Onkyo TX-SR674- no sound

I'm watching a friend's house while they are away and I accidentally hit something on the receiver I guess and now there is no sound!! They have an HDMI tv, DVD player, IO cable box, and Nintendo Wii connected to the receiver. The only time I hear any sound is when zone 2 is set to video 2 (the Wii) and even then the sound isn't adjustable with the tuning dial. Please help... I'm stuck at the house for a week with no tv!! :(

SOURCE: onkyo tx-nr801 net tune setup help

Below is the sequence that I made it work

1. download the latest firmware for tx-nr801 and net-tune central software at Onkyo website as shown below:
Click on "User Identification" at the bottom
(You'll need the serial number shown at the back of TX-NR801
to download it)

2. disable firewall in your PC or notebook and start
updating the firmware for tx-nr801
If firewall can't be disable, you probably can't go through this.
This step takes about 30 min.

(There is a document showing how to do this with the download)

3. keep disabling firewall in your PC (notebook) and install net-tune central (there is similar document describing the procedure too)

4. By pressing Net-Audio on remote controller (it can switch between mServer and iRadio fucntions if you keep pressing this button)

Could well be the quality of your cables. if you have high end cables the consult a service agent. if you have the cables that came with the products, go and get some better ones.

This might somewhat help. Today I went back .. I went HDMI out of the Cable box and DVD player into 2 of the TVs HDMI ins. The digital audio out from each, straight to the receiver and things are working ok. All speakers are working OK. Sound isnt as loud or crisp but unfortunately I found no other solution.

Son hit tv with ball no sound but....picture is fine

Perhaps you check all cables and connections. And look if all switches are in the correct position. He could heave accidentally have hit the mute button, or a button to switch to other speakers.

I almost can't believe something is defect inside the TV.

Iphone 4 takes and receives photos as negative images. How do I fix this?

Sounds like you may have accidentally enabled the functionality for visually impaired folk.

Found here: Settings>General>Accessibility>White on Black

You can set the home button triple click action to enable this mode, great for friends with iPhones, watch them freak out.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it and give a testimonial for my response

Thanks, Joe

Something happened with the sound. someone hit a button (unknown which one) on the remote and now there is no sound while watching cable. other devices hooked up to the tv sound just fine.


The sound settings in the sound set-up menu are different and saved for each input (video one, cable, etc.). Go to the sound set-up menu and select stereo and speakers on. Save settings if that choice is offered. You may have accidentally changed settings for one input to SAP or speakers off.

When I turn the air switch on a sounds comes on like from the fan but the fan is turning if i turn the swith off the sounds goes away. where is the sound coming from?

could be the fan hitting or rubbing on the fan housing or something has fallen into the fan motor housing thru a vent such as a paperclip, coin etc. and the fan is hitting that object. correcting either problem requires the opening up of the fan motor housing.

Denon avr-1706 receiver just shuts off

This sounds like the amps protector circuit has been activated due to thermal overload. switch it off for an hour or more to let it cool down, make sure your spkrs are connected properly, don't parallel. Try using a fan on the unit to get that heat away. Get a techie friend to give the insides a once over, and clear away any dust that has built up.

hope this is of some help,
Cheers Kimbo.

Makes loud noise while cooling. sounds like fan is hitting something. a/c is 4 years old, in the wall, problem just began July 2009. Lowering fan speed, or energy saver setting do not help.

That's because it probably is.Shut it off.Pull it out.Set it on a table by the outlet or a/c housing.Plug it into the same outlet.Keep fingers away from the blade and visually watch it.

My guess is the fan blade loosened on the shaft and needs to readjusted and tightened.Or the wires need to be moved out of the way of the blade and tie down(not on the fan blade either foo!!!).

Sony SVR-2000 Tivo problem?

This sounds like it might be interference from some component outside the TiVo. I'd suggest you try connecting the TiVo, and only TiVo, to another TV in your house (if possible) to see if the problem goes away.

TX 8410 Onkyo no sound

Well, I'm sure you've either fixed the issue or gotten rid of the unit by now, but anyway... perhaps the speaker selection was accidentally switched (A or B), or my personal favorite: "Tape 2 Monitor" was turned on. Even if you select something else, you'll still see "Tape 2 Monitor" displayed on the LED display. Hit the button again and it will go away and your sound should return.
