A:Answer I like to just fiddle with settings any time I get a new device, so I'm not an expert by any means. I find that the Cinema (or movie mode, whatever it's called) seems to provide the richest sound across the board without completely drowning out the dialogue. Make sure that "Sports Mode" is turned off, as that takes over your whole TV (picture and audio).
When I am trying to calibrate a TV myself I load up something like Planet Earth on Netflix. I wait until it buffers up to 1080p resolution and start working on the picture first. Once I have the picture calibrated to my liking, I switch through all of the default audio presets to see if there are any that sound good enough to me before I start tinkering. I'm not sure why your equalizer would not be available, unless the TV thinks you are outputting to some external device.
