Question about LG LHB953 Theater System

2 Answers

I have an LG all in one home theatre system, LCD TV and Direct TV satellite box. It is all hooked up and working fine except I only hear the sound through the speakers when playing a dvd or radio. The sound only plays through the TV when I am watching satellite. I hooked a fiber optic cable from the TV to the AV receiver, but still no sound through the speakers.

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!

From which connectors to which on the TV (what brand/model?) did you run the optical cable?

Please clarify: "The sound only plays through the TV when I am watching satellite". Do you WANT the sound to come from the TV; or do you want to hear the TV program audio from your LG??

Which way are you envisioning audio to flow - TV to receiver or receiver to TV? There is NO audio output from the LG to anything. Think of a TV (monitor) as simply that which produces the picture. The best sound-handling and -sourcing will be at the receiver.

Generally, most externally-sourced TV watching originates with a cable box or satellite. I believe you have the satellite function figured out. Cable will be similar, but you may not have the required available inputs. There will probably be some sort of analog or digital audio output on the cable box. Connect it to the Aux In or appropriate available Digital In on the receiver as applicable. Select the appropriate input on the LG when watching TV.

Hint: if you have to share the only Coaxial Digital Audio Input on the LG, that is possible. Get an RCA splitter and run it to both sources. Just make sure the one you're NOT watching/listening to is turned off to avoid having an excessively verbose digital conversation going on with the receiver or between the two digital sources. I do this in my system.

Having browsed the user manual I wonder if you plugged in the Sony BDV T57 Home Theatre System while the Polaroid FLM-2632 tv was powered down via the optical cable .
Then powered up the Sony BDV T57 Home Theatre System first and then powered up the Polaroid FLM-2632 tv
Maybe the Polaroid FLM-2632 TV has to detect that the Sony BDV T57 Home Theatre System is connected and powered up when the Polaroid FLM-2632 powers up. To activate its digital audio out ????
The note part about only being available only under HDTV (cable/air) mode. Might be the cause of your hassle also ?

If you are talking about a bran new system that you just bought, look on the packages, especially the TV becuse usually they bring a "quick connection" guide. If no, there are various kinds of connection that you can use. First definitvely the direct TV box must go to the VCR and from it you have an output to go to the antenna input of the TV. Now you can connect the audio output from the tv to one of the inputs in the home theater (can be "TV", or "VCR" or "aux") but, better results you have if connect the audio outputs fronm the direst TV to the home theater, this allows to hear music channel without using the tv just to see what channel is and you can turn it off the tv then. let me know which connction you prefer because there some that offers better video quality, as the S-Video wire, as well the optical output that comes from the direct tv box, which is the best for the sound providing the very good experience with the 5.1 surround experience.

Sound issue on LG 42LG50


make sure the dish network menu settings in setup under audio are on high. Some tv's require it to be off. Try both and see what works. Also the delay is caused by digital conversion. new stereos have settings for this delay and they have delay boxes for sale online. You could try to change your delay settings on your stereo surround to help. I had to do this.

How to redirect the sound of my new LG 52" HDTV LCD to my LG home theatre?


Flemflam-   There is a couple of options here. If you are using a DirecTV Receiver or a box from the cable company then you want to run the Audio out lines to your Audio/Surround Sound Receiver. If you are running cable directly into the TV then you want to use the Audio Out Plugs on the TV. In some cases there is no Audio out but there is a Headphones out. In this case you can run a Mini-Plug to Composite Audio cable to the receiver.    You can also Call 1-800-GeekSquad and they will dispatch an Home Theater Installer to resolve your problem! They are great for Turn Key Solutions!

How to redirect the sound of my new LG 52" HDTV LCD to my LG home theatre?


There sould be audio outputs on the back of it, and the manual should clearly show how to set up a home theatre with an external sound system and all.

I don't know what kind of sound system you have, but I think it might be best to connect your video source (typically DVD player) to your sound system, as it usually can be done better that way. No need to introduce another link in the chain (your TV) that could degrade sound. Also any external tuner could (should) be connected to your sound system directly.

If you use the internal tuner in your TV to watch TV the audio out is your option. Best way to get this right is to consult the manual. They usually have some diagrams that shows a few options of how to do it.
