Not sure what to do but my sound has started going off in my system. I have surround sound but receiver starts 'clicking' and then I lose my sound for 15-20 minutes. Any suggestions? It then comes back on at random it seems.

Trying to diagnose something like that especially with the information given is impossible.

What I would suggest is researching the model, if it's a common problem you'll find a solution. I had very large Sony Trinitron monitor go bad and the issue was common, parts to fix it was a grand total of 10 cents for the resistor and a few hours work to actually get to where the resistor was. Same thing with a set of Klipsch computer speakers I had, the fix was cheap but for those I ended up sending the board in the subwoofer to the factory because they were fixing them fairly cheap. Apparently they knew they had an issue and that's a high end company that isn't going to want to screw up their name.

Most receivers have "protection" circuitry to shut down in the event of overheating or other potentially serious problem. They often sense the electrical current and if it is too high they shut down. Often a relay is triggered to shut down - and a relay makes a click sound when it acts. Too much current can occur if there is a fault in one or more of the attached speakers or a wiring fault (short circuit).

It sounds like the sound comes back on by itself after being off. Overheating a possibility?

This is my first thought. But in my experience when a fault like you describe occurs the unit turns off. So it wouldn't come back on by itself. There may be exceptions, certainly.

Maybe OP isn't describing the action clearly.

I agree most faults won't reset after some "time off." But if it were overheating it might reset when the receiver cooled off.

I've never seen one that does. I think I may have heard or read that components are designed that way, or possibly I reasoned this out for myself years ago. It's not a good idea for gear to turn itself on at some random point.

I dont think it was overheating as I had turned on the system only a short time before.

Now the sound is out. I had the Geek squad folks come out and they said something to the effect of 'there is no connection to the speakers'.

Its the receiver on my surround sound system, and they were able to get sound directly from the TV, but when connected through the receiver we got nothing.

The unit is a Denon AVR 1910.

Well I took coalmans suggestion and started googling the model number and found a forum for my model and 'no sound'. Sure enough I wasn't alone...and there was an easy solution that I couldn't believe. One poster suggested blowing air into the headset jack. Lo and behold I had sound again. I guess dust got in there and was covering up something. I was resigned to shelling out for another receiver. But now I can watch football again!!!!!

Excellent! One more trick to put in the magic bag.
