Somebody knows why my 3310 is not charging?

[melvinrc]

I have a big problem, my nokia 3310 is not charging anymore a tried every option to let im charge but nothing happend i tried different chargers different charing blocks different bateries, nothing works, when i put my charger in the phone nothing happens :( maybe somebody here has any ideas....

Youre help is veryyyy welcome

You flashed your phone? If yes flash backup file.

If no try next.

On the PCB on the charger line you have a fuse, is posible to be burned. Verify and if is burned you can try to change it. (see 3310 service manual)
If you don't have a fuse you can try to short circuits on the pin's on the fuse on your risk.(If you have a foulty charger you can damage your phone).

Service manual have a troubleshuting section. See cherger problem.

Let me know if you solved the problem.

have you tried changing the charging pin?
:D :D :D

well i found the problem i am missing a resistor on my pcb (R209) i found the problem in the service manual... the component is shown on the picture i attached, the component is problely lost when i soldered new blue leds on the pcb, well i got the problem but i don't know how to solve it i don't think that these components are sold in electronics shop.... thanks 4 your help i now know what the problem is :D:D:D:D:D:D:D:D:D...

If i get the component and my phone is charging agian i will let you guys know!!

Yes R209 is on the charger line and is a 47K ohm rezistor. You must replace it only with the same value. You can take one from an old PCB board (motherboard, old floppy disk, Hdd)

Codification of SMD 47K ohm rezistor is (473) writted on the body of the resistor.

Colour codification is Yellow, Violet, Orange circle marked on the body of a normal resistor. First circle (yellow) must be placed near of one terminal pin

i found one on an old floppy drive with 473 on the SMD :) only i have another problem now the SMD is to large to fit on the PCB maybe you have an idea how to solve that?... and maybe you know where the trace ends from R210 to R209 and then to... because i think that the trace is missing :(...

[virus2]

No i don't think is mesing because the PCB is a multilayer device has at least 4 layers.
It go to R210 and then at N201 at pin Vchar. But you can solder to PCB one pin and other to R210 with a wire of Cu if the R209 is bigger then space to solder on PCB. You can see on the Service Manual more details.

well i searced on the pcb but i only can find one point to connect the smd on and thats the point that runs from the other smd and further there's nothing to attach it on... so probely if it runs somewere in the pcb i am in deep trouble i gues :( to buy a brand new nokia is in some kind of way a waste of my money because i have a phone but it only is not charging... when i charge my battery in a other nokia and then i put it in my phone i have to set time and date all over again and thats also is not very pleasant if you know what i mean, is there a way to keep the time and date in the telephone when i get my battery out?

[virus2]

I think you get a better lock on the pcb you must find the two point connection for the resistor. You can solder one pin to C216 and other to R210.
Time and date you must set every time you get the baterry out and you can do nothing about this because 3310 don't have a mini battery to hold time settings.

[melvinrc]

Well R210 is not working anymore 2

I will say it this way what would you do if R209 and R210 are not fitteble on the pcb and you want your telephone to charge agian you know my problems on my pcb i have the R209 and R210 SMD's so that is not the problem the problem is to fit it working on the pcb

:( I miss charging :-x

[virus2]

R 210 is on the PCB or no? You tell me that only R209 is out of PCB. R209 place is between the one pin of R210 and C216 or C215. (see on the schematic)
The other pin of R210 solder to ground (GND)
The other pin of C216 or C215 is solder to ground.
You can verify with a ohmmeter.
If you have a R209 SMD bigger then the place on pcb, solder one pin on the pcb (R210 side) and other pin with an Cu(coper) wire soldered to C215 or C216.

or izzit the charging IC ????

[melvinrc]

Well, i tried to fix it but now R210 is not on the pcb anymore and now the phone thinks it being charged all the time, in netmonitor (menu 20) is standing on the first line on the righthandside fstchg that means fast charging, but there's no charger connected to the phone and i can fix it anymore and that sucks...., maybe you know a way to make it think that it is not charging anymore, so i can charge my battery in a other 3310, so that my phone is operating normal without that on the display...

[virus2]

Solder R210 back on the PCB and after that R209. Your phone is not hopeless. Is reparable just be carefull and solder R210 and R209 back on pcb and youl will have a new 3310. If you lost R210 get a SMD resistor with 472(4,7Kohm) writed on the body.
