Question by boring_kind_of_anger: How can I hook up a home theater system to work with the regular tv?
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!

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.
