All you are currently doing is getting sound OUT from the LG HT system. If you want sound from your cable or satellite, you have to run a seperate audio cable into the back of the LG system. If you are running a cable line straight into the TV you need to run an audio cable OUT of the TV so you get sound via the LG system.

Just bought a LG home theater system for my TV, my model number is 247FHD-T11, the theater system uses and hdmi cable, but my tv has not connect, what am I doing wrong?


It appears that television does not use HDMI to connect audio, only video. Sound is via twin phono leads. Here is the page in your manual.

HOW I GET SOUND TO COME OUT OV MY LG HOME THEARTRE SYSTEM USING AN OPTICAL CABLE FROM MY LG 37" LG3000 TV .AND HOW DO YOU USE THE SIMPLINK FEATURE ON THE SAME TV . NO INSTUCTION MANUEL. THANK YOU.


This is a manual that should help you, it may even be your model but, it shows hook ups and has a page about the Simplink:

Scroll down to manual, ckick on the one you want, and open. Typically, you would want to hook all video related units directly to TV, via HDMi, Component, RCA, etc., with the componenet video, you have to also have an audio cable, because the componenet does not carry sound. In other words, you want to hook things like, cable/sat box, DVR, etc., directly to TV then, use your digital optical out from tv to digital optical in on your home theater. You use your TV's menu to select what you are watching and you only have to use the one input setting on receiver to listen to all. If you try to route you units through the home theater system first, you may not get the best results and you may expierience lags between the video and audio.

Hi, I am having trouble hooking up my new LG home theatre system with my Rogers cable. I connected the home theatre system to the TV with an HDMI cable. The sound works with watching DVDs on TV and...


To listen to Tv program sound through your home theater system you will have to connect a pair of RCA to RCA cables (Red and White pair ) from the audio out socket of the TV ( some times three sockets Yellow/Red/White labeled Monitor out. Ignore the yellow as it is video out ) to the Aux or CBL/Sat input of the LG system. Then to listen to the sound through your LG HT system switch the Input selector of the LG to Aux or CBL/SAT. Will work for sure.

I have an RCA home theatre...model rt2910. I have hooked my PS3 via HDMI to the TV for the video and used an optical cable for the audio. I set the PS3 to send video via HDMI and audio via optical cable....


You should have the HDMI plugged into the Home theater unit. The theater unit then is attached to the TV using the HDMI out.
The home theater unit passes the HDMI through to the TV while playing the audio for you.
You will likely need to select the correct source on your RT2910.
Here is a link to the manual.

See the section entitled "Connecting to HDMI Components" for an illustration of what I have described above.

I have a LG LHB335 Blu-Ray home theater system, & a LG TV I can get Full surround sound when the blu-ray is play a DVD but not when just watching Reg TV. I use a HDMI, should I hook up sonething else ?...


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.)

Hooking up home theater


Run a regular RCA type audio cable from your TV audio out to your Home Theatre audio in. That is what I have done recently with my Samsung LCD and Home Theater. You then have to put your Home Theater on Aux 1 or Aux 2 to get the sound from TV. Ensure your TV's volume is off.
