I would advise you to call LG's customer service at 800-243-0000 to set up service. There is a service bulletin about this issue specifically for your model. Your set requires a simple software update to fix the audio delay with HDMI issue. You can ask LG's customer service to refer to bulletin #0IVL20080379. Hope this helps.

It's possible that the TV broadcast isn't in true surround, and is only dolby encoded.
You can try going back to the component hookups, but I am not sure that will solve your issue.

HDTV HDMI hookup


Connect a HDMI cable from your source device (cable box, Bluray, satellite receiver) to your HDTV for High Def video and audio. This is the best hookup for HD, even 1080p. For 3D HDTV, make sure to get a high-speed category 2 HDMI cable. Select proper HDMI input on the TV using the remote. HDMI means High Definition Multimedia Interface.
Any newer digital TV (made after 2008) should have at least one HDMI input.

DVD PLAYER to TV HOOKUP


57b6c82.jpg

Basic DVD player hookup to TV cable diagram. RCA cable (yellow) video and RCA cables (white and red) audio. This is all you need for picture and sound. If your TV only has a single RF input, then you need a RF modulator. RF modulators accept the yellow, white and red cables and output a coaxial cable to the TV single input jack. Usually the TV is tuned to channel 3 or 4 to pickup the RF modulators output.

Alternative connection options are many and include HDMI for HDTVs, component video and for sound, surround sound digital audio connection using optical or coaxial digital audio cable.

Surround sound requires a decoder such as a A/V receiver with Dolby Digital 5.1 or DTS 5.1 or more. 6 speakers connected to the A/V receiver surrounds the listener.

Bluray players will play DVDs and Bluray discs. Bluray gives you High Definition video and typically connects to a HDTV using a HDMI cable.

How do I hook this up to a COMCAST Cable Box...or do I hook it to the audio of the TV? Are cables the best or should I just buy an HDMI cable?


Cable (and any source) audio should go digitally and directly to your AV receiver. HDMI would work, too, but the TV would be the best place to send the HD video if you only have the one HDMI output at the Comcast box.

OTOH, I compared both HDMI and the component video hookups to my HDTV and could not see the difference. So I run my BD on HDMI (because it is by FAR the best video the TV will ever get) and component video from the HD cable box to the TV (because all broadcast video is bit- and bandwidth-limited somewhere along the line).

TV audio almost never originates with the TV unless it has an antenna, so why would you want to feed its audio to the receiver?

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!

Low volume on LG HDTV


I encountered the same thing using the HDMI interface on my new TWC cable box (Motorola DCX-3200). After a little bit of research, I finally fixed it by changing the digital audio mode in the cable box using this procedure:

1. Be sure the TV is on and connected to the cable box.
2. Using the cable box remote turn power OFF.
3. Immediately press the MENU key on the remote. The USER SETTINGS menu should appear on the TV screen.
4. Select the ADDITIONAL HDMI SETTINGS >>> menu item.
5. The ADDITIONAL HDMI SETTINGS menu will appear.
6. Scroll to the AUDIO OUTPUT item and select this.
7. Change the setting from AUTO to L-PCM.
8. Return to the main page
9. Using the remote, cycle power OFF.
10. When the cable box is turned on again, you should be good to go.

I realize these instructions are specific to the DCX-3200, but there may be a similar setup option available in your cable box as well.

The problem here is that the cable box is by default configured to use Dolby Digital audio, which requires an additional 10dB of headroom to deal with the boosted LFE channel. If the cable operator hasn't taken pains to set the system up correctly (and most haven't, apparently), the digital audio level sent on the HDMI interface will be approximately 11dB down from normal analog line levels on the HDTV channels. Changing to straight linear PCM sets the TV receiver audio level on the HDTV channels to match the levels on the non-HD channels.

The only problem with this fix is that if you intend to feed a Home Theater receiver that uses Dolby Digital processing with the cable box output you will lose the Dolby encoding feature and be forced into straight 2-channel stereo. For a simple installation like mine where I'm just feeding the TV, this fix works fine. If you have a more complex setup that takes advantage of Dolby Digital features (when it's available in program material), you may have to live with the problem.

For a technical reference on why this happens, see http://www.megahz.com/specimages/Dolby/LM100%20Cable%20App%20Note%2011-05.pdf

Hope this is useful.

Hookup diagram for Yamaha avr-863 receiver


It's the other way around.

Hook up the Cable box to the Amp; and the blu-ray to the amp, then connect amp to LCD.

you want to use the best available options for audio:
HDMI > Digital Optical > Digital Coax > standard RCA

And the similar for video:
HDMI > Component > SVideo > RCA cables

I would connect Blu-Ray via HDMI to Amp, and Cable box via HDMI to Amp. If your cable box does NOT support HDMI, but you have an HD package, ask your cable company for an upgraded box.

Connect the HDMI outputs on your various components to the HDMI inputs on your receiver. Connect the HDMI output on the receiver to the input on your TV. HDMI incorporates digital audio, so no need to buy optical audio cables. If your receiver does not have HDMI inputs for all your components, you will need to make a choice. HDMI = Best, component video + optical audio = second best, S-video+ optical audio = third best
