Hi,

I own a Beocenter 7700 which worked fine till yesterday. When i put power on, the Display shows zero 0 on the volume level, and P on the right side (where is indicated the sound source normally). The rest of the display went dead. All the buttons can be pushed without making any change to the situation. The plate of the turntable is spinning, but very slowly, the sound you hear is the one of the radio with no station choosed.

I checked the two fuses on the bottom of the Beocenter, as well as two fuses i found when opening the right side of the Center.

Does anybody have an idea what the problem might be?

Thank you very much for your help.

Claude

Typical symptom of a processor that's not running.
Check the processors reset signal and supply voltages.
