My Yammy 1700 Randomly Shuts Off

[bluto65]

I'll try to stay brief but I have an issue with my Yamaha 1700 receiver randomly shutting off. It currently drives my HT including my Ascend Acoustics 6.1 set-up, my Panasonic projector, cable, and dvd. It is plugged into a surge protector/power conditioner that indicates everything is fine including proper grounding. I have read the limited literature that comes with the receiver that indicates the receiver has a self initiated power protection system that will shut it down in the event of unusual power surges, for overheating, a shorted speaker connection, the power cord not being totally connected at both ends, etc. However, I have gone over the system to try to verify that none of these are a problem. I know overheating is not the issue because the unit has shut down 5 minutes after being turned on. Other times it has played for hours. Normally it shuts down about an hour into a movie. The unit was purchased new back in December but wasn't connected until I finished my basement in April. Any ideas? I really don't want to disconnect all my inputs to send the unit off if it something I am overlooking. Thanks for any feedback! Cheers.

Welp..I've got the 2700 and mine would shut off on me when there was low bass. It was due to the low impedence that my Legacy Audio Focus 20/20's hit when certain frequencies are produced. You may want to see if any impedence checks were ever done on your speakers and if there are any dips down into the low 2ohm or even 1ohm areas...if so, that would be what is making the receiver go into protection mode. I ended up just getting a seperate amp that I power my front speakers with and it hasn't shut off on me since.

Just to let you know...my speakers are "rated" at 4ohm but that is just an average. You can't always go by what the manufacturer states.

Good luck.

What do you mean it drives all these? Do you have them plugged into the AC outlet on the receiver?
What is the speaker's sensitivity and impedance? How hard do you drive the system? Is that a powered sub?

James Mos,
I have seem to watch and noticed that when I have a lot of bass sounds out of my HSU sub that it coincides with a shutoff. I do think think that it may be an issue with the lows. Thanks for the information!

 

[bluto65]

Mtrycrafts,
Everything is connected through the receiver. They are not plugged into the Yammy, everything is plugged into the power strip/conditioner. I will have to look into the speaker sensitivity and impedance but I used the auto setup on the receiver to detect what was connected and the optimum setup. I don't drive the sytem to the capibility it should have for sure. The HSU sub is powered.

Mtrycrafts,
The HSU sub is powered.

Then, it is not a sub low frequency issue. How do you have the speakers programmed in the receiver as Large or small. If the former, reset to small and see what happens.

 

[bluto65]

I have the fronts and center as large and the sides and rear as small. The problem seems to be getting worse. I originally thought the receiver shut down when the sound increased significantly during a movie but it has increased in frequency and randomness. There are times now I have to totally unplug the unit after a few attempts to bring it out of standby mode. My family and I just tried to watch a movie and it shut down about halfway through and I cannot get it to come back on and stay on. Earlier today it quit while watching normal cable television. Sometimes it quits now when I fast forward my DVR. Any change in anything can trigger it, or it may just do it on its own. This wasn't a problem until about a month after we had been using it and even then it wasn't often. I am starting to believe it is an issue with the receiver itself.

From all this, it seems you have internal issues, don't know what exactly, that is failing more and more, hence the randomness and frequency. Best if you just replace it unless it would still be under warranty. but even then, it would be out of free labor and that will eat you alive.

I hope no one thinks I am rude by trying to point out the obvious but, here goes. You said you have checked the connections going into the receiver, how about the wire going into the speaker? A single strand of wire can cause your receiver to go into protection mode and it doesn't necessarily need to be behind the receiver for it to happen. Double check all your connections again, it may save you time and or money.

Please except my apology if you have already checked this, sometimes its easy to over look.

At this point no need to worry about offending me with anything obvious! I appreciate any suggestions. I have done some surfing both here and elsewhere and it appears that I am not the only one out there who has gone through this. Unfortunately for me I have discovered that the place I bought the receiver is not an "authorized" dealer so I am out of luck with Yamaha's warranty (a valuable fine print lesson learned). Anyway, I have gone to the point of disconnecting everything from the receiver and then powering it up, and it works fine that way (12 hours and still on). I have checked all the speaker wires at both ends and found nothing but I plan on putting banana clips on the receiver end before I reconnect. Hopefully I somehow missed something the 10 times I looked over the wires while connected. Obviously this will take a while. I am hoping this may fix the issue but my gut feeling tells me that as soon as the speakers start drawing off my receiver's amp it is going to shut down again. Thanks for the replies.

I would suggest since you have a separate sub, set all your speakers to small in size. I don't know how many times it has shut down on you but I believe each time it happens, it will probably shut down just a little bit easier in the future so if it has been overloaded many times, it may be over-sensitive at this point. Besides that if all your speakers are 4ohm rated, that will most likely over-drive the unit since it really isn't made to handle 4 ohm speakers let alone 7 of them. Best bet is to get seperate amps for the fronts & center and then the unit could most likely drive the sides & rear by itself since they don't get nearly the volume that the fronts & center do.

Have you tried to contact the place you purchased it from? Many times those places will warranty item themselves. Good luck either way.

 

[bluto65]

I'll reset the speakers to all small once I reconnect. I have rechecked all of my speaker wires on the speaker end since I have disconnected everything. I am going to reconnect to the receiver end with banana clips through the ends to help ensure there are no wires touching. I put the order in today so it will be a few days. My speakers are 8 ohm average but I am not sure how low they go when trying to reach the lows. I am considering adding an amp to help reduce the load on the receiver. I have been reading posts trying to get semi-educated on what brand, new or used, how many channels, etc. If I knew this was a fix I wouldn't hesitate but my instincts keep telling me its an internal issue that will continue. I plan on contacted the place where I bought it but I don't feel good about it. I may end up driving the receiver to Indianapolis to the nearest certified Yamaha repair center unless someone has a recommendation for a Cincinnati area repair shop.

 

[James Mos]

So did setting all the speakers to small help at all or have you not reconnected everything yet?

 

[dem beats]

It's like my twin!

Hey brother!

Check out my thread here. I have a very similar issue!

I think I will need to buy a dedicated AMP in the end before I am satisfied... but that happened to me when I heard the differance between a seperate amp and an AV receiver. It had more "life" to the sounds comming from it....

I have resigned to knowing I will need a seperate amp, but for now I will be exchanging my receiver for one that states it can handle hower ohm loads. It sounds like you cannot do that so maybe looking into an amp from videogon audiogon or a superseller on EBAY would work well for you.

Something I tried was to unhook 2 speakers and play the receiver to see if it could push 3 speakers. I could turn it up 2 more ticks, but it still cut off no matter what combination of speakers... unless it was the center and another speaker, then I could turn it up 3-4 ticks.

From what it sounds like is you are going through exactly what I am...

For my Rx-v2700 I ended up getting a yamaha pro amp the P3500S and couldn't be happier with it. No hiss what-so-ever, extremely clean and EXTREMELY powerful. It has no problem driving my Focus 20/20's to levels that I just can't handle. It costs a little more than some other pro amps people are using, but I wanted to just stick with Yamaha. Eventually I'll get 3 more amps to power my center, sides and rears once I finish my home theater but for now I just needed to offload the front speakers from my receiver.

James Mos and dem beats,
I just got my banana plugs from Bluejeans cable yesterday, I am in tedious process of recutting and connecting the plugs to the wires right now. I'll let you know when I get finished what the results are but like you and dembeats I'll probably need an amp to resolve my problem. I actually would be happy with that if I knew that would totally resolve the problem. I guess I need to begin to educate myself on amps! I am running a 6.1 system right now but I know a 3 channel on the center and fronts would probably be enough to take the load off the Yammy. I would really like to be able to stumble onto a good used 200 wpc 5 channel and just be done with it. Thanks for the advice to both you and dem beats.

May I suggest the Emotiva LPA1 amp..will power your system effortlesly and sound fantastic for a measly $500 shipped.

I strongly suspect that your speakers are dipping way too low to of an impedance that the 1700 can handle, this is quite common.

Not to hijack this thread, but two quick questions:
1. Do you own the LPA1? If so, I'd like your impressions.
2. Is there a way to still get it shipped free? On their website, it's at $543 shipped.

Thanks.

Bluto. I can almost garuntee you that a 200+wpc amp will fix your issue. I would make sure it can handle 4ohm loads however. Call the MFG before you decide....

I think a receiver with a better load handeling would fix your issue too, but if you have the money I think an AMP would make you happier in the long run. I just have the chance to upgrade and use the cost of my current receiver towards the new on in total.

Jey Jockey and dem beats,
Thanks for the recommendations. I have done some limited reading on the Emotiva LPA-1 so far. My question is if my Yamaha is rated at 7 x 130 wpc at 8 ohms already then how is the Emotiva at nearly the same rating at 125 wpc going to handle the demands any differently? I realize this may be a stupid question but I am trying to educate myself before I invest. Thanks for the help.
