Onkyo TX-SR507 shuts off and on Is anyone else having this problem? I tried everything from proper ventilation, better speaker wires, checking connections, even unplugging unit and removing speaker and component wires for an hour, which worked for 2 days then the issue is back again. I don't have the volume loud and it would shut off and on by itself - gets annoying. I know its protection mode, but something is causing it and I dont see any problems from my end. Anyone?

Same issue here. I already sent one back to Onkyo for replacement, and the replacement does the same thing.

I have the same problem. It seemed OK until I added a BluRay DVD and then even with the window (winter) open behind it shuts down with the volume setting much about 30. It runs somewhat hot, but I don't think it should be hot enough to shut down. Currently I must use the TV volume set higher and hard to get good sound from my high efficiency regular speakers. With the tuner I have no problems. I am not happy with the unit.

I didn't have any issue with the power, though I used a power condition unit to regulate the incoming AC power to provide constant good power in. I would hear some clicking sound from time to time, but the receiver working just fine. Hope this will help.

Are you sure it isn't the subwoofer? It stays on all the time even when the system is turned off and produces a low level hum, constantly. That seems to be the norm for all the subs and the Onkyo receivers. I was surprised to walk into my media room and hear the hum coming from the sub and the system was turned off. Sub is always in stand by. Just a thought.

I have two of these speakers. The first one I bought stays on all the time. The second one turns itself off after awhile. No idea why.

Hi, Onkyo support had us use 1141-0108-0400 firmware. It still produced interrupted video signal. We went as far as to have a service tech check the receiver. Unfortunately our long relationship with Onkyo has now ended and we have purchased a Denon unit that is lovely. Good luck to you.

Mine failed in February right after the warranty expired. Onkyo fixed it out-of-warranty and - alas - it failed right after the six month warranty on the out-of-warranty repair expired. I'm looking for something else.

If it's what happened to me... Everything cuts out... then the message on the unit says "Protection Mode" (or something to that effect) If so, it was after I pushed the unit too far back in the cabinet and accidentally broke the solder point on one of the speaker terminals. These connections are apparently quite fragile and it doesn't take much force to break it... causing the amp to sense a "short" in the system. This then puts it into the Protection mode. I tried opening it up to re-solder, but the PC board was slightly cracked- no dice. Threw it out and got another one... otherwise, they work great.

I agree that no one should buy this unit at this point in time knowing what's going on with it. HOWEVER, for those of you who have, remember you have a 2 YR warranty. Mine went out at 15 months and I was able to take it to a local authorized Onkyo service center and have it repaired for free. Runs like new now.

I had the same problem a few months back. It is a safety feature that stops the system from overloading. I noticed at the back where i had connected my speakers there was quite a bit of copper wire showing and again on some of the speakers. I cut them down so there was just enough wire for connection to the back of the receiver and to my speakers. Since then it has not switched itself off once.

I personally think its a defect. Had the same issue without any storm. Denon has a two-year warranty on those though so they repaired mine for free, minus the $60!!! It cost me to ship it to their repair center.

I would suggest checking with Onkyo Tech Support. Hope that helps! Good luck!

You know, I never thought about checking it. All I can say is I have one serving each of our computers and they work perfectly. Thinking of replacing the regular APC on the TV. But I'm not sure it will shut off my subwoofer when the tv is turned off because the tv still draws an amp or two when it's off. Maybe I'll try one of the 'master control" surge arresters to see if will shut off the subwoofer, before I get another one. Anyway, when you turn on or off the computer, the monitor and speakers come on or off with it. Nice.

I too had a TX-NR515 delivered last week from Amazon with this firmware version. It would not allow me to put the other version of the firmware on it via USB as it said it was up to date. I called Onkyo and they said that as long as the last 4 digits were 0400, than it is the most recent update, even if there is some difference with a 5 instead of4 in the first sequence of numbers. So far it has been working just fine... but agian, it has only been a week or so.

I also have a problem with Speakers shutting off often, and I have them plugged in, not on batteries. When they work, it is great. Wondering if it would help if I got a larger transmitter.

I had the same issue, and the problem was the HD board failed. After doing some research , I called Onkyo and they paid for the out of warranty fix because it's a known issue.Don't know whether or not your problem & solution is the same, but hope this helps.

This is going to sound weird. I had the same problem. I called Denon. They said vacuum the headphone jack. I did it, it worked. Weird, I know. The woman on the phone said dust shorts the headphone jack and causes the speakers to shut off.

I can't say anything specific about that problem what I can tell you is that these were a known faulty product from onkyo. It was the first and last onkyo receiver I bought. My receiver went bad after a little over a year of use. Went back to Sony and it's all I buy.

Try disconnecting all speakers, turn it on & run it at 70% volume for 5-10 minutes. If it still goes into protection then you know it's a problem with the unit and not your speakers/wiring. If it runs fine then you know there's a problem with your speakers/wiring. If the unit goes into protection mode then perform a reset:With the unit off, press and hold "Game & A-DSX" and turn the unit on. The display will start blinking, after the 5th blink release the Game & A-DSX Buttons and the system will go through the reset procedure.
