Jeff, you will not need a One Connect Cable on the TU8000 as it is not supported on this model. The TV comes with a power cable - if you need any additional cables (HDMI/Optical) to connect external devices, check out some options here: https://www.bestbuy.com/site/searchpage.jsp?_dyncharset=UTF-8&id=pcat17071&iht=y&keys=keys&ks=960&list=n&qp=cabletype_facet%3DCable%20Type~HDMI%5Econnectortype_facet%3DConnector%20Type~HDMI%20Type%20A&sc=Global&st=cables&type=page&usc=All%20Categories ^Gina
