Re: Centre and left speaker cutting in and out

Hi. I have a SONY STRDB930 receiver and the rear speakers started cutting in and out, with a clicking sound. Eventually, the centre channel followed suit. I turned the receiver over and removed the slotted panel on the bottom. This allows you to access the circuit board, where you will find the solder joints belonging to some blue relays that you can see down on the bottom if you shine a torch in from the top. Check these, as I found 4 of them appeared to have broken. The solder blobs should appear shiny, without any dark ring around the pin. If they look dodgy, re solder them. I did this, and it appears to have fixed the problem, at least for now. These relays are what is clicking, and they turn the speakers on and off. If the voltage supply to the coil of the relay is interupted, by a faulty solder joint, for example, the relay will cut out.I hope my solution is not too late for you, I have only just gone online recently.

Why is my centre speaker not working on my stereo setting on phono?

Records are binaural only. There are only two channels of information, left and right. There is no signal available for a center channel.

Speakers not playing

The problem can be the cable or speakers or RX-V463 or settings. Need to check one by one.
Set the RX-V on DTS or Dolby Digital
1) Check Cables - connect the 2 (surround) cables from RXV's Centre Out to Centre speaker. If the Centre speaker works, then cables are ok.
2) Check speakers - Connect each Surround speaker to RXV's Centre out. If it works Speakers are ok.
3) Check RXV - Set it on DTS or Dolby Digital
Connect RXV's surround out (one at a time) L and R to the Centre speaker. If there is no sound, the problem could be RXV's settings (I need to read the manual).

Hope this helps.

No sound on right speaker channels

If the receiver has not been used for some time, the symptom you describe may mean that switch contacts have become corroded or tarnished from lack of use

I have a sony str de-475 amplifier and the centre speaker stops working after about a minute. leave amp powered down for a while and it works again but only for about a minute

Try replacing the center speaker with one of the left or right speaker and run it for sometime ( do not connect the center speaker to any other channel ). If the system does not cut off the center speaker connection this way indicates a short in your center speaker.
But with the L/R speaker if the system still stops working you have a hardware problem and will need professional help to fix. 5.1 amps are complicated and difficult to access even for an experienced technician.

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.

STR-DB930 Receiver

Hi. I have a similar problem, where the rear and more recently, the centre speakers cut in and out. The relays that connect them click on and off rapidly, like morse code! Annoying, especially losing the centre, as in a 5.1 mix the centre carries most of the dialogue. The voices will be very hard to hear without the centre speaker. I tipped my STRDB930 over, and removed the slotted panel under neath. This gains access to the under side of the bottom circuit board. There, you will find the solder joints of the 3 bottom relays, the fourth being mounted on a narrow strip of board above this. Shine a torch through the top onto the blue relays, and you will see where the solder joints are. I noticed that 4 of these joints looked like they were broken, so I re-soldered them. The centre seems ok now, although it's too early to tell. My receiver still clicks, but if that is comming from the relay mounted higher up, I don't know how to gain access to this easily. Hope this helps.

SR4300 Centre Channel


Try another GOOD speaker on your centre channel.
If the buzz ....buzzes off, it's a bad speaker.
If not , It's in the power amp section on the unit.

Volume and multi channel output issue

Hi there. Are you familiar with board level repair for such products ? Your problem is most likely hardware. Either some of the final output transistors are fried, or it's a dsp problem, a regulator, a diode, a transistor in the circuit.. it could be a lot of things. But if everything was working fine and it quit someday without a change in the system's setup, it really looks like an hardware issue ! Do you have a way in the manual, that sets factory defaults, a kind of reset ? A lot of such units do have that. Try to unplug/interchange speakers as well, a shorted speaker could make the amp go nuts as well, but i wouldn't bet on it. Still, i'd check that out. Hope that helps ! cheebster.
