Its an onkyo av reciever tx-sr601It was gaven to me from a friend...I can turn it on but it shuts off seconds after. I have left it unplugged many times and have retried but the same problem occurs. Does it have a password or is it fried?

Resetting the AV receiver to its factory defaults To reset the AV receiver to its factory defaults, turn it on and, while holding down the [VIDEO 1] button, press the [STANDBY/ON] button. "CLEAR" will appear on the display and the AV receiver will enter Standby mode

Have you provided adequate ventilation?
May be your receiver is running hot and when there is loud volume it is obviously getting overloaded. There are no fans inside 674, the only way to provide good ventilation is to keep the top of receiver clear for atleast 6 to 8 inches.

Hope that helps.....

Wouldn't any device that required a password presuppose it come up far enough to communicate with?

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Do you mean ONKYO TX-DS484?

Read the manual which is available for free download after you register at retrevo.com.

Yes it is. The easiest way to go about this is to get a stereo mini male to left and right male rca cable. Connect the stereo mini end into your ipod, and the left and right male RCA end into an available input on your reciever. Change the input on the reciever to correspond with the input you connected to. Ensure your ipod is powered on and playing with the volume turned up. This set up will play through your reciever but will not charge your ipod. If you want it to charge while playing, than you will need to get a dock.

The manual suggests disconnecting inputs and outputs and power, letting it sit for an hour, then plugging it back in and turning volume to max to see if it still shuts off. If it does, the problem is with the unit. If it doesn't, the problem is elsewhere.

Judging from some other sites, this is a common problem. If you take it to a dealer, suggest they check the AC input. Before anything else, make sure that there are no stray wires on your speakers connecting the positive and negative clips, which will cause a short and activate the amp protection.

I had the same problem with an Onky502 and replaced it today with an Onkyo606. It worked fine for an hour then started shutting off automatically. I'm following the manual and letting it cool off now for an hour, and meantime I'll check my speakers.

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.

don't run you video from the projector to the reciever. just run it to the dvd and run the sound from the dvd through the reciever

i have the same problem with a onkyo tx ds494

The only remote that will definitely turn the sat subtitles on/off is the sat remote. The other subtitle buttons on the other remotes refer to the DVD subtitles and the subtitles generated by the tuner in the tv. The subtitle option is greyed out on the tv because you are not on the tv tuner.
