I need help , hooking up my samsung HT-Z410 HOME THEATER, TO MY LG HDTV, SO THAT WHEN I'M WATCHING REGULAR TV THE SOUND OF THE TV CAN COME OUT TRUE THE HOME THEATER SPEAKERS, CAN IT BE DONE? CAN A COMCAST TRANSPORT ADAPTER BE CONNECT IT TO THE SAMSUNG HT-Z410 HOME THEATER? CAN SOME ONE HELP ME PLEASE.

First of all here is a link to the manual....http://downloadcenter.samsung.com/content/UM/200802/20080220095448484_HT-Z410-XAA.pdf and yes it can be conected thru your comcast but you wil need to buy probably cheapest at wallmart an RF Modulator (Less than 20 dollars) and from your cable box (vidieo out, or to tv) install the cable to the rf mod unit (ant in) and that converts it from coaxial cable to rca (meaning a cord with yellow ,red,white push on connectors) plug the red and white into aux input on surround system (see #3 on manual view on backside of surround unit)and and you got it.It your tv does not have a yellow vidieo connection (which is where the the yellow plug into tv)in the back then add a coaxial splitter after the comcast box so that the 1 coax line goes to tv and the other coax goes to the rf mod then thru RCA cables to the surround sound.you may need to buy xtra cables but they are cheap. hope i helped........you may try asking family or friends for the above equipment i described.the newer tv's dont need it and many people have this stuff layen around...good look
