Yamaha RX-V2700 Shuts Off Sporadically! Help!

Greetings! My new RX-V2700 shuts off all by itself... which it turns out is really annoying. There's no rhyme or reason to it. It'll go days without a glitch, then shut off three times in an hour. It's mostly used for home theater, so generally when it shuts down it's running a DVD or cable TV input. I don't play it at excessive volumes (no, really). I rarely play it above "-24" for what it's worth. The volume never seems to be a factor anyway. Nor does how long it's been running. Sometimes it shuts off after 15 minutes. Other times it'll stay on all night (I've been leaving it on unattended with nothing playing -no sound output at all- overnight just out of curiosity... will it stay on or not? 99% of the time it stays on). It doesn't happen during "loud" passages. It's not like it suddenly can't handle an explosion or laser blast... it's just as likely to happen during quiet dialogue as it is during the opening of "Revenge of the Sith." It just quietly clicks off at random moments. There are no warnings or error messages. I thought it was the crappy speaker wire I had for my surround speakers. I replaced those runs with 10g wire, and it ran fine for a week... then shut off three times over 36 hours of non-continuous use. Literally, it ran perfectly for 5 days, then one evening shut off twice in an hour (while watching "The Verdict," a film whose loudest sound effect has to be Paul Newman slamming a phone down); ran fine for another 24 hours, then shut off during an unattended nighttime test run. Before I changed the speaker wire, I left the surrounds disconnected for 4 days. The receiver didn't shut down during that time... but again, it's gone just as long with them connected, so I don't know that this means anything. The receiver is in a cabinet with an open back. It has over two inches of ventilation space on top; an inch or so on either side. I've double-checked all of my connections, but that being said, I'm gonna' check them again. It does not seem input-specific at all. Speakers are all set on "Small" (despite the defaults going to "Large" after running YPAO); they're all 8ohm, and the receiver is set accordingly. Since there's no internal fan, I'm not sure what to do to help it run cooler... raise it up some? Help it draw air in through the bottom? I can't see the point of putting a little fan near it... it may cool it off, but I don't want to blow dust into the box! It is as it shipped. I haven't done any firmware upgrades, nor have I done a hard reset after personalizing the settings. Oh! When it shuts off? It almost always comes right back on. On two occasions (since February) it's been hard to get it to come back on... but even then, after unplugging it and waiting a few minutes, it came on and ran fine for days again. This behavior seemed to get worse after my recent vacation. I use the unit every day for at least a few hours a day. Obviously, I didn't use it at all while I was away. Upon my return it shut down more often... but after the point I disconnected then changed that speaker wire? It mostly ran fine, and continues to run better than it did before I made that change. ANY help anyone could offer would be greatly appreciated! While I obviously don't relish the idea of taking it to a service center, I would... but the only ones w/n driving distance have terrible reputations! Thank you!

    I'm definitely trying the "fan option..." dopey as it seems.

    Even with all of the info I provided, I see I was unclear! When the receiver shuts off? It never turns itself back on. I wait a minute or two and turn it on, and see what happens. Normally it runs and runs for hours/days. Rarely it'll turn on... and shut down w/n seconds... only to eventually turn on and run and run for hours/days again.

    Hey! Thanks for the helpful, speedy reply! I'm still open to more suggestions!

    Hi, My 2700 does a similar thing. I have found that it turns itself off when using a DVD playing at -25db on the same part of a movie every time. (HDMI input) It does not shut down at lower levels. It also shuts down when playing my sons PS2 thru it, (Optical input) but I have not experienced the problem with other inputs, ie CD (optical) DTV. It's off to the service centre for my unit.

    Oddly, the problem disappeared for a few months, then reappeared with no warning. The only change in that time was that the unit was left off for two weeks. Since that time, it's difficult to turn on, but once on remains on. To turn it on, I have to try to turn it on, watch it fail, unplug it, wait... plug it back in (at the back of the unit), and try the process again... and again... 'till it stays on. No idea why this is happening, and since I don't have any authorized service centers w/n 50 miles, I'm at a loss for now....

    I have the same problem with an RXV2095 and was wondering what ever happened to your issue??

    My JVC works well but it powered up by itself during the night. A friend believed it was a remote problem, that the sleep-timer was on. He came over, disconnected the TV at the wall outlet, waited about a minute or two, then started the set. We tested it. It went on and off at the touch of the Power button on the remote. All was well for about 4 hours and the TV shut off by itself. So the problem is back and I'm at my wits end. What is the problem and how can I solve it? Bea.

    Mine seems to drop out when the surrounding room temperature is higher than normal (eg. middle of sumer, or when the heating is on in winter). It seems that the HDMI circuitry is overheating and failing.

    I have read on other forums that the same thing is happening to othre people. I certainly expected more for a £1000 amp.

I know for a fact that there are 100's of solder connections in this unit but chances are very high that there's one or two places that are losing their connection do to poor solder.

I've been troubleshooting for over 25 years and this is the Numero Uno problem when things such as this occur.

Find someone qualified to open it up and take a good look at it.

I've had the rx-v2700 shut down during laser blasts to sudden thunder claps. i went into the sound controlls''option'' and set it on zone 3 amp. zone 3 variable, ''messed'' around w/the vol. and init vol while listening at -29.0db. it seemed to work well, tho it did shut down during some star wars passages, but i was able to turn it on w/remote. i've never exprienced a shut down as you described, and my unit has been on 24/7 for 2 yrs.

Same exact problem - - one time i left it disconnected over 24 hrs and it started working again-

now again a year later its happening again-
trying to disconnect everything from ever connection and see what the !@#%!@#%!@-- nope same problem

saw this elsewhere:

If it is going into protection mode even when there are no speakers connected OR when the sound level is very, very low or zero it is not good news.

Yes, unplugging the line cord will cause the protection system to reset itself. But, if it shuts itself off again soon after rebooting it is a sign of bad grease in the output stages -- in all probability.

Let me explain: The audio output transistors are mounted to a large heatsink which keeps them cool during operation. They are electrically isolated from touching the heatsink by an electrical insulating washer. But, in order to keep them cool and allow for good thermal conductivity of the heat generated by the output transistors the washers are treated with a heat conducting grease. Over time this grease will dry out and lose its heat conductivity ability allowing the temperature of the transistors to rise; as the heat goes up they conduct more current and cause the protection system to activate and shut the set down (in order to avoid damage to the set).

That is the most common cause of your symptoms. However, there are several other possibilities, but I give this explanation a 90% probability based on my experience.

My RX-V2700 started with all the above problems and just got worse and worse. To the point it would not turn on at all.... it was completely DEAD.
Took it to a Yamaha Service agent, surprisingly it worked ok for them. They keeped it for 3 weeks, doing tests.... In the end i picked it with a $230 bill and one replaced Poly Cap on the Sub Power PCB. Took the unit home, plugged it in, it worked ok... That night, the unit faulted while on stand-by... and faulted bad enough to trip a 16A circuit breaker in my switchboard. Now in the morning, not more than 12 hours after i brought it home, the unit is completely DEAD again.
Such a shame, and waste of money and time!!!
I agree with the above, it would be so easy to have a dry joint or fault on the PSU somewhere....
I think the worst part is, not even the Yamaha Service Departments know what the issue is...

I have the same problem with my unit. It stopped altogether on boxing day.I returned it to the supplier and they say it is due to a connector in the power supply but time will tell.

These sort of issues are almost always down to hardware faults; occasionally firmware issues. Sometimes a dodgy power supply can be the problem, spontaneously not providing enough power to keep it running for a moment - and then catching up milliseconds afterwards (causing it to turn back on). Heat is always an issue to check for, your best bet, without taking it apart is to try and cool it externally (even if it looks stupid having an office fan pointed towards it) and see if you have the same problem. Check for firmware updates (if there is such a thing available for this device). If this is to no avail, check out your warranty status as this would most likely be covered under it.

    In most cases, when a unit like that turns itself off, it's usually down to a safety feature coming in to place to shut it down to prevent any damage. However, since I am not familiar with your unit, I can't provide any in depth information - but only general troubleshooting tips for units such as that.

What kind of up-grades are for the yamaha


There are no "upgrades" however, if your having problems with HDMI switching or "not working" You can send it to Yamaha and they will replace the HDMI board at n/c. It's still version 1.2 and the current version is 1.3a soon to be 1.4. What is it that you need to have upgraded? Post a comment with what it is you would like your receiver to do and I can help you further. I work with Yamaha daily
