Just bought a KDL 50R550A LED LCD flat screen TV. It had a chemical odor out of the box. It is of course worse when the Sony is turned on, and fills the room with a perceptible taint (and has now for days without apparent dimishment). The Sony runs VERY COOL (not even warm air felt at the vents), but the off gassing is there nonetheless.
Others have commented on the net, on these smells with various brands of TV's. Many have tried to dismiss these emissions as either belonging to a defective item (not normal), or as short lived (as disappearing after a few hours or at most a day or two of new product burn in). I dispute those suggestions. My parents had a Samsung that is still off-gassing with the same chemical smell that my new Sony is, after TWO years. And others have tried to 'burn off' the smell, over periods of weeks, and months, sometimes with a perceptible diminishment (but NEVER entirely), but OFTEN not. Understand that governments and industry do a POOR JOB of testing health-wise for the many new chemicals that industry creates each year (even single chemical testing, and never in combination as they appear in human blood).
I am interested in generating some discussion of this, and awareness of this with this thread. To say to U all, that things are probably NOT OK, and urge U consumers to give some thought to these things, and encourage U to fill discussion boards with your concerns. Sony and others care ONLY about sales and the bottom line. If U DO NOT EXPRESS Concern then your kids will continue to be a testing ground for new chemicals (and kids cancer rates are going UP, not DOWN).
We are taking our Sony back (I have NO confidence that the smell will be gone before our 30 day return period), and will try a Panasonic next (based on a recommendation from a lady that had the same trouble with a Samsung model).
