My tv plays through its own speakers instead of through my home theatre speakers. I have a satellite receiver, samsung home theatre system, as well as a panasonic blu-ray player hooked to my panasonic tv.

A Samsung home theatre system can make watching movies at home like going to the theater. Proper setup is essential to get the full benefit of the Samsung system, which is available in 5.1 and 7.1 channel surround sound configurations.
Typically the final step in setting up any home theater is connecting your TV to your system.
Like most home theatre systems, your Samsung home theater receiver will allow you to plug all of your components into it, meaning you only have to run a few cables to connect your television to your system.
Make sure your playback devices are properly connected to your receiver.
Whatever playback devices you use, make sure they are plugged into the appropriate inputs on your receiver.
DVD and Blu-ray players, satellite boxes and cable boxes should all be plugged into video inputs, and CD players should be plugged into audio inputs.
Your receiver will have labels on the back panel indicating into which input you should plug your devices.

Connect the video out to your TV's video input. Make sure you use the correct cable to make the connection. For newer receivers, the connection will likely be either HDMI or component.
If your receiver has an HDMI output, use an HDMI cable to connect the receiver to the HDMI input on your TV.
If your receiver uses a component output, use a component cable to connect your receiver to the component input on your TV.


Connect the audio output of your TV to one of the audio inputs on your Samsung receiver if you want to output your television's audio through your home theatre system.
Most recent TVs will either use an optical cable or a digital coaxial cable to connect to the receiver, allowing you 5.1 channel surround from your television.
If you have an older set, you will likely have to use standard RCA cables.


Turn on your receiver and press the "Setup/Menu" button on your receiver's remote.
When "Input" appears on the display, press the right arrow key on your remote to select TV from the list.


After selecting TV, press the up or down arrow keys on your remote to select the audio input jack into which you have plugged your TV's audio cable.
Press the "Exit" button on your remote to exit the setup menu and lock in the settings.

If you're not an electronics junkie, hooking up your surround sound can seem daunting.
There are so many wires and settings that it's understandable why some people might rather pay someone else to do it for them.
But you can do it yourself as long as you make sure the speakers are positioned correctly; the wires are not only plugged in all the way, but plugged into the right places; and the settings on your television and amplifier are set up correctly.

Check to make sure your surround-sound speakers are correctly installed.
Locate the test function on your surround-sound remote control or amplifier panel to do this.
You will know your speakers are hooked up if sound comes out of each speaker during the test.
Make sure your audio cables are hooked up properly.
Make sure the audio cables running from your television to your amplifier are plugged in correctly. The red and white wires should be plugged into the "Audio Out" spot on the back of your television.
Those same red and white audio wires should be plugged into one of the "Audio Input" spaces on the back of your amplifier.

Turn on your television.
Locate the "Menu" button on either your television remote or your television set.
Scroll through your options until you find "Audio Mode" or a similar naming convention.
Select it.
Scroll through your options until you find "Digital Audio Out," or a similar naming convention. Choose it.
Scroll through your options until you find "Dolby Digital Out." Select that option.
Power your surround-sound system on.
Make sure you have the correct audio input selected.
After the correct audio input is selected, make sure you actually have the Dolby Digital aspect of your surround sound system turned on.
The default for most surround-sound systems is the standard two-channel, stereo output.
Set up a home theater

Check the region and picture settings on the home theatre's dvd player, it could be set to put out a component signal, or it could be set to a PAL region rather than NTSC

Remove the batteries and hold down the POWER button on it for 30 seconds. Then replace the batteries with fresh ones.

Hope this helps!

because you do not have the dvd player hooked up to the tv, if you want it to play through the tv then you need to have the dvd player connected to the tv.

you are to buy component to HDMI adaptor.

why it doesn't come. just connect the RCA cable to the output pins of TV and connect them to the input female jacks of home theatre receiver. or if the TV has optical out and the home theatre reciever had optical in. thats the best option. just connect one optical cable to enjoy the 5.1 sound. tell me clear problem if u r nt solved.

if you got all the lead you should have fibre optics which connects from dvd to tv and then set your dvd to digi in. you should get the sound. i have same cinema system and i have done the same

if you use cable and have a cable box or sat. and have a box you need to get an optical audio cable and hook them between the to boxes. just did this with mine today

That is because you didn't have the audio input connection right.
1. HDMI cable going from the Samsung tx72 output to Your Samsung TV HDMI input 2.
2. Non HD directv box Left and right audio output should be connected directly to the Samsung DVD receiver under Satellite input.Select"Satellite"for the sound from your Samsung tx72.You are good to go!

i dont think you are suppose to have the tv speakers on with the theather systems speakers on because of the magnectic field can cause your tv speakers to mess up.
