SOURCE: Onkyo receiver audio problem

Called Onkyo and here is the solution they gave me.

1. Turn on unit.

2. Press and hold VIDEO 1 button.

3. While pressing VIDEO 1 button, press Speaker A.

4. You should see "CLEAR" on the display for a second and the unit will go on stand-by mode.

5. Turn on the unit again and check if sound is back.

Hope this helps.

You have a problem that was inherent with all Onkyo receivers from this period. You need to contact Onkyo because the microprocessor needs to be replaced. Last I checked, its about $80 from onkyo.

This is NOT an isolated incident as darn near every Onkyo receiver model had this problem.

Good luck...

SOURCE: Onkyo TX-SV 727 PROTECT mode

Generally, this happens when there's a loose connection somewhere, either internally, or with the connections. It usually happens when the volume's too loud, and it tries to protect itself.

I'd suggest you unplug everything from it, check all the speaker wires, and then try turning it on, without any devices connected to it.

If it works, turn it off, and reconnect devices, one by one. That should fix it.

If not, it's likely that there's a loose solder inside, and it needs to be sent out for service.

SOURCE: 1080P video via HDMI generates awful interference

Your Plasma's native resolution is 720P. Go into the Blu Ray's output setup. you can choose 480p 480i 720p 1080i and 1080p. Set it for 720p that should clear up the issue.You may have to run Component directly to the TV since you only have 1 HDMI input and you can run Digital coax or optical to your AV receiver for audio. On a 50" TV the difference between 720p and 1080p using "GOOD" cables cannot be seen by the human eye. Above 50, yes it is noticeable.
Hope this helps.
