How do i get surrond sound for just tv shows

You should be able to run an optical audio cable from the Verizon set-top-box to the optical audio in on the surround sound system

how to get rid of captions on T.V.screen

TV's are not sources of multichannel audio. The best you'll get is stereo analog. Get the best TV-related audio from the same source the TV gets it - in this case the Cable Box.

Get the TV audio from the Dish box directly to the receiver.

I had the same thing just happen and I used the following instructions from the Vizio Website for "humming sound" on tv and it worked. My sound is now working!!!!

1- Power off TV

2- Unplug TV from outlet

3- Press and hold in the power button on the TV for 30 seconds (while it is unplugged from the wall)

4- Release the power button

5- Plug in the TV into a different outlet

6- Power the TV back on.

Reset the TV settings.

Hook your Insignia box between your antenna and your television. You still need the antenna.

This is going to be a bit tricky with this model, since either your Cable or Sat box will need a Digital Audio Out, and you will need to purchase a Digital Audio cable. If your sat box has a digital audio out, connect a digital audio cable from the sat box to the digital audio in on the back of the Samsung. Then connect a red and white AV composite cable from an available audio out on the back of the cable box to the "Aux In 2" on the back of the Samsung - this may only allow stereo sound, however.

Your absolute best bet (and the simplest connection) will depend on whether your TV has a SPDIF OUT or Digital Audio Out (they are roughly the same). If your TV has a Digital Audio out, connect a digital audio cable from the TV to the Digital Audio IN of the Samsung. Now you will get sound from any cable, sat, or any other type of box that is connected to your TV.

most programs don't have the 5.1 so you won't hear it

HDTV is not carried via coaxial cable from tuner, you need HDMI or the 5 RCA cables that are different colors. I forget if they are called component or composite, I think they are called composite, the R and W are sound. If you run the HDMI or composite cables to your TV, there should be a variable out or audio out on the back of the TV that outputs ANY sound coming into the TV, like Wii, DVD, tv, etc. So if you want to listen to tv sound, just pipe the audio out to the receivers available input and turn it up. Cant be used with mag input (turntable) all others are compatible. Did this answer your question? Sat cables are usually kept under 130 ft from the dish, and the dish receiver can output coaxial signal over 400ft on RG-6 cable. HDMI is limited and can get very expensive. Does your sat box have a coaxial digital out (orange RCA) you can use that if your receiver can read it, usually associated with the DVD input or video input, but only for digital encoded programs.

Plug the TV to an open channel on your receiver via this output:
*Rear, 1 x Digital audio output (coaxial) ( TOSLINK )
This will look like a single RCA output plug.
Set that input channel on your receiver to some sort of virtual surround mode because it doesn't look like your HDTV has a decoder in it (meaning it will come out stereo and the receiver will have to fake it).
Turn the volume all the way down on the TV and use the receiver to control TV volume just as you do with DVDs.

*Substitute this with the digital audio output on your set top box if you are sending video only to the TV from the set top box (component, DVI or s-video connections). So video goes to the TV, audio to the receiver.
