If the drive doesn't spin up, then the PCB is most likely faulty. Can you see any damage? Was the drive overvolted by a bad power supply?
When swapping PCBs, be aware that most modern HDDs store unique, drive specific "adaptive" information in a serial EEPROM chip. This chip, or its contents, needs to be transferred from patient to donor. In WD drives, this chip is usually located at U12.
Unfortunately your PCB does not have a discrete serial flash memory chip. Instead it stores the adaptive data inside the Marvell MCU (the largest chip). In this case you will need a "PCB adaptation" service.
The following PCB supplier includes such a service for free: http://www.donordrives.com/services
The reason I suggested the PM2 jumper was that sometimes a drive will spin up but remain busy because it cannot access the hidden System Area (SA) on the platters. By installing the jumper, you would be telling the drive not to access the SA, in which case it should come ready almost immediately, if the board is good.
