Hi Spike, The first thing I would try is to reset the system. Turn off the receiver and then hold down the power button for 5 seconds. "Enter to clear all" will appear in the display. Press enter and "Memory Cleared" should appear in the display. You are now back to factory settings. If this does not work, try checking the fuse. Take the two screws off from the back top of the unit, and the two screws on each side of the unit, and pull the cover off from the back. You will see the fuse in the back right side (if you are looking at it from the rear) Pull the fuse out and see if the wire is broken. HOPEFULLY one of these solutions will fix the problem. Please let me know how it works. Best regards, nightdiver

SOURCE: Surround Speakers stop working

More then likely unit has poor solder connections. Try lightly tapping on chassis to see if you can get audio to either cut on or off with the vibration, If you can unit has intermittent solder connections probably around power amp ic701 where most of the heat is generated. I have a PDF service manual if you need it for yourself or for a technician if you take it in for repair kstahl65@att.net

SOURCE: No sound from rear speakers during test tone usng Sony STR-DE475

I had this problem last night.

To solve it, you can reset the amp by:

1) Put the receiver on stand-by
2) Hold down "MODE" button and press on button
3) "S.F. CLR" appears in the display and surround is back on.


Good luck

SOURCE: Kenwood VR-305 receiver surround speakers will not work

make sure that all input cables are in the correct positon also make sure that any inputs you are using don't have a macrovision in them that will also kill your sound due to copyright laws and stuff but main thing check all wires coming in to receiver and if you need more inputs go to walmart and get a rca splitter basicaly its a 1 in two out connection to add more cables in the input

SOURCE: No sound: The receiver has suddenly stopped giving

That sounds like you blew the fuses inside the receiver. Take the cover off and check them. Typically thats the problem and if I'm not mistaken they are AGC-5 Buss fuses available at your local hardware store.

Why am I not getting sound anymore?


Amplifier issue. See if you are getting audio signal at audio outputs used for recording. If not, then it is NOT the audio amp and the proceeding circuits are responsible.

U might also want to check out your power supply voltages to make sure that the other components are being properly fed.

The sound for my Yanaha RX-V665 suddenly stopped working for all componemts as well as the tuner. Everything comes on but there is zero sound. I have unhooked everything except one speaker. Any ideas


Try the speaker select switch on the front panel. you'd be surprised at how easy it is to accidentally turn it off or switch it to B speakers.

I have no sound coming out of receiver all of a sudden. Connected speakers to another radio and speakers work fine. Everything looks fine on receiver just no sound. Oh, and the mute button is not on.


It is an indication that you have a faulty output ic.
Output ic is responsible for amplifying the audio from your reciever to sound output which is converted by your speakers.

If you're output ic is defective then definitely you haven't sound produce even your unit is working.

I've advice you to look for a qualified technician to checked the condition of your output ic and do some re-soldering for some dry joints on the board.

Thanks for using fixya...

Rear speakers L and R not working and MD in and out not working on my Sony STR-DB940


I'm guessing these are separate issues.

Has either one ever worked and stopped suddenly?

From the manual:
"No sound or only a very low level sound is heard from the rear speakers.
>>> Make sure the sound field function is on (press SOUND FIELD - MODE).
>>> Select a sound field containing the word "cinema" or "virtual" (see page 33-35).
>>> Adjust the speaker volume (see page 72).
>>> Make sure the rear speaker size parameter is set to either SMALL or LARGE (see page 20)."

Be advised that using any Tape Monitor loop (that's what the MD/DAT is) disables any digital sources. Not that that would explain the rear speaker failure. Analog sources can still be processed into various surround modes.

Any Tape Monitor use requires at least a live INPUT to hear anything.

5.1 Surround sound not working


Maybe the surround processor is having a bad day... My kenwood would do similar and a reset was necessary to correct. Have you tried resetting the system? On my Sony STR DE 597 this is accomplished by powering off. Then while holding the 2 channel button down (front face plate) power on. A reset message is displayed. Your model may be similar but check your manual or download the PDF of the manual from Sony's support website. Hope this helps

The amplifier stops working suddenly simultaneously with a sound like turning the amp on or off! I have to turn it off and then back on in order to work again?


disconnect the speakers first to see if a speaker or wire is shorted if it still does not come one you have a blown amp and unfortunately this is not a user repair unless your an electronic service tech.
