Onkyo TX-SR803 Receiver - Answered Questions & Fixed issues

The speaker impedance is not the problem.

Sound like a semi-component is faulty within the unit you need to get it serviced. Does it indicate any thing on the LCD when powering up before it dies ?

Get a separate amp for the 901's and the rest falls into place.

1,2, 5) Place the 901 Active EQ between the pre/main front OUT of the receiver and the TFM-55X. Attach the 901's. Keep track of the jumpers you remove from the receiver. Or replace the jumpers with RCA splitter cables so you still have pre/main connection but can share the output with the TFM.

3) Pinnacle subwoofer (self-powered?) to the subwoofer out of the receiver.

4) Bose (AMS???) 5. As surrounds on the receiver. Place the sub module toward the rear so it mates sonically and directionally with them.

What? No center speaker? I'd get something more robust with bass capabilities, like a pair Bose 301 series 1's because the tweeters face in one direction only.

Except for the amps and the cube stuff that is essentially what I have. 6.1 with full-range speakers everywhere.

So, it has NEVER worked? Review your connections regarding the speakers.

Generally speaking, an amp protects 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. Eure 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.

Use Deoxit on the switch. It is a contact cleaner available at Radio Shack and Fry's. Exercise the knob well. It worked for me on my newly acquired Onkyo A809.

call the onkyo to help with that !

The remote sensor is part# 241341 or 241335. On the front board its marked U7501.Some times initializing the unit will restore normal operation. Althougth afterwards you will have to re prgramm all your settings and presets. While on hold down the VIDEO 1 button while pressing the power button. The display will read "CLEAR".

Connect HDMI cable from the rear panel of the blu ray player to the DVD/IN digital section, labeled as "HDMI/IN" on the rear panel of the receiver.

most likley switch is weak,[dealer repair]

same with me nerd

This receiver does not support DTS HD Master audio and/or Dolby TrueHD
which is true blu ray audio.But it will allow the full HD quality of 1080p video to pass through to your tv...meaning if your TV is capable of FULL HD(1080P) then you will get bluray video but audio will only be Dolby digital.That is still really good and the difference will be felt only if you have a dedicated Home therater system with 5 or 7 channels of speakers in your room and separate subwoofer.

Anyways this is a good network receiver and you should be enjoying a lot of internet radio.

Actually it looks like a small palstic disc so you might jsut get it so look for it. You should get one of those radioshack cheap mics with low impedance if you do not get it.

something is wrong either in one of your speaker connections or in the unit itself unplug for awhile to reset.try it again.make sure all connections are correct and nothing is touching.if that does not work it will be the unit itself

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.

for verizon cable box to system

Onkyo receivers have a safety circuit in them to protect the Amplifier from blowing up:

If you listen closely when it shuts down ( after a loud scene ) there is likely a loud 'Relay Click'..
If this is what is happening you might be able to verify it by turning the volume all the way 'off' and waiting for the circuit ro reset ( releasing the safety relays & returning power to the internal Amplifier ) : you should hear another click, yhen you can bring the volume back up carefully and there will be sound again.

This safety circuit trips when then Onkyo receiver detects an 'Over Current' condition on the
' Power Supply ' that feeds the internal 'Audio Amplifier'..

Generally caused by:

1.
Improper load presented to the Amp outputs ( FL, LR, RL, RR, SUB, CENTER )
If you can ( one at a time ) turn off the SUB, Center, Fronts and Rears: trying to re-create the failure each time while you have one part of your system disabled or having their level turned way down..
You can isolate where the problem is coming from.

- any or all of these speakers being the wrong Impedence ( I.E. 4 Ohms instead of 8 Ohms )
Unless the receiver manual or the sticker near the 'speaker connetor' specifies a range or another value, you should assume 8 Ohms. Your speakers should say on the back of them.

- any of the speakers being connected in parallel ( 2 speakers to a single one speaker output ) .. Two 8 Ohm speakers connected in parallel make a 4 Ohm load to the amplifier.

- If the Suwoofer is Passive ( Not having its own power cord and amplifer ) it has a
Passive Crossover : this crossover can have its own power rating or limitation.. If it is constructed with capacitors that have too low of a working voltage, then they can saturate and the crossover itself can present a load to the amplifier that will case this 'Over Current Shut-Down'..


You user manual should detail this.

Did the speaker cailibration work on the speakers in question?
If YES, then the program material or settings you're using don't require the rear speakers.

By "Back" do we mean Surround or Surround Back? Surround Back speakers are the 6th and 7th channels in the 7.1 matrix. Not all source material has programming for them. But when using any 7.1 digital surround mode you can get anything, even stereo recordings, to output something from every speaker.

If NO, check your connections...

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.

Plug it into the cd input, with the two rca cables. We've had this set up for years. No longer use a cd player at all.
