I pluged in my Behringer VMX200 (Mixer) to the wrong voltage.

So I pluged my Behringer mixer to a 220v power outlet here in Chile but it was the US version.

I opened it and checked on everything, the fuse was broken, I changed it and it still doesn't work.

This is how everything was.

The first part seemed OK.

Next it was connected to a power transformer (it seems OK as well).

Then this part which is all the outputs on the back.

And from there to the big board which I think is where the problem is.

That kind of looks fried.

There is a knob in the other side.

There are some few other places that looks a brownish like that but not as much as that knob.

I have no knowledge in electronics apart from building a pc and changing modular things in my phone haha, so if someone could tell me what the problem might be or how to check to eliminate other possibilities it would be greatly appreciated.
