Yamaha Rx-v765 shuts down 30 - 45 min after being turned on. Tried different speaker configurations to see if I had a short in a speaker wire with no change in results. Receiver runs great when I have a fan blowing on it - I ran it for several hours It ran until I shut it off. Receiver sits in an open shelf with 8 in above it, 18 in or so on one side and 6 in on the other. Front is completely open. After shutting receiver off, I have to reset protection circuit by unplugging for a minute or so before receiver will turn back on. Any Ideas?

Hi Russ, Welcome aboard the Shack,

Have you tried leaving it on with no speakers plugged in at all? Do you have it on top of any other equipment?

Hello,
Russ, what kind of Speakers are you using. Also, have you run YPAO (Yamaha's automated Speaker setup) In addition, what level do you usually listen to your Yamaha at?
Cheers,
JJ

Thanks for the inquiries.

Yes, I've tried it with no speakers plugged in. I also tried it with just the front speakers, with just the mid speakers. I've tried it with and w/o HDMI connected, I've tried it with nothing at all plugged in. The only way I can keep it on is with a fan blowing on it. It is not stacked on any other equipment, nor do I have any other equipment stacked on it.

Speakers - front are Klipsch RB61's, Mids are Klipsch in the ceiling speakers. Front center and rear are cheap sony speakers, front is a CN100 (80w), rear are SR100s (50w). Subwoofer is an Infinity PS28. Sound level is -15 to -25 DB reading on the Yahamah. I have not run the YPAO yet.

It is starting to sound like there is an issue with the receiver. Is it under warranty?

**Russ A** · **03-20-10, 12:20 PM**

I'm not sure if there is a warranty on it - I bought it on-line. Another input regarding this problem - I had a Yahama Rx-v663 in the same spot previously. It worked great for a year or so. I then lost the HDMI output. I had it repaired, and it began shutting itself off. It would take several weeks, then it would begin shutting itself down with increasing frequency until it became unusable due to the hassle of continually resetting it. In the repair shop, they could not duplicate the auto-shut downs, although they can see where it has been shutting itself down. They cannot tell why it shuts down. I find it curious that this is the second receiver I have that is having an auto-shut down problem. I thought I might have a power input problem - I have used various outlets in the room, with the same results.

Do you have a voltage tester? see what voltage you have at the plug-in. You should have between 105-120volts

**Russ A** · **03-20-10, 12:37 PM**

Using my very old voltmeter with a 300V AC scale - reading right at 120v , thought I saw 122 for a little while. That is in the "Monster" power stirp I'm using. Reading at the recepticle itself was 118 to 120.
