so we are talking about the "Sandforce SF-2281 controller" I guess.

There are some companies out there which can recover it.

But, first IMHO you (anybody who is a pro!) has to check what's the fault. Is is a power supply chip for e.g. the controller, is it a simple fuse,
is it a destroyed voltage regulator, etc... is it the chip itself, and so on...

Normal, to check whether a chip is broken or not you have to -> measure it. (anything else - please don't get me wrong - is guessing)
(ok, not if completly destroyed / burned, etc... )

Bye,
