Sony, Japan's once-mighty electronics maker, has lost billions of dollars from TVs but Sony won't quit. Sony's restructuring plan is focused on gaming and image sensors, but TVs remain among their best-known products. As part of the company's 2015 4K Ultra HDTV lineup, which includes six new series, Sony Electronics has announced pricing and availability for the X900C and X910C series 4K Ultra HD TVs.

Pre-sales on the X900C begin Sunday, June 21, 2015, with full purchase availability beginning July 2015. The X910C will be available this summer:

• X900C 4K Ultra HD TV – [$2,499, $3,999] 55" class (54.6" diag) , 65" class (64.5" diag)
• X910C 4K Ultra HD TV – [$5,499] 75" class (74.5" diag)

The X900C combines 4K clarity with a very thin design. At just under 0.2 inches thin, the X900C model is thinner than a smartphone and is Sony's thinnest TV yet.

Powered by the X1 processor engine, the X900C and X910C feature maximized contrast, color and clarity in both HD and 4K content. The X-Reality PRO Picture Engine upscales all existing HD content to 4K quality, and colors come alive on the screen thanks to TRILUMINOS display technology.

Lastly, the X900C and X910C are powered by Android TV. It allows users to access content from apps like Netflix, Amazon Instant Video, YouTube, Hulu, CBS News, CBS Sports, Crackle, NBA Game Time, Pandora and SlingTV and over 600 other apps or access a selection of games and additional content from the Google Play store right on the TV. With Google Cast, users can cast their entertainment apps such as HBO GO from their Android or iOS device, Mac or Windows computer or Chromebook to the TV. The TV also supports a voice search feature.

This summer, gamers can also bring the world of PlayStation direct to the TV with PlayStation Now. PlayStation 3 games can be streamed to the TV and played with a DUALSHOCK 4 controller.

Staying in the TV market - particularly at the premium end - ensures the brand and quality are at the forefront when consumers shop for other electronics. Sony says it has seen a strong correlation between sales trends for its TVs and audio systems.
