Hi

I have been listening to records quite happily on my Beocenter 4600 and today I turned it on and there is no static sound at at all, no sound with a record and no sound when I put a cassette in to play either. The little run of lights on the right hand side come on when I put press the On button but then go out one by one. Anyone any idea about what might be wrong?

Thanks  - would so appreciate some help.
