Question about Onkyo TX-DS797 Receiver
Did you eer encountered a problem wherein no sound/audio is heared on both analog and digital domain even I switch from one sourcechannel to another. I can see a display wherein the reciver detects a signal i.e. pcm or dolby but does not enclosed in a red box display. Intermittent sometimes it will produce sound and afterwards it will not.
Any ideas. Technical service Bulletin from onkyo?... thanks
I just read over the problem you were having with your Onkyo TX-SR500 receiver. It sound like the unit needs to be setup for all five channels.Sence your symptom says the diplay shows Dolby D3/2.1. According to the owners manual with the remote control look for speaker setup whin the button is pressed the current speaker setup will be shown in the display. Press the preset/adjustment<> to change the current setting to five speakers. the listening mode will automatically change according to the number of channels you selected. Hope this helps. Radiotech

Hey, you have to set up the SOURCE to use bitstream instead of PCM. For instance, in my case, I had to configure my DVD player to output audio in bitstream. Then the receiver was perfectly happy, decoding Dolby D as it should.

Unfortunately only the higher end Onkyo Reciever pass audio over HDMI for sound. 605,705,805,905 exc. Your reciever will carry Video over HDMI but you will need a digital optical cable for sound.

regulated voltage to the processor circuit like drop in these onkyo after 8 years. This or a small capacitor fails in this voltage line.

SOURCE: hello. I have some problems 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.
Check for loose speaker connections at the speaker as another possible root cause for intermittent shutdown.
