Question about Onkyo HT-S680 System

Onkyo receiver (HT-R430) cutting out after a few seconds

The receiver turns off about 3 seconds after turning it on. I hear 2 "clicks" (like relays) when I turn it on, and the display lights up, then a few seconds later 2 more clicks and the display goes blank - and the standby LED flashes (I think it is supposed to stay lit continuously).
This happens with or without speakers connected - but no sound is ever produced.
I removed the cover and checked fuses, and they were OK. I unplugged the 120V power wires to the transformer and tried it, and the unit will stay "on" - I hear the first 2 clicks - but obviously no display.
I read about 1.1ohms across the transformer primary - but I really need to verify that with another meter.

My hometheater onkyo ht-s 3500 problem increCVasing volume level 45 cut off amplifier

Hello KAMAL, This means that the unit is going into protect mode. This is typically caused by something internal or a speaker connection could be causing it. To isolate if it is a speaker or the receiver you would first have to turn it off and disconnect all of the speakers. Turn the unit back on and turn the volume up to 45 with no speakers connected. If the unit stays on then you will know that one of the speakers was causing this short to happen. If that is the case I would check all of your connections. If the unit turns off when the receiver has no speakers connected then it is an internal issue and it would have to go for service. Thanks, FJD

Onkyo HT-SR800 won't turn on

If you call Onkyo directly, 201-785-2600, there is a procedure to "reset" the system, something like holding the power button on and holding down another button for a few seconds. Can't remember which, so I can't be sure, but try giving them a call.

Yes, you can switch between Coax and Optical inputs, but not using the remote. Press the button "Input" on your HT-R430

HS-R430 System

Connect the audio cable (red & white) from DVD player to the Audio DVD in (L/R) of the receiver.
Change the source selector to DVD.

Incase of coaxial o/p from the player, connect it to the coaxial i/p of the receiver. Then select the digital i/p button twice located in the front of the receiver.

Should work, though. This will provide a power toggle function to the Power key.

Use red numbers for the red OK/Select button remote, grey numbers for grey button remtoes.
Temporarily assign setup code 30842 or 0842 to AUX
1) Tap AUX
2) Press Setup until 2 blinks
3) Enter 30842 or 0842The remote should blink twice

Assign NEC1 IR protocol device 210, subdevice 108, function number 203 to Power (you don't need to understand these numbers)
1) Press Setup until 2 blinks
2) Enter 994 (2 blinks)
3) Tap Setup
4) Enter 00051
5) Tap Power (not All On)
The remote should blink twice

Assign setup code 30135 or 0135 to AUX (this is NEC1, 210.109)
1) Tap AUX
2) Press Setup until 2 blinks
3) Enter 30135 or 0135
The remote should blink twice

Surround sound

It must be about the sound quality need of your amplifier. The sound processor simply needs to get clear signals from sources such as fm/am receiver, dvd/cd players etc. in order to manage'em to give you the optimum surround sound. If the fm receiver has an "FM MUTE" option, I recommend that you turn it on. By doing so, you'll receive only good quality fm stations, furthermore your amplifier will let you get surround sound. The second issue you mentioned has its own answer inside. Use a "new" cd player, you can get optical cables, digital coax cables to improve the performance if you like..
