My favourite Beocenter 7700 has ( suddenly) a not reacting and or functioning display.
The manual buttons are not functioning, neither with the remote control, so NO command is coming through.
Stand by light is on . so current 220V is coming in.
The record player does (shortly) react on its pressbuttons, and a ( activating) sound is heard in the speakers. but ther is no other function.
Anyone who can help or advise in this matter. Thanks
