You will need an optical audio cable for the system to work in surround sound with anything other than the DVD. They are not expensive Teh optical cable will run from the TV to the home theatre.

    when used with VSM you don't get a real sound; what you get is back ground noise which is not as loud as the front speakers

Try to check the settings of your surround amplifier. The decoder might not be able to send audio signal to the rear speakers due to the TV source audio input. You can check the modes available for your type of audio decoding. hope this helps.

Bought a LG Blu ray DVD Home theater system last weekend and set up with LG lcd tv and has been working fine till today. We had the radio on and I turned the TV on and the two rear speakers do not work...


Hello,
In a surround sound system, the correct way to listen to music is in stereo mode which will play out of your left and right channels and your subwoofer. When viewing a movie with surround sound, then you should use your rear speakers. The key element to remember is that rear speakers are only intended to play your sound effects, and will not play full range audio. Thats what your fronts and center are for. If you simply want to override this, than you will need to select the direct sound field on your receiver and than it will send full range audio to all speakers connected. Most likely, its not going to sound that good. If you dont know what each sound field does, here is a list and function of the most commonly used ones.
Stereo-Front Left and Right speakers including subwoofer
Dolby Digital or PLII Movie-these are the bost options for your surround sound
Direct-All speakers connected get full range signal
Good Luck

Most TV stations you watch don't send a surround sound mix so you won't get anything in the back speakers. DVDs generally all have a surround mix which is why it sends to all speakers. What you are experiencing is normal, Bob.

Rear Speakers dont work


THe rear speakers are usually for the surround sound experience. What kind of movies do you watch? Usually the action movies have a lot of surround sound, calm movies not so much. And for the music, the same thing applies. Atleast for my system.

Hope this helps.

I need help hooking up my tv and dvd player to my surround sound


for your dvd player you just go from audio out on the back of the dvd played to the audio in on the surround sound. and you would do the same for the tv if it has an audio out. your surround sound shoud have more than 1 audio in. and then when you swicht from tv to dvd you might have change the channle, setting, source, or what ever it might be called on the surround sound. and if your tv does not have a audio out contact me at swinginflames@gmail.com and i try to help you. hope that works :)

Reciever only allows 2 channels(speakers) at a time.


If the amplifier is not receiving a surround sound signal, you will get nothing from the rear speakers and probably nothing from the front centre. Play a dvd in dolby surround and it will work.

Lg home theater to lg plasma tv


This is a typical problem with TV broadcast UNLESS you use a matrix DSP surround sound mode, most DVD audio is either Dolby digital 5.1 surround or DTS multi-channel surround sound, unless you are viewing a HDTV broadcast with 5.1 Digital sound connected from the TV to the receiver then you are probably receiving a 2 channel Stereo sound format, I would suggest that you try to set your TV input mode to a audio Dolby Pro- Logic which will yield 5.1 and should engage all speakers.

This is not a problem, this means that your system is working. Polar Express was recorded in Surround Sound with separate tracks for each speaker channel. In most movies you will find that the rear speakers will only play certain sound effects so that it appears they are coming from behind you (gun shot, train, fireworks). Most of the diaglouge will come through the center channel and music/effects through the front left and right, with bass coming from the subwoofer.

Now, you can still hear more from the rear speakers if you like this enveloping effect, or if you like your music coming from all directions. There are Sound Effects options to have the front and back speakers always playing the front track, there is Dolby Pro Logic II that turns stereo sounds (like many TV shows) automatically into 5.1 Surround Sound, and you can also individually change the volume of each speaker.

These are all explained on page 29 of your owner's manual under Sound Options. If you need specific button to button help, let me kow.

Surround Sound Not Playing For TV Programs


Greetings jdm12,

I can understand your problem, I have some what of the same issues with my home theater setup when watching events. One of the only suggestions I can make is adjusting the "Dolby Pro Logic II Mode". After reviewing your owners manual it appears you should be able to change the mode by pressing the PL II Mode button found in the lower keypad on your remote. It appears the options you should have are Music - Cinema - Pro Logic - Matrix - Stereo. You may want to try Music or Stereo when watching your events. In Stereo setting it should provide sound out of the front speakers and sub-woofer only. In Music, there are more processing that is done so you could hear more then just the front speakers.

I hope this makes your next your next PPV Party a big hit!
