Question about Sony DAV-S500 System
I got a DAV system that had exactly the same
problem, ie. it was stuck in "headphone mode", this mode should be
active when headphones are attached then it should revert to amplifier
mode when the headphones are removed.
I opened the cover and removed the amplifier output board (the one where the speaker wires connect to) and soldered the following dry joints.
1) large brown capacitor on the amp output board.
2) dry joints on the rear headphone socket (the one that has the connecting lead from the front headphone socket)
3) Then one of the surround channels didn't work so I soldered further dry joints on all the coils (white vertical rectangular blocks)
I tested all surround chanels before putting the lid back on (careful, watch the mains) and found all was now working ok.
