Help me help my neighbor

[JimShaw]

He has a 5.1 system using Onkyo TX SR605 receiver, Panasonic DMP BD85 player hooked up to Polk RM101 speakers and a Polk sub.

The problem: In the past my neighbor (every once in awhile) would hear a loud pop in his speakers and the surround sound would turn off leaving only the TV speakers able to work. In a short time, the surrounds would turn back on.

A couple days ago, the loud pop was heard again, the surround speakers turned off and now they no longer turn back on.

I was called over and I checked out everything that I could: wire connections, etc., etc. Everything is OK except no surround sound.

My thinking is the Onkyo's circuit breaker has been tripping and now gone bad?????

Is this a possibility or is there something else we might try???

It's not the Onkyo DTS bomb problem, is it?

That was my initial thought as well.

Regarding the "Bomb"

I read the thread and it seems the 605 may not have the problem???????

A quote from that thread.....
it seems that the 605 is not included. the zip file indicates 705,805,875,905,885

[JimShaw]

Anyone have a thought?

By the description, it sounds to me like an issue in the Onkyo. Try some of the different sound options and see if the problem replicates itself. Make some notes so that when you take it to a service depot - if you decide to do so, you can have a very accurate description. It'll help the technician. This is not a speaker problem IMO or wire issue. It really sounds like bad circuitry in the receiver. Is there a reset button, or can you try unplugging it for awhile to see if it resets after plugging back in?

I can tell you for sure it's not the bomb. I have that problem and it would be a very loud POP, but it did not turn off any speakers. The firmware for the bomb is as you said 705 and up.

[JimShaw]

The cable TV and Blu player can be played through the TV speakers but nothing works through the receiver to the surround speakers.

To me, something is wrong with the receiver.

I wasn't aware of this. Good to know.

As for the issue at hand. Outside of resetting the receiver, unplugging everything from the 605, and trying a new player/input I'm about out of ideas.

Has the neighbor had the 605 for awhile and the problems are a more recent thing? Perhaps there is a bad ground or the outlet is bad.

At this point the receiver may need to be sent in for service to be fixed, but according to this thread the 605 also had the problem. Apparently, the 605 has a unique file whereas the one you mentioned is for all other models. The DSP update is also different from a firmware update.

The 605 file is no longer available from this specific post. Also take a look at the DSP file attachment at the bottom of the first post.

You can find to 605 DSP update via a link found in the signature block of Tspeer's post in this thread:

http://www.avsforum.com/avs-vb/showt...6#post18861246

I downloaded the file and it does contain the 605 DSP file. Beware that this is a large download since it includes many other files for all of the x05 series.

Also, I noticed it includes a Service Bulletin file, SB 07008-R1, which states:

Symptom:
During playback in any listening modes except Analog Direct, Multi-ch, and 2ch Pure Audio, Pop noise randomly comes out from all channels when the internal temperature is high. This noise stops when the unit inside is cool down.

The solution for that problem is to replace a specific capacitor on the board.

Also, I was looking at the 605 manual and noticed several things. First, check the impedance of the speakers being used by your neighbor. (EDIT: nevermind this suggestion; based on your first post, the RM101 are 8 Ohms) The manaul has the following precaution:

Speaker Connection Precautions
Read the following before connecting your speakers:

North American models:
Only connect speakers with an impedance of 6 ohms or higher. If you use speakers with a lower impedance, and use the amplifier at high volume levels for a long period of time, the built-in protection circuit may be activated.

Second, you can try resetting the receiver via the folowing option:

If you can’t resolve the issue yourself, try resetting the AV receiver/AV amplifier before contacting your Onkyo dealer.
To reset the AV receiver/AV amplifier to its factory defaults, turn it on and, while holding down the [VCR/DVR] button, press the [STANDBY/ON] button. “Clear” will appear on the display and the AV.
