Do you know where can I find the pin-out of the 2nd monitor conection?

Of course!

Done.

Also cleaned.

I tried every slot and every possible combination with the carts I got.

O_o omg... I hope not... I had already powered it on/off a couple off times before w/o problems, it just stopped working when I swapped carts.

Anywhere where I can find a manual of the PCB or cab with the conector pinouts?

Sorry for being such a pain! :)
