Thank you for your very fast response, really appreciated. All the fuses have been checked and sadly all were ok.

Dug this out , and shows a fuse in the engine compartment for " 13 15 A Sound signal " May have been missed on checking ? https://fuseandrelay.com/citroen/xsara-picasso.html

Hi All, Problem is solved! Found that the speaker wires in the drivers door were shorted together as they had got caught up in the window mechanism. Fortunately when this happens the radio seems shut down it's output stage rather than letting it self destruct. Many thanks to all help received.

Good you found the fault . Thank you for updating the forum , may help others
