The first couple of hours can produce a slight smell as components heat up and are used the first time. However, if this is ongoing, or more than just a few hours, I would suggest having the unit exchanged or serviced.
We cover it for a year, so if you want to get it serviced, you can call 800-SAMSUNG. Otherwise, you could likely exchange it, depending on how brand new it is.
Any lengthy odor should be investigated by a technician.
Keep me posted.
Love this brand new tv. I notice however after turning it on and letting it run for awhile there is an electronics type smell in the living room were it is. I only notice it when i leave the room and then come back into it. At first I thought it may be overheating. But it has been running for serveral hours now and works fine. Any hints as to whether this ssmell is normal?
