Confusion between Sony 40EX710, Sony 40NX700 & LG LE7500

[Kittu]

Hi Jigar - Congrats on your purchase... Can you throw some light on Samsung's Panel Lottery issue... What is this and how will this affect me if I go for a Samsung...

I am confused between Sony 3D LED 40HX800 and Panasonic 3D Plasma P42GT20D... Why plasma??? Because of the "true black" PQ... Not sure how true and how black is true black!

Let me know... Await for your response...

HX800 has a deep black panel too... if you are looking for only black
