Inverter has been confirmed bad. I don't have any output from it.

What usualy go bad with them ? Transfo , caps ?

In my experience, FET's and picofuses. As Michael has said, often the
picofuses go for no reason - replace 'em and you're often back in
business.

Is it a kind of switching power supply ?

Yes. The step-up variety.


Anyone ever fix one of the Sony inverters?
Tokin S405-b001-z1-0 ???
Rather hard to tell what's what.




Can you find a datasheet on the inverter IC?
They usually have a circuit that's close to the end product.
