A staff of Japan's electronics giant Sony shows the new line up of television sets. Sony said that some 1.6 million of its Bravia flat panel televisions were at risk of overheating due to defective parts, but the electronics giant did not issue a recall.

Japan's Sony said Wednesday that some 1.6 million of its Bravia flat panel televisions were at risk of overheating due to defective parts, but the electronics giant did not issue a recall.

The company said it would exchange a defective part in about 189,000 of the televisions which were sold domestically since September 2007.

Sony has so far received about a dozen complaints from customers in Japan whose televisions partly melted due to overheating, but it said there were no reported injuries.

A total of 1.6 million Bravia displays equipped with the same defective parts were sold worldwide, a company spokesman said, adding that Sony may take similar measures to repair units sold overseas.
