My WD3200JB does not spin up to speed. A careful look through the magnifier reveals a burnt choke (L12) and a couple of cooked pins on the U1 motor-driver chip as well as the end of C6 cooked. Clearly parts need replacing.
I can do microsurgery on PCBs if needed, but would prefer to simply replace the whole card. I understand I might need to swap over the EEPROM U12 so as to keep the drive characteristics relevant. However, if there has been a problem with U1 could U12 also have been damaged?
I tried asking WD Support if they could supply a replacement PCB, but it would not accept my ‘email’. Will try again soon.
I would be grateful for any useful ideas.
