Stringer said Sony's consumer electronics business was holding up well, despite the U.S. slowdown, with Playstation 3 (PS3) sales improving.
Electronics operations account for nearly three quarters of Sony's total sales.
"PS3 has now gone past Xbox on the Christmas market. It's moving into its own as it gets into higher bandwidth ... PS3 is out of the woods and beginning to hold its own," he said.
The PS3 initially trailed rivals, due to the Sony machine's high price and an initial scarcity of strong software titles. But PS3 demand has shown some signs of picking up since the company cut prices and launched a new version.
