I did not see a splitter like I had so not sure how your entertainment system is wired. My 36FK has composite wiring (3 wires vs component or HDMI) and had a splitter already installed to take one composite input (DVD player) and send it to all the TVs. In order to get satellite or DVD to all the TVs I had to add a switch to allow selection of DVD or satellite to go into the splitter.
DVD + satellite ---> switch ---> splitter
Else only the front TV could be hooked up to the satellite.
