Hello,

i need PCB for western digital 3200KS

Here are the pictures:





Contact per mail : hitripepe@yahoo.com or PM

Here is also image of back side pcb.
There is no sound of spinnig when i plug in power and this AA chip is going to be very hot.

If by "AA chip" you mean the Marvell MCU (big "M"), then that's a bad sign. Hopefully the serial EEPROM chip survived, in which case you will need to transplant it from patient to donor. This chip contains unique drive specific information. If you are not experienced at soldering, then ask your local TV/AV repair shop. The EEPROM is the 8-pin chip at location U12, just above the Samsung RAM.

Good luck.

I marked the chips on picture.

So for start, which type of pcb must i looking for?
Must be the same just number printed on pcb or i need exactly the same hdd for donor?
The soldering is not the problem

Regards Jani

Hi, I have this working PCB for sale, pls contact my hotmail to see if I can help or not. Thanks, Eric

The Marvell MCU needs two voltages, both of which are generated on the PCB. One is Vcore (~ 1.2V), and the other is Vio (~ 2.5V or 3.3V). Vio also powers the EEPROM and SDRAM.

The smaller component appears to be a MOSFET chopper which is probably associated with one of the above supplies. If the Vio rail has been damaged, then the integrity of the EEPROM may be suspect, in which case you would be wasting your money on a replacement board.

You can test for shorts on the Vio rail by measuring the resistance between the lower left and upper right corner pins (4 & of U12. You could also determine if the failed MOSFET is associated with the EEPROM by measuring the resistance between pin 8 of U12 and each of the components around the MOSFET.

Hello,

Vio rail looks ok, so i hope that EEPROM is OK to.
For now i ordered new pcb by Erik.
Then i change EEprom and i hope that hhd come alive.

I reported the results, when i get new pcb.

Regards Janko

i have this in stock. ROM chip often fine there. you should luck

Hello,

this time i have some good news .

I recived pcb from ERIC and then I swapped bios chip and after that HDD works again.
So i get all my lost data back.

Thanks for help.
