Help!! I'm having issues with my Onkyo reciever..

[Steelmaker]

For some reason my receiver has started randomly powering off on it's own while watching tv. It doesn't seem to matter whether I'm watching a blu ray or if I'm watching regular television. I'll be sitting there and suddenly it just cuts off. I can power it right back on and sometimes it will do fine, other times it cuts back off in another minute or two. Anyone know what's going on with my receiver?!?

What Model Reciever? It sounds like it might be cutting off due to heat buildup, Do you have the receiver out in the open with proper ventilation? Anything atop the receiver?

thats about the same thing I was thinking. I have an onkyo receiver as well it's out in the open pretty much and have never had that issue at all.

It's a 606. It's inside an entertainment center with one of those cabinet doors with the dark fabric on the front. I bought it this time last year and up 'til now it has not been an issue.

I just re-ran the self calibration feature with the microphone. I don't know if this will help but I figured it certainly can't hurt.

I had that problem with mine a good while back. I suspect that it was a wire touching another causing it to short and enable the protection. When I rewired everything for a speaker upgrade I never experienced a problem like that again. Check your wire connections in the back to make sure no wires are touching. Also examine your wires to make sure there are cuts exposing any bare wire.

aside from heat issues, what may cause this to occur is also the speaker impendance. it might be too low for your AVR to handle. in general a good AVR can handle speakers rated from 6-8ohms. if using HTIB speakers, some of them are rated at a lower impendance, somewhat from 4-2 ohms.

i second that as well in regards to the wiring, please kindly check if any strays are out there too.

it would also help if you listed all other equipment connected to the receiver to include speakers and their ohm ratings. this type of info should always be given when asking for help so that we don't have to ask for it and can get right down to trying to help.

I really think that if this were the issue, it would've presented itself a long time ago, not one year after I installed everything.

My speakers and sub woofer are Polk Audio. I honestly do not know the ohm ratings. Sorry but I bought it as a set. All 6 components are Polk Audio brand. I cannot remember the model number of the set that I bought.

Most Polk speakers that I know of are 8ohm so that's not the problem since your receiver is rated for 6ohm and 8ohm speakers. I really think that there is a wire touching another wire or grounding out somewhere. That would be the first thing I'd look for since I'm sure it would trigger the receiver's built-in protection.

Heat shouldn't be an issue unless you have poor ventilation. My 605 never runs hot at all and I've run it for hours on end blasting music. The notion that Onkyo receivers run too hot is mostly unfounded in my opinion and I've owned two different Onkyo receivers. So long as there is ample breathing room for air to circulate that should almost never be a problem.

lets start by eliminating the chances that we have a stray wire that mightve got loose after time.

then we can work on the other possibilities.

Can the OP send a picture of the receiver and cabinet, maybe we can start with that. Particularly since it is possibly behind a door with black mesh?

Update: Ok, here's something I have discovered after messing around with it last night. If I keep the volume level below 40, it stays on no problem. If I crank the volume level above 40, it cuts off and the red "stand by" light blinks. WIERD!!

Overheating

I agree, sounds like an overheating fault protection mode especially since you mentioned the red light flashing. I suspect if you give it better ventilation, it will do fine. I have an Onkyo 805 and i know for a fact that if i had that thing closed up in anyway in it would go out on overheat. they do (like a lot of receivers) run hot, sometimes excessively. this place looks like it makes some pretty nice cooling equipment for things. take a look at the two kits listed last on the page. if you have an outlet in the back of your receiver you can plug it into there and it will turn on and off with your receiver. or you can get an optional thermostat controlled unit that turns on and off relative to heat.

best of luck if it's this or something else, hope you get it resolved.
keep us posted.

My only question is, why is it doing this now? I've had this unit for over a year. I have played plenty of movies at volumes higher than 40 and it has never been a problem.

[solarrdadd]

the only thing we can do is help do off-site "what if's" with your help. truth is we don't know what's going on, but based on what it sounds like...
having a piece of equipment for a year, a month 5 years, just like people it was working fine yesterday then they have a heart attack and die and we just don't know why. since this is happening on a regular basis, if your unit is still under warrenty, perhaps you should have it checked out and possibly repaired while it is (if it is) still under said warrenty. everyday you use it without knowing what the actual problem is brings you closer to full failure.

i do have one question for you, after leaving it off all night (it's nice and cool) if you turn your gear on, turn on tv and turn it over 40 does it go off right away or does this happen only after extended use, say 1 - 2 hrs or more? if it happens after turning it on from a full nights rest then you have another problem. if it happens after it's been running for a couple of hours then i'd feel safer saying it's a heating issue.

another thing would be to disconnect all of your speakers and turn it up to the volume you say it fails on and see what happens.

if it turns out it's a heating issue, then perhaps moving the receiver out of the cabinet you have it in now and letting it get full air circulation will help or putting the cooling system I agave you a link to would probably (maybe) help it.

hope this helps, keep us posted.

It happens after it's been running. For example, this morning I put on Wall-E and cranked it. It played through the whole movie no problem! After that I put in I am Legend, started playing and about 10 minutes in the receiver clicked off. I turned the receiver back on, took the volume down to about 32, and it played through the rest of the movie without a hitch.

Hey Steelmaker, I have exactly the same problem with my Onkyo 705. I read your posts and can tell you that I understand you perfectly. I think this is a manufacture problem. I began disconnecting all the speakers and all A/V connections and placing the receiver in a ventilated area.Turn on the receiver and turn up the volume at max volume (remember without connections) like the manual explain in trouble section. But after some on and off testings (during some hours) the unit burns. I can see the smoke and believe me, is very frustrating. Tomorrow I will bring the unit to an authorized repair dealer due to warranty date. Good luck with your baby...tell me if something happens.

Onkyo 606 = Garbage !!

Read about it all over the net. It has about 8 month to 1 year shelf life.
Just replaced mine this week with a Pioneer Elite VSX-23. Seriously Im sorry
but We own a defective receiver, and I beleive there is an action class lawsuit
in the works regarding Onkyo and that particular model.

sounds like a speaker wire issue.

Re-wire your setup on both receiver and speaker ends.
