Nothing ends a fun evening faster than your television overheating and melting.

Sony said today that about 1.6 million of its Bravia flat panel televisions are at risk of overheating due to defective parts, reported AFP. The Japanese electronics giant has not, however, issued a full recall of the affected TVs.

Approximately 189,000 of the potentially defective televisions have been sold in the U.S. Sony says it plans to exchange the defective part – a faulty component in the backlight system – in the televisions for homeowners who have purchased one since September of 2007.

Sony became aware of the problem when several dozen Bravia customers in Japan reported that their televisions overheated and partly melted as a result. There have been no reports of injuries, however, and the problem has not been reported outside of Japan. 

Sony estimates that a total of 1.6 million Bravia liquid crystal displays that contain the defective parts were sold worldwide, said a company spokesperson. The company plans to address the the defective part in all of them.

The recalled Bravia units will be repaired if the component in question is found to be faulty. Sony plans to dispatch a service crew to inspect any sets that might be affected, said the Sony spokesperson. The company may offer a rental TV while repairs are being made, but it will not issue refunds or replacement televisions. 

This is not the first defective part problem associated with the Sony Bravia. In April 2010, a fault was found with the Bravia's stands. Sony offered repairs – in the form of a replacement screw – because many of the stands were found to be too weak to support the TV in some cases, reported BusinessWeek.
