Heat problems
On September 4, 2008, Sony announced a worldwide voluntary product inspection and rework program for TZ-series notebook computers manufactured since June 2007. All model numbers beginning with VGN-TZ1 and VGN-TZ2 were eligible, along with some VGN-TZ3 notebooks. The issue involves "a limited number of units" which could potentially "generate heat around the DC jack inlet and frame of LCD screen, which creates the potential of deformation of the plastic casing". In the United States, the service offered is generally on-site, whilst in the rest of the world the service typically involves collection of the notebook by a courier, often DHL, for servicing in a Sony repair center. ChannelWeb reports 100,000 have been recalled.
