Digihome DTR80 freeview recorder - no sound?!?

My Digihome DTR80 freeview recorder no longer produces any sound!

Since plugging a scart cable back in after using it for a DVD player, sound is no longer fed to the TV. Guessing there's a problem with the scart connection.

Is this fixable at all, is it possible to replace the scart connector? Or maybe there's another audio fault internally? Is there anywhere/anyone that fixes these?

I've got loads of good stuff recorded on there I don't want to lose, plus they're quite expensive to replace :-(
