Onkyo receiver/amp model:TX-SV313PRO,year:1996 one day the customer
turned the unit on and there was no audio ouput only a burning
smell.Upon troubleshooting I found that the following parts were
defective:

Q507=2SA1695 (was shorted)
Q505=2SC4468 (was shorted)
R515=8.2 ohm,1/4w (visually burnt and somewhat higher resistance)
R531=2.2 K ohm,1/4w (visually burnt)
R519=0.22 ohm,5w dual emitter (cement metal) (open on one end,I think)

So I replaced all those parts with exact replacements,there is still
no audio output on any mode or set of speaker outputs,I noticed that
when I turn unit on on the main power supply relay engages and not the
ones on the output stages.I measured most discrete passive components
with my Fluke series II DMM model 29 on low ohms (diode range) and
most parts seemed ok.
Anyone have any common repair tips for me from all of those repair
tips sites?.Thanks in advance for replies.
