Hi

I need a pcb for my WD 5000AAVS-00ZTB0
PCB sticker :2061-701444-JOO-AB

The power is gone because use of wrong power supply,so the disc wont spin .

Anyone have any idea where to find a replacement pcb ? Ore how to fix the pcb ? Someone that might be able to fix it ?

Have tried e-bay and a lot of other sites on the net , but no luck at all .

Hate to let all the data on my disc go down the drain .

You may be able to fix it.

See http://www.users.on.net/~fzabkar/HDD/TVS_diode_FAQ.html

... and http://www.users.on.net/~fzabkar/HDD/bi ... diodes.jpg

Sometimes the SMOOTH motor controller is damaged by the overvoltage, especially if the resistors are open circuit. In this case, if location U12 is vacant, then you'll need a PCB adaptation service.

Let us know what you find.

Thanks for helping fzabkar !!!

If my measurement is right I have a damaged D4 TVS diode (12 v )

Any idea where to get it replaced ? ore to get a new diode , might try to fix it myself if that is my last chance.
Have done some repair before , but not a pro .

Thanks a lot for all info, I am learning , and are happy for all the help I can get.

The TVS diodes are for protecting the pcb from Voltage outages , and not necessary for the functioning of the pcb.
If you have a stable and good power supply, then you can remove the TVS diodes and power on the Drive.

Hi
Thanks ..
Ok might try that as a final solution

Your question is answered in my FAQ.

Did you measure R64? If it is open circuit, then be prepared for damage to the SMOOTH chip.

Hi , yes fzabekar i noticed that after I had posted my question .
I have not measured the R64, i will do so when home from work . Have not done anything yet , just wanted to read more and get more info , before I do anything that might damage the hdd more then necessary. I will try to find someone that might repair it for me .
Thanks for all info ..appreciate it

Vance

Finally after many e-mails to several workshops (did not get any response ore answer from any of them ) i had to try to fix it myself , I removed the 12v Tvs diode ,and now the disk is spinning again and I can access my data

Thanks Fzabkar for the helpful links and tip , and to all you others for comments .
