You will need a couple things based on what other electronics you want to hook up. For instance if you have a cable or satelite box to hook up outside of what you listed above. The TV you listed will only have 2 HDMI inputs. If you have HD cable/satelite you will need an HDMI cable running from that box to an HDMI intput in the back of the TV. The same is true with the Blue Ray player. This covers the two inputs on the new TV. Hopefully you will have a optical audio output on this TV, I do not see it listed either way on Best Buy's website. If you do it will be a small black square type connection on the back of your TV, probably near the HDMI inputs. You can tell its an optical output because when the TV is plugged it a red light will be eminating from an optical output. Also it should be listed as Optical Out or something along those lines. You connent the optical cord you have or an upgraded one you purchase from the back of your TV to the back of the soundbar. This is what will send the audio signal from everything going into your TV out to the soundbar.
