Question about Sony DAV-S300 System

1 Answer

No audio Everything works on my DAV S300 but for one thing. There is absolutely no sound to the speakers not even the test tone. All of the front panel indicators are ok and the disc tray works fine. It just acts like it is on mute but it is not. Failed after not being used for three months while we were away.I do hear the audio at the phono jacks. I took the cover off and all of the fuses look ok and there is no visible indication.

    ..., ...Polkared ...etc The Box working COMPLETELY(Display,DVD,AUX's,TUNER,SETTINGS -Sound Field ,HEAD-PHONE) OK!!

    sound then the SOUND CHECK is not working too ( Normal) Now my box is
    in pieces, and I try to find out where is the Problem. Its seems to be
    a protection ( I don't know - OVERHEAT , OVERLOAD ... ) If somebody

    Sounds like willy's problem is exactly the same as mine. Works at the headphone socket, but no sound otherwise (though haven't tried the phono out on the back)

    Another thing I have noticed is that it no longer makes the noise that sounds like a relay click when switching on.

    I have checked all the speaker connections, MUTING is not on, and the test tone can not be heard. The loss of sound affects all functions (DVD, CD, tuner). It's as if the surround sound amp is not being powered up.

    I have opened up the box and checked continuity through any internal fuses - all seem fine. Didn't see anything suspicious in there.

    I do have the same problem. Audio only goes out using the RCA outputs Any clue?

  • Juan Alfiero Nov 29, 2008

    No audio on my DVD S300 out of the speakers. The dvd players works ok but no audio, only using the RCA outputs.

    Same surround. No test tone. Audio through TV fine.

  • ellykitch Dec 23, 2008

    I have exactly the same problem willy. Have there been any solutions?

  • rigore Jan 04, 2009

    It was great until the sound stopped working - I have no output to the speakers all of a sudden after 1.5 years of casual use. Now all I can do is plug headphones in when I want to watch a movie. I don't know enough to diagnose it as a blown amplifier, shorted circuit or what - I just know there isn't any output to the speakers.

The sound stopped working. I have checked all the leads. Everything seems fine. Been working for years. Any ideas?

One source or many? Could be the source.

Make sure you have the correct input selected and MUTING is not on.

If the product is protecting itself disconnect all but one front speaker and see how that works out. If it starts working you need to isolate which one is/was the problem.

No sound going to my right front speaker. I switched the center and right speakers to confirm that the speakers themselves are each working - just no sound being driven from the Sony HCD-S300 to the right...

Sounds like you may have a problem with the wires themselves. Perhaps you could sacrifice just a little integrity (literally not enough to notice) by simply tying into the center speaker with the right front wires. That way, at least they're all working.

Sony DAV-S300 volume is unchangeable from either remote or knob. Any ideas?

Is the sound coming from the speakers you have installed, or from the speakers on the TV itself?

I need help with my surround sound!!

The calibration mic thing is to balance the sound evenly on surround sound systems, it replacles the older systems "TEST TONE" speaker setup, in other words it will balance each speaker say in a 5.1 setup to adjust the level output so the listening position is not overwhemled by say the rear surround speaker overriding the front left & right speaker or the most critical the center speaker. The calibration mic uses computer tech to make it easier for the user, no sound pressure calibration is needed as with the test tone setup mentioned earlier. The wireless speaker situation could be possibly waiting for the calibration confirmation, Read any user manual information if available.
