My Onkyo TX-SR605 is a 5-year old 7.1 receiver. Two of the front speaker terminals just ceased to operate. This receiver model has been discontined by Onkyo, hence my difficulty in finding an original (any suitable alternate would also be OK) replacement for the speakers power board. Please advise on the part identification (make, model, number) and the best procedure for purchasing and having it delivered to a US address.
SOURCE: no surround sound
So your saying that you have no rear channel. Some recivers use a single stereo output ic for both sides on the rear speakers. you could have a defect with this IC . Anther thing Im sure you check3ed the obvious ie : the switch is on suround sound? If there is a front to rear fader is it in the middle? Good Luck
SOURCE: Powered Or Unpowered Subwoofers For Onkyo TX-8511
Greg- Powered subs are better than non-powered subs (also known as passive subs), anyway I see the TX-8511 has no sub pre-out on the back panel, so you need to decide what sub you will use and run from the receivers left and right speakers output into a subwoofers speaker in from speakers then back out to speakers, look at the back of a subwoofer and you will see like 4 sets of speaker hookups 2 in and 2 out, what this does is takes the low end or bass and drops the signal to the subwoofer then takes the mids and highs out to your left and right speakers, unless your regular left and right stereo speakers have large woofers a sub is the way to go.
SOURCE: Onkyo TX-SR706; Turntable output only from one speaker
Try some troubleshooting to check whether its the turntable or the the receiver.
What happens if you exchange the output cables of the turntable from left to right. Does the problem shift?
Does the sound changes from left to right speaker?
Similarly try on the inputs of the Receiver.. does the problem shift...?
This way you will be able to isolate the problem, whether with the receiver or the turntable....
Let me know, we can trouble shoot it further....
SOURCE: I HAVE AN ONKYO TX
The symptom you described can be caused by any number of things. I always start with the output power transistors which are the first things to blow with a speaker output overload condition. Unplug the power cord to your unit, remove the top cover and use an ohmmeter to check resistance from C to E on all 10 of the power transistors (Q6050 thru 54 and Q6060 thru 64) attached to the large heat sink. Blown transistors typically read <1 ohm, compared to good transistors that are >10k ohms. If you find a bad transistor it will need to be replaced.

Recommend changing your FINAL drive AMP IC most house BOTH right and left channels, your drivers right channel input is good cuz it is used to make the left channel signal
