Could we see the original bridge PCB? It may be possible to repair it.

At least that's how it would work for a non-SED. However, your drive is a SED, so I don't know what you should expect to see in these same places.
Were your previous sector dumps taken via SATA or via USB?

The +3.3V regulator may actually be +2.5V, and the +1.2V regulator could be closer to 1V.
