Question about Zenith C34W23 34" TV

1 Answer

No Audio Out through the Optical OUT jack

I have a n older Zenith C34w23 HDTV which has given me exceptional service. I recently purchased an LG LHT734 home theater system. I am also connected to Dish Network's VIP222 HD receiver in which I receive HD service. I want to connect the system so that I can control the sound THROUGH THE C34W23 HDTV with the Dish Network Remote Control.

The C34W23 Users Manual says that I can connect the HDTV's Audio Optical Out jack to the Home Theater's Audio Optical IN jack; select the Optical IN input on the Home Theater system; leave the Home Theater system on; and control the sound with the "volume control" on the TV ... using only ONE remote control.

When I connect the system in this configuration, I get NO sound through my Home Theater system.

If I switch the Optical cable from the optical output of the HDTV to the optical output of the Dish Network Receiver, then I get true Dolby 5.1 sound, but I have to control it with the home theater's remote control. Also, I use a VCR connected to a standard A/V componet input on the C34W23 HDTV (I use the VCR almost every day). This is just too much juggling of remote controls ... and my technically spouse will never learn the system.

What am I doing wrong? Is the optical signal from the older C34W23 HDTV in a compatible format with the optical input of the new LHT734 home theater system? Am I doing something else wrong with the home theater system (I am selecting the "AUX OPT IN" input)?

Please help! I'm ready to return the home theater system and get my money back!

First and foremost when the chance comes along buy a Harmony remote. Your spouse will love the simplification. A couple of things, On the tv with the optical hose connected and the other end in your hand, do you see the light. Its not a laser and eye safe. Should be a red glow. If not, implies two things the tvs optical is bad or it needs to be enabled via tv menu audio settings. If you see the red glow, then its a protocol issue. Verify your tv is setup on the proper audio mode that your receiver is wanting to see. Probably PCM. I am not directly farmiliar with the tv, but using the dish receiver as a reference (you know its working) set the audio options on the tv similar to the dish receiver. IE pcm, dts, etc.. Let me know thanks

Actually not a problem, just trying to find out if this tv is an hdtv......assuming not because of the age, but just wondering how to tell if it is. Thank you


You are correct. This TV is a 1997 model, NOT a HDTV. Modern HDTVs have HDMI jacks. Older ones had DVI jacks. This TV has only standard definition video inputs.

Picture flashing


If it is an older "hd" tv it is probably 'hd ready.' Check for adjustments on your source. The tv will most likely only display the highest resolution it is given.

Hooking up a dvd player


as you say that it is old tv so there is a possibility that there may not be audio video socket where dcd player can be connected. OR You will have to purchase one video RF converter.RF converter contains one video input in yellow color & two audio input in red & white colour & one cable connector as output. Connect the dvd output to this converter & tune tv program in which place you receive dvd signal.
