(Reuters) - Sony Corp named Vice President Kazuo Hirai as president and CEO, replacing Howard Stringer who will step down from day-to-day management in a long-expected change for a company struggling to regain its driving force in consumer electronics.

Stringer will remain chairman of the company until June, when he will become chairman of the board of directors, a separate post that will not be directly involved in company management, Sony spokeswoman Mami Imada said. The are no plans to replace him in the chairman's role, she added.

Sony announced the changes ahead of its earnings report on Thursday, which is expected to forecast the company will post a net loss for the fourth year in a row as its TV division bleeds red ink. Hirai will take over on April 1.

The last year has been brutal for many Japanese companies, hit by a strong yen that hurt exports, and two natural disasters -- the March earthquake in Japan and record floods in Thailand.

But Sony has also come under fire for losing the innovative edge behind products like the Walkman and the Playstation, and ceding ground to rivals such as Apple Inc and Samsung Electronics as consumers snapped up their iPhones, iPods and Galaxy gadgets.

The urbane and English-speaking Hirai, 51, will have to plot a course to revitalize the electronics giant as consumers lose interest in its products and gravitate instead towards smartphones and tablet PCs from other brand names.

Sony's shares have lost nearly two-thirds of their value since Welsh-born Stringer, who turns 70 later this month, took the helm as CEO in 2005.

In contrast, Apple shares have galloped ahead more than 1,000 percent, while Samsung, a maker of smartphones, flat panels and computer chips, is up more than 100 percent over the same period.


Hirai was effectively anointed as Stringer's successor last March when he was promoted to head Sony's consumer products and services businesses, which produce the bulk of Sony's $85 billion in annual sales.

He made his name in the PlayStation video games division, once a key profit driver for Sony that fell into the red for four consecutive years until he took the reins and pulled it back into the black two years ago.

The path we must take is clear, he said in a statement on Wednesday.

To drive the growth of our core electronics businesses -- primarily digital imaging, smart mobile and games; to turn around the television business; and to accelerate the innovation that enables us to create new business domains.

Stringer, a former journalist who later ran U.S. broadcaster CBS, was brought in as a rare foreign CEO at a top Japanese company to shake things up and restore its innovative edge in consumer electronics. Many analysts though see his major achievement as cost cutting.

Stringer's restructuring efforts included selling off TV factories in Spain, Slovakia and Mexico and outsourcing more than half of its production to other companies, including Hon Hai Precision Industry, the contract electronics maker that also counts Apple as its key customer.

In recent months, Sony exited an LCD panel joint venture with Samsung, which will allow it to procure screens for its TVs more cheaply.

It also agreed to buy out Ericsson's half of their smartphone venture for $1.5 billion to shore up its position in a market where Apple and Samsung have become leaders.

Sony's share of the flat-panel television market has been eroded by the rise of Samsung and a host of nimbler Asian players, while a hacking scandal last year undermined confidence in its management.

Many of Japan's other electronics titans have also stumbled in recent years. In the current reporting season, Nintendo and Sharp Corp both issued bigger-than-expected loss projections for the full year.

South Korean rivals such as Samsung have been particularly aggressive in investment and blessed with favorable currency movements, while Apple has stolen much of the innovative thunder that once emanated from Japan.

Sony reports third-quarter earnings on Thursday, when it is also due to brief the media on the management reshuffle.

Analysts polled by Thomson Reuters I/B/E/S gave a consensus forecast of just 8.8 billion yen ($115.41 million) in operating profit for the key October-December quarter, when consumers spend heavily on gadgets for year-end gift-giving, and 8.2 billion yen for the full financial year to March.
