Onkyo receiver/amp model:TXSV313PRO,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. Sidney Email:sidneybek@yahoo.com Dartmouth,Nova Scotia Canada
