This is how it looked
Caps removed
Caps
Thoroughly fried MOSFETs
MOSFETs are removed
Diodes' legs disconnected for testing
They tested all OK so they're soldered back
Holes cleaned, new solder added to the pads
Here is one step missing - testing and replacement of the small SMD transistors that drive the MOSFETs
New MOSFETs
The MOSFETs came from this dead Chaintech board
