Center Channel not Working

Center channel mysteriously stopped working.  I've confirmed that it's the tuner and not a speaker problem.  Have toggled settings on and off and still no sound coming out of Center.

    While I keep a press at the back conectors I can clearly hear the relay and the center channel start working again. I removed the cover and inserted a little wood object between the relays to constantly have a pressure on the relay, but since a few days it stop working. Im almost sure is a cold solder connection, but it is very difficult to reach the solder side of the board..Today Im going to dissasemble, if I destroy it, it was time to buy another receiver...

    Are the rear speakers working on whatever you are trying to listen to?

Check that it's center speaker in the set-up menu is on and that the sound field that it's in uses the center speaker. try it in pro logic. It could be a bad solder connection on the speaker terminal or on the relay in the receiver.

Receiver says center channel unavailable


It may be the surround mode you are in. Some modes do not use the center channel. Try changing to a pro logic mode, these will almost always use the center

Yamaha rx 530 center channel cuts out


Thanks for all the suggestions guys.

I've tried using the balance for left and right speakers, and when the receiver is acting up with the right speaker having a low volume, I tried moving the balance all the way over to the right speaker. The right speaker volume will not increase in volume but the left speaker will decrease in volume.

Just to clarify, the center and the rear speakers are balanced. The issue only happens sometimes when I first power on the receiver I will have no center channel. If I leave everything alone for a few mins, the center channel will come on.

So it seems to me that something one the receiver is going. The question is, can anyone suggest a physical repair for the receiver for these symptoms?

Thanks

NAD C740 Chanel B Speakers not working The speaker output A is working properly, then the output B is completely silent. I install differents speakers and even the same speakers. no sound from the B...


possibly the causes are: 1. defective channel B power amp board. But try operating first with the built in tuner, if it's ok the RCA cable from your other sources(DVD player, etc...) might have broken internal conductor.
2. if it has the speaker switch(A, B, A+B) try toggling it, might also just loose contacts.
if the trouble is #1, leave everything to your trusted qualified technician, he knows what to do, unless you want to tweak/repair it by yourself...hope this helps ;-)

In dolby digital mode i can not get any voice volume. All other sounds are ok


Assuming that you mean Dolby digital 5.1, confirm that you have a center channel properly connected and perform the following;

Using the remote, enter the menu on the receiver and navigate to the selection labeled "LEVEL." Toggle through the selections until you reach the "CENTER CHANNEL". You will be able to use the remote to increase the volume of that channel in .5dB increments.

Kenwood VR-507 Now only get sound from 1 front speaker. all other speakers have stopped. Have not changed anything.


PROCESS OF ELIMINATION: connect each of the other speaker in the working to check to see if the wires and other speakers are working. If all speaker play when connected to the working channel check all other cables and connections....use the tuner as an working source to test. If that doesn't help then you may have an bad channel in your amp and may need to be repaired.

Centre speaker


The controls I would check are speaker set-up and configuration for a multi-channel sound, be sure to enable center channel YES/NO option and trim center channel level output.

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.

Center channel


Just to rule out the easy solutions, have you made sure no settings changed? Make sure that you didn't accidentally turn off any surround sound settings or turn off the center channel in the MCACC setup or the like (I have the VSX-D814, so your receiver should have MCACC as well). If you're sure no settings changed and the center channel should be working according to the receiver, then it would appear that the center channel amp went out in the receiver. You can either get a Pioneer service center to take a look at it, or if you're comfortable with electronics, I believe you can get the parts straight from Pioneer.
