Question about Onkyo TX-SR803 Receiver

TX-SR803 with no sound or popping hissing on any input

I have no sound or a popping hissing sound coming out of the speakers. The problem appeared after a lightning strike hit a nearby pole and traveled in damaging other electronics.

My question is, it is worth fixing? When I removed the cover off the amp, there appears to be no damage to any of the 8 internal fuses (although I can't see through 2 of the fuses because they are not clear glass).

If this problem + lightning damage = known excessive repairs, I'd prefer to just forget it and buy a new amp. If I could expect $100-$150, then it becomes more of a realistic option.

Any thoughts would be appreciated!

    If the internal fuse was opened, then wouldn't all power stop to the receiver? Mine has a full digital display and runs as if ok...just no sound out of the amp itself. Is that right in your opinion on the internal fuse?

It is common for a short term power surge to open up the internal fuse in the main power transformer. Without testing some components inside the unit, I really can't say for sure whether or not the unit is worth repair. I would suggest that you invest in a detailed repair estimate at an authorized Onkyo service center.

Keep us posted.

    Nope. I mis-read your initial entry. If you are getting just a little noise like popping etc, then you have a digital processing problem. Depending upon the exact design, you MAY be able to get proper sound by dis-abling any surround processing. If not, then I would first look at the DSP board as the source of the problem. That board may exceed $200 though.

Onkyo TX-SR606 power on default input setting and hissing sound


I had the same problem for more than a year but just lived with it. The solution is to reset the receiver to factory defaults. Page 96 of the owners manual, "turn the unit on and while holding down the VCR/DVR button, press the ON/STANDBY button. CLEAT will appear on the display and the unit will turn off". Problem solved!

No audio on any channel, even in audio setup mode, no audio headp


If you have any of its sound outputs connected to a TV or tape deck do they get the signal? If so, then we know there is sound processing somewhere inside the unit but not emerging to anyplace that requires amplification.

A quick basic check would be to tune an FM station, run an RCA cable pair from the audio output for a tape deck (see the picture at the link) to an analog audio input on your TV. Select that input on the TV and you shouls hear the FM station, or anything the receiver is configured to play. If it's silent then there is no audio signal circulating in the receiver to get out to the amplifiers.

Check to make sure Multi-Channel input is not selected unless that is what you're listening to as it bypasses all other sources analog and digital EXCEPT the tape; and check any Mute or Zone Controls, too.

If you hear the program on the TV but not through any attached speakers, then the amplifiers are all disabled for some reason. The click I asked about before... when you turn it on does it get a click about 5 seconds later. That would be the protection circuitry turning OFF to allow the amplifiers to function.

I notice it has a Tape function. Make sure it isn't selected as it assumes a tape deck or processor is attached and will only play back what would be coming FROM the tape deck or processor. On my Pioneer receiver it also disables any digital signal processing.

Sometimes when I'm watching TV with the remote on the seat someone moves and something bad happens. It's always some unfamiliar button that gets touched unintentionally. Look over the remote for things like MUTE, Multi-CH, Tape.
