    Same here. After 2.5 years of excellent use, I just had the Geek Squad out only to connect a new blue ray and new plasma screen TV. All the audio was previously done. There is no other component plugged into the powered/switched AC outlet in the back. Now, seemingly randomly, the amp will shut off, switch to STANDBY but the standby light will blink. I can use the remote to turn it back on, but it will only stay on about 1 - 3 min., then repeat same. It doesnt feel hot, and I've always run it with the cabinet doors open and vented. I'm not sure yet if it only happens using all 6 channels or volume sensitive, or both, or neither. I havent called the Geeks back yet.

From LANCE P: I fixed it. Be sure that all your speaker connections are perfect. No element frays that can arc, no +/- problems, no single barely connected wire. My problem was volume sensitve and I evidently had one + wire that was loose in the back. I corrected it and ran it all day with surround and good volume with no problems. So diligently check ALL YOUR SPEAKER CONNECTIONS, both in the back of the unit and at your speakers

Where is amp curcuit protection in onkyo sr


There are plenty of protect circuits in your receiver. Each chanel has one as well as dc protect and thermal protect etc etc. More than likely you have a blown channel that needs to be rebuilt.

Onkyo TX-SR 605 shuts of when i connect left front speaker


when i connect left front speaker it's shuts down .
That is probably due to protection caused by either
DC or over current. This means your troubleshooting is not complete.
Preform these steps.
Download SR605 service manual.
(a)unplug the amp.
(b)Connect left speaker (c)remove the vertically installed pre-amp board.
See this:
How to do?
1.Unplug the amp.
2.Remove the metal cover.
3.You will see a long vertically installed pre-amp board mounted next to those large power transistors fixed by 12 screws on a large aluminium heat sink.
4.Remove this long vertically installed board mounted by 2 screws.
5.With 2 screws removed, just pulling this board out and hold it with one hand.
(d)Plug the amp and switch it on.
(e)If your amp stays ON forever, the problem is from this long board.
(f)If switch off at once, the problem is from power amp board.
Try the above- mentioned steps to confirm DC or over-
current in left channel.
(g)For DC protection, replace ALL components on left channel of the vertical board.
(h)For over-curremt protection, replace ALL components on left channel.

Replacing ALL components on a faulty channel do not cost you too much.

Amp Protection Mode


no, your output transistors maybe 2 of them are gone or the small power supply that feeds the other circuitry has become defective.
