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.

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.

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.

Is it under warranty?
Have you checked the manual for troubleshooting hints?
Can you bring in another device to try ( is there an AUX setting/plug in back)?
