How can I hook up a home theater system to work with the regular tv?

Home DLP Q&A's
I have an LG 42PG20 Plasma tv and an LG LHT854 home theater system. I do not use a cable box to receive my cable. I get the sound ok when I watch DVDs but not when watching TV. I do have the HDMI cables but what am I missing? Any help would be great.
Thanks!

I have an audio/video receiver and hooked everything up to it.

OK, you are getting your signal by antenna, right? If you are using the internal
TV tuner you will need to send the audio system a left and right audio in from an output labeled “AUDIO OUT” on the back of the tv. It may require an RCA patch cable (like you use to hook up stereo equipment). The cable has two plugs on each end….red is for right. Hook it to “AUDIO IN”
on the audio system and the tv will send the audio signal to the audio receiver, where the signal is decoded and sent to the proper speakers. Keep using the HDMI cable for DVD’s!

Connect optical cable or composite cables ( red & white ) output from TV to Home Theater System input for audio.

On the back of the TV you will see labeled “digital audio out” and “optical”
On the back of the home theater system far right you will see “optical in”.
Get some optical cable, which goes by the slang name Toshlink cable. Connect the cable between the TV and home theater system.
On the home theater remote use the “input” key to get “AUX OPT”.
Alternatively you can also use the “TV –> HT speaker” button to directly select “AUX OPT”.
you will only get surround sound on HD TV channels if the program is with surround sound. A lot of made for TV programs are just in stereo.

Your TVs won’t pass surround sound on to the surround sound system except what it’s received over an antenna. If your cable coax is screwed directly into the TV and you are sending the audio on to the surround sound system then you will not get surround sound, only two-channel audio. If you screw the cable coax directly in to the surround sound system (if this is even possible) you will get surround sound IF the programming has a surround soundtrack.

sounds like you need a cable, plasma tv audio out to home theater audio in. it should be a three prong audio cable red, white,yellow or maybe the hdmi audio cable to the home theater box. let me guess you forgot to check before you bought it. OK; GET A PENSIL, AM ONLY GOING TO SAY THIS ONCE. check what you buy to make sure its compatible by this I mean the jacks are the same on both the tv and the home sys. Always get a tv with an ear phone jack, it can be used as an external audio jack to your home system. and make sure the sales person didn’t switch it to a different model before you pay for it. got it… home systems do not always come with all the right cables you need. so you may need to go to the store and get a cable that you do not seem to have now.

I looked at the picture of your back panels and find it surprising that a big tv like yours only has one audio output (and I usually like LG, how lame). Since the only output on your tv is optical you will have to buy on of those (also called toslink) and plug that INTO the theater sys to hear your cable tv. Get the cheapest one you can find –maybe Walmart, Radio Shack or Amazon. Basically you’re plugging both the dvd and cable into the tv and then sending the audio into the home theater so you can hear it. You can also just plug the cable tv into the tv and plug the dvd player into the theater sys but then you have to do and extra step and output the video from the dvd player (from the theater sys) into the tv so you can see it. Hope this helps.
