SOURCE: The subwoofer is not working on our Bose 5.1 surround speakers.

First of all you should never indicate speakers as Large unless they can produce below 20Hz (which is very low), otherwise always set your speakers to Small.

Second, did you also indicate in teh setupmenu that you have a subwoofer? Because if all speakers are set to Large some receivers will omit a subwoofer because Large indicates the speakers can reproduce all sounds even below 20Hz.

So walk through your setup menu, say YES when the sub (SFW) is asked for and that should do the trick.

Hey, yeah that can be frustrating.

When you turn it up do you hear the relay or a clicking sound, then you turn it on and it comes back below the +2db?

Try unplugging All the speaker wires from the unit. Turn on the unit and listen for the click.
after the click, turn it up past the 2+ db mark and see if you hear it click or shut down. If it did not click off, then suspect a shorted crossover on one of your speakers.
2nd test is to plug in One speaker, and test it at high volume, it will not harm it. If it shuts off disconnect that speaker and try another. Only one at a time.
If it works at high volume, you need to isolate one of your speakers and i bet it has a shorted crossover that has been cooked. P.S. If one is bad, suspect they will fail at a later date.
If they all fail, use a friends speaker and try it before sending it to a repair shop.

P.S. i found one on ebay i think you can get for under $100 bucks in the box.

SOURCE: Front speakers no sound!

Most likely you have pressed the speaker AB switch, try pressing it again and see if it works.

SOURCE: Yamaha RX-V2700 no sound from any speaker outputs

Make sure that you have the correct input signal selected.
Also, check if the sound is not muted.
If you have a multi-room speaker switch, make sure it is set correctly to main speakers.

There is no setting that would choose one front speaker to work differently than the other. The amp or something in the audio path within the receiver is failing.

You can reset the settings to factory defaults via the Advanced menu - it should be in your manual (I have RX-V465).
Do it from the standby mode.
Press the STANDBY button on front panel (not remote) together with STRAIGHT button on the front panel. Now you are in the Advanced Setup. Scroll to the INIT menu and select ALL.
Now you will have all settings in the default.

Hi.

Looks like the the unit is locked to region 1.

The Yamaha receiver you listed is region free, therefore I assume you are talking about a different unit, in that case give model please.

If you have the problem with a Yamaha RX-V661, then simply disconnect power cord for ten minutes. And disconnect from power all devices connected to the receiver.
This should reset the system.

Let me know in case it does not work.

Regards.

theb best way to do this is to connect the DVR to the vhs unit and the vhs unit to the tv using red white and yellow for both connections. usually composite video 1,2,3 or 4. DO NOT involve the AVR at all, as it will cause your video and audio to be out of sync.The video will not be as sharp, until you play it threw an up-converting dvd or AVR.
