SOURCE: Help With My Rear Speakers

i was told by a rep from lg that i could only get the rear speakers to work with a dvd only...i just bought this new and a 42" lg4230 lcd so i could have "surround sound on everything...it sucks unless someone can tell what is wrong...any help would be appreciated...i already did the setup and went thru all the speakers but wont work when i want it to.

SOURCE: sound doesnt sync up from direct tv to the speakers

(IF YOU"RE TALKING ABOUT SOUND LAG) The LG home theater system audio setup has delay settings, set delay to 0 ms to get rid of sound synchronization delay.

(IF YOU WANT DIRECTV SOUND FROM SPEAKERS) I used an optical cable from the back of the directv receiver to the Home Theater receiver. You can also use an RCA cable.

SOURCE: the surround sound only plays on dvd not tv

most tv shows will only be broadcast in 2.0 not 5.1 or higher. if you have a converter box, that may also be the problem.

SOURCE: I have an LG all in one home theatre system, LCD

OK. For all you regular Joe's like me here's the fix--plain and simple! I have Dish Networks HD receiver, an LG Home Theater System (LHB953) and an LG HD Television - although I suspect this applies for most LG TV-to-LG Audio Systems used in combination with a HD TV). My problem lied within the LG to LG setting known as SIMPLINK which tries to "auto-configure" everything between LG to LG devices.

Do this to make your HD TV (using Dish/DirecTV) play it's HD video display from the satellite provider but play the audio over the LG surround sound speakers:

1. Plug a HDMI cable from your satelite receiver's set-top-box to your HD TV. This will carry your HD "video" ONLY. Click "Input" on the TV remote until the HD video signal shows your desired TV channel from your satellite provider.

2. Plug an HD Optical cable (the one with the red laser) from your LG HTS (Home Theater System) to your satellite box. This will carry your HD "audio" ONLY.

3. This is the magic everyone seems to be overlooking. On the LG TV remote, go into the menu options and disable SIMPLINK by setting SIMPLINK=OFF. This feature allows the video and audio signals to be split over 2 different ports: HD video goes over the HDMI cable and the audio to go over the HD Optical cable.

Hope this helps!
