And Fran, the key works only when I push it all the way i can to the left and push it, it works, but sometimes when I release it it sounds very loud, but this doesnt solve it because it is kind of hard to play on the keyboard and when i need to hit that key i`ll need to use two hands and its kinda hard, but thanks for your idea, I`ll try to wiglle it more maybe it will work.I tried sliding a plastic card between the keys, i felt some bumps(Resistors probably),but didn`t fix the key.
And dont forget guys its a black key, does it make a difference in fixing?
And also i couldnt find that waranty paper that i had.
And thanks (alot) for help, any more ideas?
