Question about LG LHT734 System

3 Answers

Rookie to Sound System

I'm totally new to Home Theater Systems but I'm mostly good with electronics. I just hooked this system up today to my 42 inch Olevia flat screen. I've got the HDMI hooked up and when I go to watch a DVD, all the speakers work. Then I switch back over to regular tv and only the front two speakers work. The sub, center, and back two speakers won't make a sound. What is the problem with it? It seems like it's somethign as simple as switchign the mode but when I try to bring up the setup on the tv, it won't come up. Again I switch back to HDMI and the setup menu will come up and all. Someone please lend me some help.

My Olevia, although it is a different model, will tell me if the TV program is being broadcast in surround sound or not. I would make sure that your program is in 5.1 because you might not have any problem at all. On my remote, I push "Display" twice to see audio channels.

NO tech, just your TV signal probably isnt digital. Why would you get 5.1 sound through a analog tv signal?

Connecting a panasonic surround sound to a sanyo tv


if you have this option, use a hdmi cord from the dvd output to the input of the tv.most new tvs have several hdmi connectors. Then use a fiber optic cable from sound system to the audio input of the tv. between the both it should sound like a movie theatre. thats how i hooked mine up. good luck

Hooked up home theater system, sound but no picture


are the red and white for "audio in" to the theater system receiver and the yellow cable hooked up to "video out" on the receiver and "video in" on the tv?

Typically most theater systems do not have "audio out" connections because they produce the audio. The receiver will have several "video out" connections, one of which needs to go to the tv.
