Question about Pioneer VSX-C300 Receiver

1 Answer

Losing sound in certain modes

Hi, I have a Pioneer VSX-C300 5.1 Channels Receiver which up to now has been working fine, but recently when it is in Standard mode the unit "clicks" then the sound is al but lost (very faint and muffled). If i switch to another preset mode i.e. Auto the sound is fine (but not the mode I like to listen in!) Sometimes it wil go for a couple of days without a problem and other times the fault occurs within about 10 mins of turning the unit on. Regards, Tym Harvey

    I had the same problem with muffled sound when the centre speaker cut out. Changing to stereo mode sounded perfect. This was caused by several dry joints in the unit, possibly caused by the high temperature that it runs at.

    An audio engineer found and soldered these joints to cure the problem.

    Was getting the clicks, after turning off the unit for little while the clicks would stop. Now it doesn't work at all...I get an overload display then auto turns itself off. Believe the center speaker is bad. I can measure 0 ohms across all speaker outputs except center spleaker..40K ohms.

I get the same problem with my Nakamichi, but it never bothered me much, since i can't notice any quality drop, besides, its only radio. I remember it happens only on certain stations though, which leads me to believe it might have to do with the broadcast itself which oscillates and varies in amplification from station to station, and is affected by weather and geography. If it really botheres you, try getting extra juice amp for your tuner from some specialy electronic store. Good luck

No sound out of the pioneer vsx-1121-k

Try removing all the speaker and the HDMI connections; then use a headphone to listen to music from the tuner or a CD in stereo mode. Better in direct mode. If you hear your music correctly the receiver could be working correctly. If no music is heard, you may need to have it repaired professionally.
If you can hear music, connect the main FL & FR speakers and verify you can hear music that way, without the headphone connected.
If you can hear music that way, connect the center and rears. Try a mode that uses all channels to verify all sound channels are working.
Then, and only then start adding your HDMI connections.
Good luck

Center Channel not working on pioneer vsx-d608

Be sure the sound source has a center channel output ie. not a 2 channel source only, try the test tone setup for 5 or 6 channel balance, if no sound from the center channel still then it is looking like maybe the center channel is blown.

The Sound is Gone.

The circuits that routes all the audio signals thru the amp has either died OR the power supply that runs that circuit has died.
