    Thanks Premtech!
    I figured as much that somehow something must have burnt out the IC... uhhh too big to put in the car so will have to see who will come over and have a look! but Many thanks! at least I can still hear something thru surround.

Wow, this is a model Toshiba built specifically for the European market and we see nothing like this in the States. According to the Toshiba index it's even a popular unit in Russia...
That said, I'm guessing that the audio Ic has failed. It uses a single stage series circuit stereo amp and you mentioned using it in surround. Being attached to an external amplifier through the unbridged source or unamplified source is about the only way you will get sound without replacing the amp Ic and you might also check the caps using an esr meter while you're in there...
Hope this helps!
