Electronics giant Sony has tumbled into the red, hit by falling prices for its televisions and DVD recorders.
Sony is due to unveil a restructuring plan in September
The Japanese group reported a net loss of 7.3bn yen ($65m; £37m) for the three months to June, compared with profits of 23.3bn yen last year.
Sony said it was also slashing its full-year profit forecast to 10bn yen, from a previous estimate of 80bn yen.
The loss followed poor earnings figures from Japanese peers Toshiba, NEC and Hitachi, who also reported losses.
Toshiba, the world's biggest manufacturer of microchips, reported a net loss of 8.9bn yen for the three months to June, while NEC reported a net loss of 10.9bn yen, on falling sales of chips used in mobile phones.
Meanwhile, Hitachi reported a net loss of 24.1bn yen in the quarter, from a net profit of 16bn yen a year earlier.
"Overall, our business condition is severe," said Hitachi's senior vice president and chief financial officer, Takashi Miyoshi. "We expect the price competition to get heated."
Matsushita Electrical Industrial - the maker of Panasonic products - and computer firm Fujitsu bucked the trend, reporting net profits of 33.4bn yen and 2.5bn yen respectively.
Matsushita said a recently introduced cost-cutting drive had enabled it to avoid the impact of falling prices.
Sony said it had also been hit by slowing sales for its market-leading PlayStation games console and reduced demand for image sensor chips used in digital cameras.
In March, Sony appointed UK-born Sir Howard Stringer - the former head of its US operations - as the first foreign group chairman in its 59-year history
The move came just a few weeks after Sony issued a profits warning for its vital electronics division.
