Question about Arcam AVR-200 Receiver
Most of the time, as you know, it is, indeed, a button/setting issue. Unfortunately, one has to know all the functions of the machine to recognize what's going on. I checked out the following blog, and a fellow had a similar problem as yours, and they simply replaced his unit for free. Here's the page:

In Stereo Direct the analogue sound is directly routed to the amplifiers. In all the other ways the signal is digitized (if it ain't already) then modified digitally in a very specialized processor. In your case that processor has just died. It can't be repaired and you must replace the entire board it's soldered on to fix that - it will be expensive.
Why it has failed ? I don't know, but, since it's a processor, even the smallest electrostatic shock is enough.

probing signal outputs on the receiver.
