fabia radio problem

Hi.

I did not know where I start, let me explain the rough. The car was parked. I went home. Always listen to music while driving, the radio is on. In press and radio off when closed. For Fabia, sound button on the radio is on and off. Anyway, forget about two hours later when I noticed something in the car, according to what I am when I go back, switch off the radio off, although the "tape recorder was running." Open and closed again, still closed. Anyway I went home, started to go back to the car radio that was open ...

So radio is in power off button no matter what, more exactly, to the radio hanging from the button, 5 seconds later the radio is opened again ... I would also remove the channel change button, then the radio does not work.

But this is a problem, what you think is the solution? Why does the radio itself open?

Thank you.

(Sorry about for my english..)
