Re: won't turn on!!!! I need my music.
Not a locked mode, your receiver is in the protect mode.
Try disconnecting the speakers and see if it turns on and stays on. If it does, yu have a bad speaker connected. Then you need to start connecting speakers one at a time, turning the unit off to plug a speaker in and then turn it back on after the next speaker is plugged in. When you get to the time when it goes back into protect, the last speaker you plugged in is bad. Take it in to be checked and fixed if possible.
If the unit goes into protect with all speakers disconnected you have a problem with the receiver. Most of the time it will be the amplifier circuit, sometimes other problems. In any case, it will need to be serviced by a professional technician. Sometimes these problems can be fixed for as little as $65 if it is very minor. In more severe cases it could go up to $200, it just depends on what the exact problem is and what kind of rated the service center charges. I have seen these type of receivers sold on ebay for as little as $75 used. That may not be a bad option, because you should be able to use your speakers with most any other type of stereo receiver.

Not following... This is what I think you may be saying: You can't get the TV to use the RCA input?
The reason for my confusion is "rca surround sound". RCA will only carry left and right channel (stereo). It can't push surround sound unless it's setup as a direct input [typically an 8 channel input, where you would have 8 RCA cables (or 4 pair) connected]. The headphone jack, if using a 4-pin headphone jack (it has 4 sections of metal, vs a 3-pin, which only has 3 sections of metal), may be able to send something closer to surround sound, but it wouldn't be a true surround sound. You would need to use fiber optic, HDMI, DVI, or digital coax cable.
The sound settings in the OS on the computer need to be set to push the surround sound, or it will only push stereo. You'll probably need to spend some time there testing all the setting options.
I had the same problem. Found the fix in this document STR-K880 service manual On the amp, while powered off: "While depressing the INPUT MODE button, press the POWER button to turn on the main power." You may need to do this more than once. This switches command mode between AV1 and AV2.
Press the surround button and change the surround mode to Dolby Prologic Music or Movies.Since there are only 2 channels in your MP3 disc and music cd the systems default setting is stereo. Use your DSP ( Digital Sound Processing ) function to create 5.1 from 2 channel source.
dear friend. try to push the surround button. and select movie or music. else you can try reset from the main menu pressing setup the unit to factory settings. if that not work the problem maybe is on the amplifier unit.
Open up the receiver and check for poor solder connections @ the spkr junctions.
If you can solder, then solder a pin that is THICKER than the wire to it, the Bose wire is fairly thin and the spring clips don't clamp to heavily to thin stuff.
When you push the surrounds in you bottom them out in the connector. Having a thicker wire will eliminate the problem, use a piece of 12ga solid wire from house wiring. Make as many as you need and shrink tube all connections after soldering. Use White for + and Black for -.
Hi, Most notebooks have a 1/8 female plugin from your audio card. (headphone Jack)
Now, you need a cord with a 1/8 male plugin on one end and two RCA Jacks on the other.
All you need to do is connect the cord to (AMP) RCA in and the 1/8 Jack to you notebook.
Maybe can clarify the reasons you have different output configurations. I worked for Dolby in London for ten years and cinema processing was an area close to me.
To cut a long story short;
The number of factors and different combinations possible for a fully equipped cinema offering Dolby and / or other protocols to the guest is large to say the least even within the Dolby formats.
For Sony to try to offer a range of home units (recievers or tuner/amps/decoders in this case) was to say the least ambitious .but hey!..........who else can give the public what they think they need.,,,good old Sony
I have looked at this unit and it seems the "amplifier section" is used for various configourations and power output ratings vary depending on the configuration you choose.
Stereo 2 ch L+R is 2 x 75w
Surround requires more channels (centre and mono rear) and of course new signal routing to and from these blocks which of course will draw from the modest power supply.
So 4 channel surround will deliver 4 x 50w.
etc. etc.............what you hear are the relays which are reconfiguring and re - routing the signals.
Basically you cant have all the sections working all the time due to cost /design restraints
So speakers A OR B can be used but not BOTH when in surround mode....where the centre and surround are needed. .you cant have A and B at any time....push both buttons an NEITHER will work ....release one button and there you go.............it saves "letting the smoke out of the box".........which you should never do...........cos they never work without it. :)
Sorry for boring you ...............but I think you will find the unit is working just fine.............you could read the manual but that's not too informative.
hold down the enter button and the advanced surround button for 5 seconds or so and the amp will restart, the display will come up and hopefully it will be ok. its often caused by using speakers under 8 ohms, or damaged speaker cables etc
