Heres a recommendation based on your needs:
Panasonic VIERA TC-L47E50
LCD panel with LED backlighting. 47 inches. $650. IPS for color accuracy and viewing angles.
LG LM7600 or LM6700
LCD panel with LED backlighting. 47 inches. $700-1200 (they both go on sale regularly). Very good TVs. A little bit over your budget for the 7600, though.
Sony HX820 or HX850
LCD panels with LED backlighting, 46 inches. $900-1600 (they go on sale sometimes). Extremely good picture quality for the price and excellent color accuracy. Over your budget unless you find a good deal.
LCD panel with LED backlighting. 47 inches, also comes in 42. Slim bezel design that is cheaper than LG's offerings, the 47'' is $800 on Amazon. Unsure of picture quality or color accuracy. You could also look into the L5200U, much cheaper but a much thicker bezel.
