Yamaha HTR5890 switches itself off

[dread]

My HTR5890 goes to standby mode a few seconds after switching it on. This just happenend i was told by my young bro.(dont trust him though). I have checked the power cable,diconnected it for a while, I cant adjust the speaker impendance coz it goes off before it shows if its set to 8 Ohms or 6 Ohms. But i had set it before to 6 Ohms since i am using the 4 Ohm MB Quart tower speakersx2 and 1 center 4 Ohm MB Quart on it.Ive also checked for possible short circuit and there was nothing. Infact it still switches itself off after diconnecting everything(speakers,TV,DVD etc.) from it. Any ideas?

The Yamaha HTR line, if I am correct, uses DACs and internal parts that are slightly less attuned to supporting multiple 4-ohm speakers. However, as I believe was stated in Audioholics' RX-2500 review, it was recommended that the user leave the receiver impedence setting at 8-ohms regardless of the speaker impedences.

Have you turned the volume all the way down since your brother caused this problem? How loud was he driving the speakers? Are you in a large, absorptive space?

Since your receiver will shut off periodically, however, regardless of connectivity, try checking the fuses or call Yamaha.

Check out the reviews on the RX-V line here at Audioholics, and see if they give you any help in regards to these settings.

Keep it unplugged for a couple of days, and, without having anything hooked up to it, plug it in and turn it on. I don't like to be the bearer of bad news, but if you have had it unplugged for a couple of days and then when you plug it in with nothing connected to it, and it still switches itself off after a few seconds, it is time to take it to a repair shop. But, by all means, contact Yamaha and see what they have to say. It is possible that your brother was listening to music very loud, and it overheated your receiver. Ideally, you would be using an amplifier that is designed for 4 ohm speakers when using 4 ohm speakers, but at the very least, you should have nothing on top of your receiver, with plenty of space all around it for it to be able to dissipate heat, and out of direct sunlight (those warnings in the front of the manual that many people wrongly ignore are there for a reason). If this is the result of overheating from your brother playing it loudly, and if you blocked the ventilation in any way, its overheating would be more your fault than his. Of course, it could also be that the unit failed without you or your brother doing anything wrong (beyond hooking up speakers with a lower impedance than Yamaha recommends), so do not assume that he did anything wrong; things sometimes fail due to manufacturing defect. And, if it is the result of it overheating, Yamaha would be perfectly right to refuse to repair it for free even if under warranty, because you have used it in a manner inconsistent with their warnings on the back of the receiver and in the manual.

thanks to you guyz. yes i left it off for a day without nothing connected and now it seems to work fine. nothing is on top of the receiver and there is good air circulation around it. for the future i will consider changing the 4 Ohms speakers, but when i bought this receiver i did contact yamaha and they confirmed that yamaha receivers work perfectly with 4 Ohm speakers, and that i only had to set the impendace to '6ohms'.

I'm glad it's working well now. Whether you need to replace the speakers (or add external amplifiers or replace the receiver) is difficult to say; after listening to your system for a while, you can place your hand on top of the receiver to feel how hot it is. It is likely to be fairly warm, but should not be overly hot. Unfortunately, it is difficult to say how hot is okay, as some equipment is designed with greater heat in mind than others, but if it is not very warm, you will probably be fine as things are. Anyway, it is good that you are keeping the vents clear, as heat is an enemy of your equipment (which is why they put vents on it in the first place).

Are you saying that now it works with the speakers connected? If so, something was changed when the speakers were reattached

may be i didnt give u all the details. i rechecked the speakers and in some cases removed the lugs where i felt the connection might not be perfect. but my interpretation of the problem was that the system shut off to protect itself. From what i dont know, poor connection, overheating, impendance i still dont know now.
About overheating, i know the amp gets too hot when you play the music very loud for a while and then shuts off, but it will still play if u switched it on and reduced the volume.

You should keep the volume down so that it never shuts itself off, as you are likely shortening the life of the unit by exposing it to excessive heat. You may wish to get a little fan to blow on it when it is running to help keep it cool. You could also buy a separate power amp for the speakers, and use the preamp outputs on the receiver to send the signal to the power amp. With what you are doing now, I would not expect your receiver to last very long.

I'd give some serious consideration to buying a two channel amp to power those front speakers. I think you've just proven that the Yamahas don't do well with 4 ohm speakers.

It appears that he is most likely exceeding the design limits when playing loud and 4 ohm speaker. At reduced levels, it should be fine. If he wants it loud, he needs an amp rated into 4 ohms.

Are you in some roundabout way saying I'm right? Where's my calender? I need to write this down.
Loud is relative. I run my 1500 at -10 at times. I attribute this to my large listening area. From what I've read here those levels, to most, would be excessively loud. For me it is not anywhere near an ear bleeding level.
Perhaps the same is true with dread. OK, maybe he just has neighbors that hate him, but anyway in his case it sounds like an amp may be the answer.
