    Dan thanks, I kept trying different confurations until I realized that it was fine as long as the center channel wasn't used. I have an old bose speaker setup and the fronts run through the sub. I checked what I could (not much in there) and it looks like a cap was bad so I ordered a few I'll let you know how it turns out Thanks for getting back to me

    Hi Abrsvcs, Dan Hi speakers are back on track or fixed... So you mentioned regulators on the surround board, ahh, sound board there are 6 boards total hdmi, a video, a side board that apears to tie those 2 to the main, another with board with six(? ) with heat sinks and then the last board has the outputs to speakers and stacks directly over one cornerof the main.

    Some stuff goes through this (speaker board) to the main. Is this the sound board or is this just the speakers and the main has this separate area and this is the sound board? Last thing directly below the speaker board on the main what appears to be some audio there are 2 fuses, every where else on the board appears to be protected by breakers. Well anyway the regulators look like what?

    Thanks Dan

Sorry about the delay, I did not see this posting.

The other speaker configs utilize the surround processing section. In stereo, the surround processor is bypassed. Based upon your brief description, I would think that the surround processing section is producing DC voltage which is detected by the output section forcing the unit into protect mode. This is not a problem that is easily diagnosed remotely. One thing to chech, if you can, is the power regulators on the surround board. Make sure that the solder connections are good. If they are OK, then I would suggest that you get a detailed estimate from a local service shop. Report the results here and we'll work through the actual repair.

Onkyo tx ds 575 shuts down

What preceded the problem starting? Was it spontaneous or human caused?

The age of the wires is less relevant than A) they're connected correctly; B) they're not shorting to anything.

You need to isolate the cause.

Disconnect all speakers and attach just one. Try it somewhere. If it works, use it to test all other speaker connections. Do they all work? No = isolate.

Yes - Add a second speaker to pair A or B. Still working? Move them to the other pair. Still working? Try the second set of speakers.

Not working? Isolate.

Onkyo digital reciever has poping noise when in dolby sound

I have the same reciever, and had the same problem.  Contact Onkyo, this is a known issue where defective DSP chips were used and manifest problems with a popping / clicking sound when using surround settings.  These receivers also have a Dolby Digital input issue that can cause audio dropouts when watching cable or SAT broadcasts that encode DD using a 'newer' broadcast encoding methods.  Onkyo is covering the cost of that repair for me now, even though the receiver is 5 years old now....

Onkyo TX-DS575 turns off after about 10 min.

it could be a failing speaker causing the fault. Disconnect one speaker and run it to see if the problem persists and repeat with a different speaker until all speakers have been disconnected and the unit run to failure. If it stays ok, with a particular spkr off, it's the speaker. If it shuts down no matter which ones disconnected, it's probably a crack on the PCB which expands as it heats and causes shutdown.

Onkyo TX-DS474 Receiver shuts down after Standby mode.

It's going into a protect mode. The amp is probably shorted out. Disconnect the spkrs and turn it on. If it still shuts off, it's the amp, if not, it's the spkrs.
