Is the signal connected to coaxial- a digital spdif? If you are dealing with analogue audio connect them to RCA's. Hope this will help.

I have an older Panasonic HDTV Viera and I am trying to hook up a Panasonic DVD/sound suround model SA-HT920 and am not having any luck getting it too work. I have the sound turned off on the tv speakers...

What does the TV really need from the receiver in all of this? Minimally, Component video for the DVD and managing the SA-HT920, not much else.

A TV is not normally an optimal source of audio.

Your broadcast TV-related sound would be higher quality and easier to obtain if you got it from the Cable or Sat box you probably have. Route ITS BEST (digital multichannel) audio directly to the SA and and its BEST (HI-DEF) VIDEO directly to the TV. You could also run vanilla analog audio to the TV so you can watch news in lo-fi audio on the TV.

The exact model of TV would be helpful to know as audio capabilities may vary.

Should you still feel the need to run TV-originated audio to the SA from the Viera through its headphone or audio output, connect that to any available analog RCA input.

Connection of a jack into the audio output will pass unmodified TV audio to the SA. That's a good thing as the REAL audio electronics needs an unmodifed source for best results.

Our SA-AX7 says overload. What do we need to do?

Do not continue further. There is a short circuit in the power supply or output amplifier stage. Disconnect power. The unit is preventing a fire or further damage to the system. Also, check the speaker output terminals for wires shorting the terminals together. Otherwise, an audio repair shop must isolate the problem. More than likely a transistor has shorted in the output stage.

I was using my vsx D510 with a hiteker dvd player

Each digital input is assigned a name and a function by you. You have to dig out the manual and assign the digital inputs.

My $.02. Why do you not want to use the coaxial imputs? There is no functional superiority of one over the other BUT coaxial is a) cheap, since it uses standard RCA cables; b) adaptable, since you can splice or split them among two devices; c) not delicate or prone to failure due to tight bends. I share one coaxial input between two digital device with an RCA splitter cable. Just have to make sure to turn the one I'm not using OFF. Try that with optical.

NO AUDIO/set up problems

For this Sony, you have to use separate audio cable(s). Either optical in BD or Digital Audio in DVD (single coaxial cable will do the trick) I bet the display says UNLOCK. I had the same problem, very dumb.

Good day!

Technics surround sound system

Use whatever TV sound output conforms to your receiver's input. If an optical or coaxial digital sound output is available, that is the way to get 5.1 surround sound through the SA-DX1050. But you have to assign the correct input (COAX, OPT1 or OPT2) to the selector (TV, DVD, CD). See pp 12-13 of the operationg instructions for D-Input instructions. If you don't have the manual you can download it at

Digital optical from DVD player produces no audio

Hi, It sounds like your receiver is still looking for audio on the coaxial connection, rather than the optical.

1. Make sure the optical connection is between your DVD player and the LD/DVD Optical In on the back of your receiver.
2. If you have a monitor connected to the receiver to show the on-screen display, click Setup from the main menu, click Input Mode, then, next to LD/DVD choose Optical. It may be set to coaxial, analog or auto.

Alternatively, choose the input source on the front of your receiver (LD/DVD), then press Input Mode button (bottom right, near the input selector) till it displays Digital Optical.

If all else fails, reset the receiver by:
1. Turn off the receiver
2. Hold down DISPLAY and PANEL UP/DOWN buttons and press power.
3. All Clear should appear on the screen.

Use caution, however, as this will erase all the settings in your receiver.

Nope. That's the coaxial digital audio input. Thats the one to use for your dvd players digital audio output.
