If your tv has an audio out, then you will need to get an RCA to 1/8 inch cord, so you can plug it into the Big Jambox. I have audio out coming out of my Blu-ray player so when we watch movies i have extra sound coming from the Jambox and it is great.
I use my Jawbone in my car, and it gets moved around in the front passenger seat. I also keep my other equipment and clipboards in the same front seat. It's not unusual to bump my cables with my clipboards or to press the end of the jambone against the seat. A 90 degree input plug will not be damaged by pressing against it with my clipboards or the edge of the seat. I had used a straight plug and the wire was bumped enough to finally short out. I no longer worry about that.
If your TV has bluetooth capability, it will work. Or use the 1/8 th inch cable. Note: I recommend a cable with a 90 degree bend on both ends to avoid damage to your cable when bumping it against objects.
