is power switch OK?
PDA is switching automatically when you give battery inside, but phone section you must switch by pressing button. maybe this button is faulty. check keyboard...

hi,
Change the flex.
The problem with the 9210 is that the flex comes as keyboard unit and flex as one.(i mean the flex below the flex cover)
I had this fault a couple of times ,phone dead pda working.
good luck.

Hi,

try put the bad 9210i main board to another 9210 or 9210i for testing the function. Then u will find out which part has problem.
Hopr this can help you for faster troble shooting.

I already put Lower PCB to the other 9210.. same problem..

its main lower PCB is faulty..
but I don't know where is the problem.

Willy told me change FLASH ROM.. but I don't have flash ROM for NOKIA 9210.

Best Regards,
Wahab

DrMobile,
have you solved this fault or no?
Now I have this one like your 9210.PDA work perfect but phone no power on.
Thx and regards.

first test flex connector (is easy and quick to see with microscope)

because I don't know how to test 9210 board, If this problem would mine... I would change most possible faulty components... first reflow/rebouling or change ccont. If ccont don't repair phone then I suspect from flash ic... I think the phone flash ic (not the pda) would be the same like any phone from same time of 9210 manufacture (3310,8210,8850)... monday I will compare flash ic's and will tell u a request

I know that I don't help you a lot... but I will try

best regards
