Question about Pioneer Audio Players & Recorders

Open Question

I have a Pioneer VSX-4900S. No sound comes from any of the speaker outputs. On the display it does not show what speaker A or B is on. But I can't remember if it ever did.

This A/V receiver has worked fine. I bought it new. FU3 and FU4 are good as well as FU1. Since I have no output, I expect a common problem. The schematic looks like the rear and center channels are driven from a separate source than the front. That confuses me a little. Hope you can help.

SOURCE: No output on main speakers

I have experienced a similar problem with my Sony STR-GX57ES and took it to a certified tech only to find it needed the power supply replaced. I opted to hunt down a compatible power supply but have been unsucessful thus far. That being said I picked up an STR-D665 for next to nothing and found the power supplies to be quite different (you would hope so any, with the ES meaning Elivated Standard and all) but with the D665 working flawlessly I'd rather have something working than nothing. Good luck!

SOURCE: 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.

SOURCE: No sound output from Center and Surround speakers

the only time the center and surround speakers put out sound is when it has a surround sound source such as a dvd etc. and only certain sounds come from them as well.

SOURCE: Speaker output

Yes, there are relay type switches associated with those outputs. Your RX-V1 is not dying.
Just plug a pin plug in and out of the dead channel to bump the switch. You will hear the speaker
come on. If it doesn't come on,do the plug jack in an out of the pre out again. It will come on.
You can use the test tone to check all channels and rebalance volume levels. You are making the
pre out connect to its power amp. It seems the problem got better when activating those switches. Most likely a cleaning issue. You can also jump the mains and center, and there is also
a modification to jump all channels. I bought my RX-V1 very cheap because of this and love it.
Of course outboard power amp would solve all, but getting this reciever to connect to it's own
power amp has been thrilling as far as bang for the buck. I do use the front effects also, and like
them. It may seem like a pain, but it is worth it to get those channels going.

Pioneer VSX-D307 has no sound from right front speaker.


Did you connect a known good speaker to the amplifier's right front output connections? Make sure you also have known good wires for the front right as well. Make sure balance control is set to the middle and not just to the left.

Won't power up; push power button on, hear click in back left of unti, get nothing on front display and no output from speakers; as if unit trying to operate


Disconnect the speakers and see what happens. Carefully examine the speaker cables for unwanted connections (shorts).
Take a clue from when the power problem appeared. Something was moved and made the buzz a (probable) dead short.

Sibilant output from Pioneer VSX 1018 AH-S


Suspect a DTS board capacitor failures the ESR characteristics.

To troubleshoot connected any available device to RCA stereo connections at input to multi channel in. Test input to the corresponding speaker output confirming audio quality. This circuit bi-passes the DTS function and connects to the power amplifier for the speaker.

Connect any audio amplifier from the preamp out and confirm the quality of the audio.

I suspect that the pre-amp out will contain the distortedf noise. If the distrotion appears in all the channels it is most likely the DTS.

These are repairable.

Hope this helps?

I have a Pioneer VSX-4900S that when first turned on (cold) the right channel doesn't work unless I turn the volume up loud or let it warm up and roll the volume knob up and down. From then on it works...


Hmmm, that almost sounds like a bad solder. As things heat up, they expand. When there is a bad solder (even if you can't see it) as the unit heats up and the pieces expand, the contacts at the solder point will meet and allow the circuit to complete, thus producing sound through the right channel.

Take a large magnifying glass, and with it, examine the bottom side of each of the circuit boards, looking for a solder point that is not well formed.
