Sharp has begun to roll out its 2012 line of LCD TVs. The new 6 Series is one of the lower-priced series, and it includes screen sizes of 52, 60, and 70 inches. We have not performed a hands-on review of the 70-inch LC-70LE640U, but here is an overview of its features. This 1080p LCD lacks the 3D capability, Quattron Quad Pixel Plus 2, and 240Hz technology that you'll find in the step-up 7/8/9 Series, but it does offer 120Hz technology to reduce motion blur and an edge LED lighting system, which allows for a cabinet depth of 3.5 inches and weight of 79.4 pounds. The LC-70LE640U does not include local dimming to more precisely adjust the LED zones to improve black level and contrast. The TV features built-in Wi-Fi and access to Sharp's newly redesigned SmartCentral Web platform, which includes Netflix, VUDU, Facebook, CinemaNow, YouTube, Twitter, and the AQUOS Advantage Live program that provides instant access to live customer support. A Web browser and DLNA media streaming are also available.

The connection panel includes four HDMI inputs, as well as one component video input, one PC input, and one RF input to access the internal ATSC and Clear-QAM tuners. All four HDMI ports are side-facing for easy access. Dual USB ports are available for media playback, and an Ethernet port is available for a wired network connection. The LC-70LE640U offers RS-232 for integration into an advanced control system.
The TV includes a solid assortment of picture adjustments, including: eight picture modes; an adjustable backlight and an automatic brightness sensor called OPC; five color-temp presets, plus RGB gain controls to fine-tune white balance; a six-point color management system; gamma adjustment; and digital noise reduction. The LC-70LE640U's 120Hz Fine Motion Enhanced technology has two options: 120Hz High and 120Hz Low, both of which add varying degrees of frame interpolation to produce smoother movement with film sources. The TV has four aspect-ratio options for SD content and four options for HD, with a Dot by Dot mode for viewing 1080i/1080p images with no overscan.
On the audio side, the setup menu lacks preset sound modes but offers treble, bass, and balance controls, as well generic surround, auto volume, bass enhancer, and clear voice functions. Finally, the Power Control menu includes power-saving settings to reduce power consumption, as well as an Audio Only option lets you turn off the video signal when you're only listening to an audio source.
