Its not switched off in the menu is it ?
It doesn't work in some modes if it's similar to some of the Sonys
I've owned and seen.
It should work in a Prologic (or AC-3 maybe) mode, Phantom at least,
hall maybe, depending if Prologic is on or simulated and may not
function depending on how you set any Sound Field settings. I had an
865 and the D611 I have still isn't as fancy but it operates
similarly.
Last consideration is that each amp section has it's own relay I would
bet and there is more than one fused section in there. If you
operated it out of spec if MIGHT be damaged...I've been told by Sony
that it's not recommend to operate A and B simultaneously as it can
and will damage one or both outputs (you can still use the undamaged
section as FRONT and obtain surround if the surround outputs are
okay). You might lift the bonnet and visually inspect fuses, relays
and look for burnt sections first.
An owner's manual might be available from Sony online...they seem to
have regained there senses here in the US even if they were borrowed
and have writing on them. Try eBay, Sony or whomever you normally go
to sitting with a laptop on St.Kilda beaches.
