Question about Pioneer VSX-D2011 Receiver

Open Question

Sound cuts out on Pioneer VSX-D2011S, getting more frequent.

The sound started cutting out (both on speakers and headphone) a few months ago, with no error messages (display continues to work normally, responds to selecting different inputs, turning the volume control, etc). When the fault occurs there are no crackles or pops, the sound just stops, almost as if the mute has been activated.
To get the sound back, I have to leave the amp unplugged for a couple of hours, then usually the amp starts working again.
It has been taking less and less time for the fault to occur, until finally tonight I got no sound at all after power on.
I have checked the main voltage regulators, and they seem OK, but I have no circuit diagrams to do further checks.
If anyone has any circuit diagrams for the VSX-D2011S or has any advice on further checks I would appreciate any help.

SOURCE: Pioneer VSX-36TX popping and crackling during warm-up period

I have the exact same amplifier with what sounds like the exact same problem. I opened up the amplifier, and while it was powered on started tapping around until I heard the popping and crackling suddenly increase. I was using a piece of wood and the plastic part of a screw driver for this. The popping and crackling suddenly burst out onto all channels when I was tapping on the DSP board (encased in a metal enclosure to the very right of the amplifier).

I took off the metal enclosure (with the receiver turned off, of course :), and with the receiver on, and started tapping around the DSP board, and I found that the biggest crackling effect was achieved when I tapped on the Cirrus Logic CS493292-CL chip which does all the decoding and switching.

I detached and took out the DSP board and looked at it very carefully but of course couldn't find any bad connections. I tried resoldering all the feet of the Cirrus Logic chip and many many components all around to no avail.

Finally I tried applying pressure to the chip while the popping was going on, and it stopped. Further investigation revealed that bending the board around the chip produced the same effect.

For the life of me I couldn't figure out why bending the board eliminates the problem, but my solution was to put a piece of eraser wrapped in masking tape and taped to the Cirrus Logic chip, and two other pieces on the back of the board in such a way that when the metal enclosure was replaced onto the board, it put gentle but firm pressure onto the Cirrus Logic chip and at the same time bent the DSP board slightly.

It's been a few days without popping, clicking or static, but time will tell. Good luck!

SOURCE: my pioneer vsx-d507s keeps turning on mute

I have had the same problem, since there is no "mute" button on the receiver panel. My power cord on the receiver was plugged into my cable box and I was told this is not correct. I unplugged the receiver from the cable box and plugged it into my power surge protector and no more "mute"!!! Hope this helps.

SOURCE: My pioneer vsx-519V-k amp won't turn on. Just

Have you checked within the set, the fuse and if the standby circuit is working. thre could be a failure of this sub votage which is required for the switch on of the main power. If you do not have any standby indication you must check this section, however if you arre getting the standby you would have a failed output or a shorting that is triggering the error amp to swtich off. If you are familiar with the circuits you can check but I would suggest that since you will need more experience to look into the main board for tracing the fault. In such case check for the service centre nearest to the place you are in using a google search for Pioneer - Audio systems- sevice. Helpful I hope. Good day.

No sound out of the pioneer vsx-1121-k


Hello,
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

Pioneer VSX-456 headphone jack problem


No the headphone jack doesn't disable the speakers. There are two switches in the lower middle of the receiver that are labeled speaker A and B. Pushing one of these should disconnect the speakers from the receiver.

Pioneer VSX-D710S and the message SP off and DTS off message appear and I have no sound. Any ideas how to turn them back on?


The SP off message is the setting for turning the speakers off while headphones are connected on some Pioneer models. If yours is one such model, hold down the RECEIVER button and press the SPEAKER (text may be written above another main function) button on the remote simultaneously and the sound should return.

Sound cuts out


No, this sounds like a speaker problem to me.
It sounds like the voice coils in your speaker(s) have been fried.
What happens is the part that is burnt does not funtion, but as you increase the volume/voltage the speaker "jumps" foward to a section of voice coil that is not as damaged.
Check your speakers!

Sound cuts out.


I had the same issue with the front right speaker randomly cutting out. Thought it was a loose solder joint however upon taking it apart i found that something near the back panel was shorting out. While apart i found that wiggling the rear panel would cut in and out the speaker. Also the fan would turn on when the speaker worked, which until i took it apart i didn't know it had a fan. I removed the back panel by taking out several screw the hold the cable plug-ins. once the panel was out i insulated it with electrical tape then used a utility knife to cut out all the cable connector holes. I also took out a couple screws on the main board so i could lift it a bit from the back and ran electrical tape over the solder point for the speaker connectors. Put it back together and haven't had any cut out's since. I now notice that the fan now runs all the time exept when i press mute. I also hear a single tap noise for a second when i mute or turn off the receiver. I can certainly put up with that though. Hope this helps someone else, I put up with the speakers cutting out for 6 months before i got around to taking it apart. Also those bannana plugs are a rip off, I went to future shop to buy them and couldn't beleive they were 25.00 for two pair. That would mean it would cost me 75.00 to do my 5 speakers. Thats more than i paid for my dvd player. anyhow i didn't buy them and just used bullet connectors, pack of 10 for less than 5.00, not made of gold but they work fine.
