Sony has reported a loss for a fourth consecutive quarter, due to slow sales of slow mobile handsets.
The company had an operating loss of 32.6 billion yen ($US357.5 million) in the three months to September, from a profit of 11.05 billion yen a year earlier.
However it has now cut its operating loss forecast to 60 billion yen from 110 billion yen for the year ending March 2010.
The BBC reports Sony recently cut the sales price of its PlayStation 3 games console.
Meanwhile, Panasonic and Toshiba both reported quarterly profits.
Operating profit at Panasonic, the world's largest plasma TV maker, was 49.1 billion yen in the three months to September, against 118.6 billion yen a year earlier. The company posted a 72.9 billion yen profit last year.
Toshiba said its microchip operations produced an operating profit of 5.2 billion yen in the three months to September, up from a loss of 29.3 billion yen the previous year.
