I have a LG 42" LCD paired with a LG LHT854 home theater and a directv HD receiver. I the satellite receiver and 854 hooked to the TV via HDMI and the satellitle receiver is connected to the 854 via optical cable. Great sound and with DVDs great surround sound, but with TV there is no sound from the 2 rear speakers???

you cant you have to use a fiber optic cable from your xbox to the lht854 then just hook the HD cable from the Xbox to the tv i have the same surround sound and had the same problem.

LG documentation states:

When you use SIMPLINK function, you have to

connect to the OPTICAL IN 1 jack to enjoy TV
sound to your speaker system.

Basically you need to have the Audio go from TV to receiver and setup receiver to that Input to output surround sound to all speakers.

If you have a cable box or satellite receiver, hook that output into the receivers input and that should work.

My setup is DirectTv HDMI output goes into the LG Home Theater HDMI Input 1, and LG goes HDMI output into the TV HDMI input 1.
so to watch DirectTV, I switch LG Home theater to HDMI Input 1. and TV is on HDMI input 1 (to view LG HDMI output from DriectTV, Blu-Ray, Vudu, etc.)

no just use the hdmi out on your tv

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!

optical audio cable from home theater to tv. can be purchased on line for a few bucks.

I would check the wiring suggestion in the LG LHT 854 and the TV.It may just be miswired.

Ok your dish network wont play through the LHT854? Which Dish network receiver do you have 211, 311, 625, 612, 722? From the owners manuel for the LHT854 it looks like you can only hook up the audio from another source by an optical cable, so how is the LHT854 hooked up to the dish network receiver?

(got the video to play through the speakers and not the audio) how do you see video in your speakers?

I ended up using the component in cable hookup and fiber optic digital audio instead of HDMI - works fine.

OK try to connect all to tv and from tv connect the sound in digital to H/K receiver and you will have sound at the receiver no matter what.
