For some time, the glass doors of this sytem started to Work.
Yesterday, i listened to the system and shut it normally.
This morning, when I was going to listen to the radio, the system did not react, neither to the remote control, nor you approaching. I tried to turn it off and on several times. After having been turned off for some time, I turned it on Again, and the glas door opened - and closed Again. After, there has been no reaction on tryes to turn it on.
What can be the reason?
