Question about Yamaha RX-V690 Receiver
I have lost the volume control on my receiver. It shows the text on the screen when I press the volume up and volume down buttons on the remote but the knob doesn't move. I can manually lower the volume by turning the knob. My guess, after removing the knob, is that there is a motor that turns the knob and hopefully a repairable peice. This is an excellent receiver that I'd rather not part with. Any suggestions on how to fix this issue?
On the bottom of the remote on right side, right next to the master volume - key . it is actually called muting instead of just mute. Hope this helps.

SOURCE: Yamaha RX V690 keeps shutting
Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.
Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.
Check for loose speaker connections at the speaker as a possible root cause for intermittent shutdown.

Follow the manuals for it... http://www.retrevo.com/support/Yamaha-YST-SW015-Subwoofers-manual/id/320ag324/t/2/
... and the RX-V690, page 11.

The volume knob issue alone sounds like it's hardware-related and therefore not easily fixed. Also, since the remote appears to be working (the LED's are lighting up), but the unit is not controlled anymore, the IR sensor is probably faulty as well. I would seriously consider sending this AV receiver in for repair. If it's still within warranty, you shouldn't need to pay anything for the repair.

It's not much but I hope this helps.
