Without the specific LifeStyle model # it's not easy to say for sure, but it sounds like you might have a composite cable plugged into a component video output of the Bose. Assuming it does not have HDMI output, it might have white/red/yellow (RCA-type jacks, aka "phono") and that yellow jack is a composite video output. It would plug into the same color jack on the TV. There are also RGB (Red/Green/Blue) component outputs on many devices and similar inputs on the TV, so you have to match like color out to same color in and make sure the TV is set to composite video input, not HDMI nor component.
Also could just be a bad cable. It's always the cheap things that we overlook, so with the same output/input setup, assuming you match type, try a different cable. The actual color of the end on the cable does not matter, but don't plug a yellow-colored output jack to a red, white, blue or green input jack on the TV - that won't work.
If it has no internal sound, then you obviously can't make it function like a TV aside from the picture right? It does have inputs whether HDMI or standard Cable wiring to see TV from a cable box?
You'd need to have RCA cables coming from the cable box (Audio out - white wire I'd figure) going into a stereo near the monitor that has a VIDEO button on it where the white RCA cable is plugged into the Audio In jack.
A stereo receiver or even old sort of stereo with a Video or Auxillary sort of jack with button to activate that jack will allow for surround sound from the stereo coming from the cable box in sync with the video of the TV.
Optical carries only 5.1 sound, no video. HDMI carries both video and sound. If your receiver doesn't have HDMI, check your TV for optical output. You can go BluRay to TV via HDMI, then TV to receiver via optical.
If you don't have optical out on your tv, you're going to need either a receiver with HDMI or a BluRay player with component output (blue, green, red).
You're close. PHONO is NEVER the place to send Line Level signals. It is for the small output produced by a phono cartridge only. Google RIAA equalization to see why it sounds so bad when connected that way.
That you get sound through Phono at least proves your PC is producing an output. Now we have to figure out why your RECEIVER doesn't sense the program where it should be connected.
If you have another analog audio source that works on the receiver, temporarily connect the PC audio there to see how it sounds. Then think about why it doesn't work in MD/TAPE, SA-CD/CD, TV/SAT, DVD, or either Video IN. Any of those should work.
Your TV should also have a regular composite video input jack (yellow) in addition to the s-video input. Use that input instead of the s-video. The video won't be quite as clear as with s-video, but you have to work with what the combo gives you.
Looks like someone sold you a unit only partially working.
You may need to have the main board replaced, which is likely why the previous owner sold it.
My solution would be: Buy an inexpensive surround system and a VCR, Use the VCR as your tuner, and plug the audio output from the VCR into your surround system.
This way you will have a tuner (the VCR), and sound through the surround amplifier. You can also plug the audio output from your DVD player direct into the surround amplifier. This solution would likely run you less than half the cost of replacing the main board in the TV.
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.
