Hi, everyone!
I've been using for many years a very nice SACD player PIONEER DV 696AVS. Fully satisfied by the quality. Few months ago comes to develop a very nasty problem: after powering on, few seconds is showing ON, then is switching OFF and is taking a very long time until possible to switch ON again. Or happens during playing back of second or third audio track. Suspecting some capacitor to be old and exhausted, I did found and downloaded the electronic diagram from net and dismounted the unit, started to search for the "overgrown" electrolytic capacitors in the power supply board A2J003A240. First impression was that C511 / 82microF / 400V been out of order, found a similar and replaced, even the old one seemed to be ok. Voltage before the trafo is around 82V, in schematic says some 130V. Ok, for 2-3 days was working, then resumed to stop immediately after start, just like before. Definitely something in the power board. All diodes in the rectifier bridge are good. Can somebody give me a hint about where can be the problem, or I better start searching for another unit which is still working?
Thanks a lot.
