Theres no volume control in the BLT1.
That means all the inputs on BLT1, has be volume regulated by something else then the BLT1.
The BLT 1 has:
-PowerLink Inputs.
-Optical input.
-Stereo RCA line input.
If the Sony tv has a volume regulated optical output you could use that, but since it probably doesn't (I have never seen a Sony TV with that spec.).
You need to have a stereo (preout/Headphone) analog output. that can be connected to the BLT 1's Stereo RCA line input..
Copy/paste from sony user guide (model X900):
Connect with an audio cable or headphones. You can listen to TV sound through
your stereo system or headphones.
To set the sound output for headphones or an external audio system, press the
HOME button, then select [Settings] → [Sound] → [Headphone/Audio Out].
When you set [Audio Out] in [Headphone/Audio Out], select [Fixed] or
[Variable], press the HOME button, then select [Settings] → [Sound] →
[Audio Out].
Bang & Olufsen have created this fantastic guide for the BLT 1: http://www.bang-olufsen.com/interactive-guide/
The answer: Yes you can connect BLT 1 with a 3rd party TV if it has a headphone output (volume regulated stereo output), without a receiver, preamp or surround sound processor.
But if you have an idea about surround sound with the BLT1, I would suggest you buy a BeoSystem 4 (4600USD) or a 3rd party surround sound processor (price 1000USD).
