Hello,

I've been trying to replace a board from a WD10TMVV (USB Board). I've just received a 2060-701675-001 (U12 is a SOIC-8) but the original board is a 2060-701675-004 (U12 is a BGA). After U12 replacement, the motor doesn't spin. I've tried also the replace the U14, but is doesn't spin either. Are these boards compatible each other ? Is there any other component that I can replace in order to make it work ?

Thanks and my best regards,
Carlos

It's not BGA package, it's MLP8 package.
The PCB foot print is compatible for both of SOIC8 and MLP8. But you need a bit skill to solder MLP8.

Are the boards compatible each other ? I´ve re-soldered the MLP8 but Hard Disk won´t spin.

Thanks,
Carlos

Try putting an isolator (piece of thick paper) between the PCB and preamp contacts, so that only the motor is connected to the PCB.

Some models won't even spin up if the heads are short circuited. If it still doesn't spin up it could be incompatible, or cooked.

Don't feel bad, I don't even know what he's talking about. Probably a google translate blunder going to/from Chinese.

MLP8, SOIC8, and BGA are IC package types. "Biggerpizza's" observation makes perfect sense to anyone who knows anything about electronics. If you don't understand the terms, then just Google them. There is no need to translate anything.

PCB's is compatible almost totally, but in your case problem is that so MPU code uncompatible with ROM code/IC type of patient ROM. Use the same kind of PCB.

Thanks guys for the support. I'm going to find another board with exactly the same P/N.

1675 board has about 5 different revisions, not compatible with each other.
Not spinning up is exactly the symptom of incompatible board

1675 board was widely used by WD on at least 4 different drive families
Over time it used two different CPUs, two different VCM controllers, featured built-in or external flash and had at least two different boot configs on exactly the same hardware. All combinations are incompatible with each other.

Depending on how rare your PCB revision might be the search might take from some to a lot of time.
