If it's a microcontroller, you'll also need the firmware and some way to program it. But those parts rarely fail. Make sure it's not something trivial like a bad power supply or reset circuit.

I already tested all of the sources everything works more he/she doesn't leave sound, in agreement with the manual service of the apparel in the pin 54 of this ci should have reduce to zero volt and he/she doesn't have, in that case I must change him/it, they put has a memory ROM where this his/her programming.....
Actually I need another new ci even......
