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!

if the Comcast cable box has an HDMI output, it should connect directly to one of the TV HDMI inputs. Then connect the LG DVD unit HDMI output to the second HDMI input of the TV. Use two HDMI cables. Do not buy the expensive Monster HDMI cables. If you have already done so, I recommend you take it back for a refund, then buy the low cost HDMI cables which will work just as good and then you can bank the savings toward a new Porsche Boxter!! Now we have the video connected from both the cable box and the LG system.
Now--what do you do if the cable box does not have an HDMI output--just use its component output and your component cable (red, blue and green) to connect to the TV component input. This will still get the video to the TV and good HD pictures. Hum--do you have an HD cable box? You did not say and I just assumed that you did since you got the HDTV. If not, let me know with a follow up question and I will assist in that area further.
Now for the audio connections--The DVD player will not need any connections since it in the LG unit. The sound will come out the speakers when you start playing the DVD. The cable box is where we get the TV audio to feed the LG unit. If the cable box has an optical output, use an optical cable (again the low cost one)and connect to the optical input on the LG. This will get the TV audio to the surround system. If no optical output, use the red and white (left/right) audio connections and connect to one of the two the LG audio inputs. To hear TV audio on the LG speakers, just switch to that input or the input associated with the optical input.
To watch DVDs, switch the TV to the HDMI input to which you connected the LG unit. For TV, go to the other HDMI input (or component input). Switch the LG to the audio input to which you connected the cable box to get TV sound.
Hope this gives you food for thought. If so, and you have more questions, just come back in with a follow up.
You need to go out and purchace a audio optical cable for your unit, it does not come with it because the device will give you sound with a DVD just not with your TV. the optical cable hooks up to the back of your TV and then to the back of your LG LHT854 player. You might have to adjust some of the options in your sound menu but once you have the cable you will be on your way to surround sound with all of your devices.
Make sure the output in your tv menu is set to external speakers. Any digital optical cable, or RCA jacks hooked up properly from the TV's out put to the receivers input should work just fine. Take your time, retrace your steps, and make sure each cable is in the correct input/output. And make sure the receiver and TV are on the proper settings. Good Luck, and thanks for using FixYa!
Can you explain a bit more please. What exactly is the problem? Are you getting any picture or audio through to the TV? Are you getting any picture or audio through to the home theatre? Have you got the home theatre setup via HDMI? Have you connected the audio from the cable to the home theatre via optical or phono? What model is your LG LCD HDTV? I already have the manual in front of me for your home theatre system. If you can give me some more information I can help you out. Thanks.
Check wiring from DVR to TV and surround system...TV may now be getting audio signal from DVR via HDMI/DVI cable. If so, the Bose needs to be connected to either optical/audio out on DVR, or on the TV's audio out jacks. If there is only one cable from DVR to TV, that is probably the case. This is just a general solution, if it doesn't help, reply with make & model #'s of all devices involved, I might be able to help more.
What I did was turn on the system, don't put in any dvd in, or select an output 1 or 2. Press Menu on the remote, the display on the system display, not on tv should show Speaker, and other options. Select Input, select the one you want to use as the Optical Sound by press enter, then it will ask you on the system display input or optical sound input. Select optical input and press enter it will then say saved. You can then hit exit til goes back to where the display is back on main screen, or just wait til it exit by itself.
Run a regular RCA type audio cable from your TV audio out to your Home Theatre audio in. That is what I have done recently with my Samsung LCD and Home Theater. You then have to put your Home Theater on Aux 1 or Aux 2 to get the sound from TV. Ensure your TV's volume is off.
