Some of the nation's biggest electronics firms are seeking fresh starts this spring under new presidents brought in to tackle the difficult task of re-establishing their slumping TV businesses in the competitive global market.

Sony Corp., now headed by Executive Deputy President Kazuo Hirai, who replaced Howard Stringer on Sunday, has already begun taking steps to turn around its ailing TV business, which is likely to post its eighth consecutive year in the red.

The company has terminated its joint venture with South Korea's Samsung Electronics Co. for producing liquid crystal displays for TVs and announced it will unload its noncore chemical business by the end of the year.
