Annoying Onkyo 605 problem.

[X-Ninja]

Hey guys. I bought my Onkyo 605 almost a year ago, and ive dealt with this insanely annoying (what-appears-to-be) "overheating" issue the entire time. Basically, when i turn it up too loud (arount 70) and a bass-ey part kicks in, the receiver shuts itself off and flashes a red light at me.
If anybody knows how to fix this, or any ideas on stopping it from happening, it would be great if you could post them.

At first i thought it was the speaker wiring
- So i bought new speaker cable and re-hooked everything back up

Nothing.

Then i began to think it was my (slightly destroyed) HDMI cable
- So i bought a new one

Nothing.

And now im beginning to think it is because i don't have a sub-woofer. Which may or may not be the issue. ...but before i go shell out however much money it'll cost for a decent subwoofer, it would be nice to know if the problem will remain.

Anybody wanna buy an Onkyo 605!?
...payed 650.00 for this thing, and i got a deal for knowing a guy that works at the place where i got it. Gotta love Canada...

Anyway, Heres a video i made displaying the problem in real time (not that its hard to capture. It happens all the time).

What kind of speakers? Ohm rating?

Interesting approach - to make a video of the problem. I could barely make out your voice though.

Good question. I dont know. They're very old speakers. I need new everythings for my home theater... but maybe this'll help?

Technics BST200

Ha. Yep, sorry about that. I was trying to look at the screen while i was talking.

It might say the ohm rating on the speaker???

A 4 ohm load may drive your receiver to hard and cause it to shut down or go into protection mode from running to hot.

Found it! The sticker was ripped off on the speaker i was checking.

They are 8 ohm speakers. (the fronts)

My back speakers are 6 Ohm, 200 watts.

I dont have the 7.1 up anymore since i moved the receiver.

Ill try that tomorrow i guess. Thanks! I was hoping for an easy fix though...

WOW $650. I think i paid $525 for my onkyo 705 1.5 years ago. Anyways, I have read about the overheating problem on the AVS forums. I purchased an auxiliary fan to place on the rear right corner since that is where a majority of the heat is coming from. This is the BTX fan i bought since i am working with limited room. With your setup it might be better to go with something like this.

I checked out the AVS forum and the 605 thread didn't have a nice FAQ like the 705 thread does. Read up on this thread Onkyo TX-SR705. I know its the model above yours but most of the information is relative. When you go there hit "CRTL + F" and type in "temperature" and read about the way your receiver can display a temperature readout to see if its actually overheating.

Hope this helps. If i learn about anymore info I will let you know.

Edit: Check and see if any firmware updates are available.

Thanks for the links! Ill see if putting a fan near it helps, but i dont think this is an overheating issue since it happens even seconds after you turn the receiver on.

hmmm. Well thats just wonderful... So i guess ill call Onkyo tomorrow and see what they can do for me. Not sure how well this is going to go since i have no proof of when i purchased the thing. (It was a little after christmas).

Thanks for the help Jason and everybody else! Appreciate it...

Still, if anybody else has any ideas im here clicking reload every couple of minutes while i play PS3.

I would be very curious to know what would happen if you hooked up a powered sub. It WOULD take quite a bit of strain off the receiver. I have the same model and I've used a powered sub since day 1 and mine has never even gotten hot to the touch.

Also as far as a fan goes, I use one of these to help cool my PS3. It's a 4" desk fan that sits at the back corner of my PS3 blowing hot air out the back of my enclosed TV stand.



I just plug it in and leave it running all the time. It's very quiet, but made a huge difference for my PS3. I can only hear it when everything is off. Picked it up at Target for less than $5.

Good luck getting it figured out.

Hope the Onkyo people will help you body... If it's running that hot and you've got good clearance on every side then I would think there is something wrong with it. Running a fan will help but why is it running that hot in the first place!

Am I the only one thinking that even with the protection, the heat will potentially damage the receiver and cause it to fail before it's normal expected life?

I willing to put money on the fact that you probably had some wires touching and when you cranked it, the resistance got too high and the reciever went into protection mode. I've done this myself on my old reciever. When you moved it to the window where the fan was, you moved the wires and since they were no longer touching, you can now crank your reciever. There is nothing wrong with your unit. Stories like these are how overheating rumors are started

lol. Nope, no wires touching. And i didnt put the 605 in my window. I took a giant fan that normally sits in my window, and put it on top of the receiver.

Have you attempted to reset the amp to factory defaults!? Have you set it up properly with the MIC and what not?I do not mean to come across as a know it all but I just can't see how I have had mine up without any problems I mean worst ways I know Onkyo hands out a 3 year warranty so not too sad.

a 3 year warranty!? Thank you for saying that! Ill look into it more. I thought it would be a one year warranty meaning id have to send it in within the next few months - which would mean i wouldn't be able to play LittleBigPlanet. ...which is a giant issue for me.
3 years... Nice.

Haha. We appear to be different people.
