Can anyone help? The above machine isn't as old as the rest of my gear, but it's gone crazy. The controls seem to do what they want when they want, and when it does decide to play music, it may suddenly stop after 10 or 20 minutes! I'm worried that it must be a centrally-located logic fault, but (being a poor pensioner), I'd like to know if anyone knows of any 'quick fix' routine or trick before I have to get a professional on to it.
