Audio &Video signal goes off .ATtimes when we switch on TVit takes long time (even 10 to 15 mints)to see and hear audio

Record players have a phono output that is much lower level than other audio equipment. If your receiver has a phono input that will have a preamp to adjust the level. Or your turntable may have a switch between phone o or line level and that would increase the volume as well. Most audio signals are line level but phonos are a magnetic signal that is much weaker and needs to be Amplified by a preamp in your receiver or in the unit itself.

All TVs today are actually computers which also receive TV frequencies. The audio has to be decoded from the digital signal then goes to an analog audio amplifier. When you hear no sound with the picture do you hear anything coming out of the speaker? A hissing sound when the volume is way up?

If you hear a hiss then the amplifier is working but not getting anything to amplify. This could be due to a bad solder connection or a problem with the CPU and/or a switching circuit. Without a schematic I'm guessing here.

The bottom line is, there's probably nothing you can do to fix it unless you're used to dealing with SM (surface mount) technology and can touch up all solder connections from the CPU to the audio amp.

Whoever is fixing the TV should be able to tell you where you're losing the signal from the RF decoder to the amplifier as long as the problem is not before the decoder (which is probably all in software that the CPU runs.)

Check your audio cables,, maybe you have a speaker switch turned off. Or a source selection switch, or even a mute switch?

nienqajm, Tell me if you hear anything if you connect a set of "ear buds" to the "mint" green color audio output connector "jack" on the pc!! Play a video clip with audio at YOUTUBE and you should hear something if audio not on mute. 12fixlouie

Many people who use A/V receivers use them to switch only the audio. ie, hook up all your video sources to the TV, and switch between these sources using the TV remote. Just connect the audio cables from your video gear to the Onkyo. The reason is that video signals are more susceptible to problems in A/V receivers than audio signals. better to connect the video sources directly to the TV.

You may want to ask for more clarification about this.

Here is the solution - in the audio settings you have to select optical out or it will still use HDMI. Regards, Joe

What do you hear? Do all other modes work ok?

If Audio Select (Page 44 and 98) is set to HDMI you will hear silence if no HDMI signal is present. I think AUTO is the best choice here.

-------

On Page 98 of the manual it says a bunch of things concerning automatic signal detection and input selection.

Initial configuration D) INIT. CONFIG
Use this feature to select the settings of the audio input jack select, active decoders and extended surround when you tum on this unit.
....

Audio select AUDIO SELECT
Use this feature to designate the default audio input jack select setting (see page 44) for the input sources connected to the DIGITAL INPUT jacks when you tum on the power of this unit.


HDMI set E)HDMI SET
Use this feature to select the component to play back HDMI audio signals.

Support audio S. Audio
Use this feature to select whether to play back HDMI audio signals on this unit or on another HDMI component connected to the HDMI OUT jack on the rear panel of this unit.
...

CHOICE = RX-V663

FUNCTION
Plays back HDMI audio signals on this unit. The HDMI audio signals input at the HDMI input jacks of this unit are not output to the HDMI component connected to the HDMI OUT jack on the rear panel of this unit.

CHOICE = OTHER
HDMI component connected to the HDMI OUT jack.

NOTES
This unit transmits audio and video signals input at the HDMI input jacks to the HDMI out jack only when this unit is turned on even if "S.AUDIO" is set to "OTHER".

I'd look in these areas for specific guidance.

The audio inputs on the receiver need to be set to receive the Optical signal on the switch you set the ps3 to. ie Game, DVD, AUX. Each switch needs to be set to receive the audio signal coming into it. Usually on the remotes setup feature.

AT THE START OF THE SET UP MENU CLICK ON IN/OUT ASSIGN.THEN MONITOR OUT APPERS,THEN HDMI NO,FLICK THIS TO ON.IFF YOU GET PICTURE AND NO SOUND GO TO THE HARDWARE SET UP AND DOWN TO HDMI AND SWITCH AUDIO OFF.

HOPE THIS HELPS.
