trying to hook up an lg blu ray dvd home theater to samsung tv with cable box

Solution
Cable box connect to the TV with HDMI.
BD/HTS connects to the TV with HDMI for playback. Use the HDMI-ARC input on the TV (there will only be one)
If the TV and BD/HTS both have HDMI-ARC then the same HDMI cable will get audio from the TV to the HTS for playback.
If they don't both have ARC then you will need to connect the TV optical audio output to the HTS. Check the TV manual on how to turn on and configure either ARC or the optical output.
