I had the same problem with my TX-SR601 receiver.
Solution: I changed the capacitor C766 (100uF/6,3V) on the "DSP and main microprocessor" or "U1" board. This capacitor is responsible to keep the settings in the memory. It is directly next to the SRAM ICs (Q705-706) (type: CY7C1019BV/CV33-15VCT).
Now the receiver works properly again.

    Sorry... The success is not complete :-( The memory works only 1-2 hours without power (before the action it immediately forgot the settings). Still trying...

    Hello. A year ago I took my sr601 to a service. The 2 SRAMs was changed and since then it works properly!

SOURCE: My Onkyo Receiver TX 601 is turning itself off

Adjust bass control to half position then feed loud signal,if it shut off adjust the bass contol to zero position,if it shut off again the defect is in the over load protection circuit it is already sensetive to loud signal.you may call the nearest audio amplifier technician on you.

Hope it may help you,

SOURCE: Can I play my ipod through my Onkyo TX-SR600 receiver?

All you have to do is get a 3.5mm plug to two RCA plugs lead and plug the 3.5 Jack in the headphone socket of your ipod and the two RCA's into an aux imput and away you go. If you get one of the small docks, that will stop the battery running down, but you don't need one.
By the look of the picture on FixYa it looks the RCA's can go in the front socket under the volume control.

Testimonial: "Thanks so much. Great solution."

SOURCE: I turn my Onkyo TX-SR600 receiver on. After a few

The most common problem found on FixYa for Audio Video2_bing.gif Receiver's is:

My receiver say's "Protect" or turns on then off. What's wrong? Seven times out of ten it is a shorted speaker or speaker wire2_bing.gif. To determine your exact problem, the first step is to disconnect all speaker wires "at your receiver" Next: Turn the receiver back on. If your receiver still says "protect" or turns off, it needs to be serviced. If your receiver stays on; reconnect your speakers one at a time and power back up after each speaker. You may find that after reconnecting all speaker wires it works! Most commonly the small braids of wire from the + to the - have touched and have caused the problem. In some instances, you noticed the problem only when turning the volume up. either way, make sure the exposed wires to your receiver are no longer than 1/2" long and are completely under the screw down terminal or slide in. When you've found the wire or speaker with the problem, your receiver will go back into "protect" At this point, disconnect the wire from the speaker at the speaker that may be causing the problem then test again.* Note* Make sure speaker wires do Not touch each other as this Will cause a short! If you turn the receiver back on and it stays on, you now know the problem is in your speaker itself. To test your speaker, you will need a multimeter. Set it to ohms resistance and touch the speaker terminals, if there is a short internally the meter will read "1......" If it's an analog meter, it will peg to the right. There's your problem. Now, within any speaker there are quite a few possibilities as to what could be causing the problem. Most common is a blown coil and the speaker needs to be replaced. Some speakers have internal crossovers (usually floor standing speakers2_bing.gif) and may have a shorted or burnt board (usually very visible brown burn marks on the board) and can possibly be repaired if your handy with a soldering iron. Now, if you disconnect the speaker wire at the speaker and it still says "protect" Check your wire for the obvious cut or nail thru the wire if possible. If your system has wiring that runs behind walls, you may need to use your meter again. Disconnect the wire at both ends, keep the ends separated, put your meter on ohms resistance and touch probes to the + and - wires at one side. If the meter pegs to the right or reads "1...." the wire is shorted and needs to be replaced or repaired at the short. Hope this helps.

SOURCE: Onkyo TX-DS777 does not retain settings after power loss

No internal battery, a large "SuperCap" on the main board acts as one. Look for C8007, 0.1 F, 5.5V.

My onkyo TX-sr600 will not power up. "Standby" LED remains lit while depressing and releasing power button.

Hello
When the device stay on STBY it means it is in a protection mode.
means also safe mode so it wont make more damage.
Try this my friend.
1: please check speakers cables.
If you have some knowledge in Electronics
test on the supply board in/out volts and power Amp voltage (Not on the transformer)
check with diagram as shown

My Onkyo TX-SR600 shuts off after a few seconds when I turn it on

Hello, I am sorry about your issue. I suggest disconnecting all of the speakers from the receiver and unplugging it for at least one hour. Plug back in and turn on. If it does not stay on it would need to be serviced or traded in. It it stays on turn off and add one speaker and turn on. Follow this process until all speakers are connected. If you are interested in a trade in please contact us at 800-229-1687 option #3. Thank you, Onkyo USA
