Question about Onkyo HT-S680 System

1 Answer

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.

    I bought a HT-S680 system and it worked fine for the first 10 days. Then the receiver started to switch off automatically after turning it on - within 2 or 3 seconds. When I tried for the third time I saw smoke come out from the side. I have given it to an Onkyo service center and they have promised to replace the circuitry if required. But, I am still doubtful if I will not get this problem again.

Onkyo HT-RC360 The receiver has a clicking sound when powered on. then turns off

No! I'am afraid not, if you have checked your wires carefully and it checked, the audio output semiconductors will require a technician to remedy the problem.

I have an ONKYO HT-S3305 which transiently 'cuts-out' the sound - lasting only seconds (hooked up to TV/satellite HD receiver) Seems to start after about 1-2 hours after switching on. Not the signal...

It sounds to me that some part of the circuit possibly an IC is overheating after several hours and develops a fault.
This will be a very tricky thing to track down. So maybe best to take it to an authorised service agent.

Power on but no tuning or sound from other sources

Check for "Tape Monitor On" button. According to Onkyo's web page "Press and hold the tape button for two seconds allows the tape and MD sources to be switched - Also try the speaker A/B switch. - Check back for further assistance - The web page for your operations manual can be found at...
Then select your model.
Hope this helps

Onkyo receiver with no sound

There should be 3 clicking sounds coming from the amp. You amp miss the last clicking sound coming from the speakers ,spk, output terminals. There should be 3 relays on the spk output board. Their 12 contact points may have a layer of black colour oxide. Remove the oxide can fix the problem, perhaps.
1. Unplug the amp.
2. Open the cover
3. At the spk terminal, there is a horizontal board.
4. Look for the 3 relays and take them out.
5. Open the relays and remove the oxide layer by a sandpaper.
6. You need an iron solder, a desoldering pump and solder.
7. If does not help, check for the 24V for the 5 relays. 2 is for B+ and B-.
