Western Digital Cavier SE16 - fried power coupling-not chips

[natoround]

howdy all, saw some prev posts on these drives and pcb issues. I've not yet taken a look on the underside of the pcb.. .but at this stage it looks like the damage is limited to the power coupling which is fried out on a couple of the contacts on the sata power coupling. Wondering if someone can tell me the liklihood this has caused issues down the line. (ie on the chips) if not can I swap out the pcb for another?

thanks alot
