Sony offers to check 'smoking' TV models
Sony KDL-40V3000 TV Sony said a faulty component could cause some Bravia
models to overheat

Sony is to offer free safety checks on several of its TV models after a
number of sets started smoking.

The company warned that a component used in eight different versions of its
Bravia televisions may be faulty and could, in rare cases, overheat.

However, it stopped short of issuing a full recall.

Instead Sony said that anyone who was concerned could request an engineer
come to their home for free to inspect their TV.

The models affected are all LCDs, sold in Europe since June 2007.

They a KDL-40D3400, KDL-40D3500, KDL-40D3550, KDL-40D3660.

KDL-40V3000, KDL-40W3000, KDL-40X3000, KDL-40X3500.

Some 1.6 million of the TVs have been sold worldwide; 630,000 of them in
Europe.

Reports of overheating sets have so far all come from Japan.

The company said that the televisions were not at risk while they were
switched off.

It warned owners to be aware of any unusual noises, smells or smoking coming
from their Bravia.

Anyone noticing those symptoms should unplug the power cable and stop using
the set immediately, said a Sony statement.
