You won't read it anyway, but I'll explain it to you for the 5th or 6th time:
You don't "turn off the LFE" in these bass-managed TV-surround sets, you're turning off the sub-woofer. Like pointed out before, that's not the same.
It's almost certain that the sub-woofer will also carry the LFE-signal, but without checking the raw audio data you won't know what really went into this channel.
I mixed several dozens of huge music productions in surround, some of them became award-winning, multi-platinum selling products. They were mastered in the most esteemed mastering houses in Europe, where no-one ever complained. I can tell you that apart from a little "woop woop" from a bass-drum (just for the sake of it) there was no signal in the LFE channel whatsoever.
