fine.

MrHazeem · 07-23-2003, 13:33

Most of the new ccont IC which made in china r faulty ....,

i have a good experince with them .....,

try contact the themobileking .... he has a good quality ic's ...

if u want to buy oscilloscope ....then go ebay ....there is a lot of them and good prices ...( 120$ ...200$)

Good Luck
