Well, i can only say i cut the jumper for the voltage crash. After that i screwed it of the top casing so i could chek the back, while the jumpers were linked again with two wires solderd.
After that, the Casio started tripping, making no sounds, and sometimes a crash sound. My adapter went dead after that, and on batteries it doesnt work anymore. I only rememberd poking around with a piece of metal at the solder points, but thats about it, i didnt forced anything, just gently touched
Is there a SA rerscue team? damn! i think its dead!
(and thanks no:signal, but i wasnt even up to that point yet! l)
I tried other adapters...but no signal or sparks or anything, could the power-routing or whatever be broke in the casio?
