I noticed a discoloration in the panel of a brand new Samsung UA-40F6300. It is only noticeable at night when the lights are out, and when the display is showing something that's not totally black, say 1% black. There are areas where the LED is brighter than it's supposed to be.
I noticed the same issue with my other Samsung gadgets, particularly with my first Galaxy S3, which also had a yellowish tint. My second Galaxy S3 did not have this problem. The Galaxy S2 also had similar issues.
Anyone else have this problem? I'm deciding if I should send this for a replacement. The last time I went to have my Galaxy S3 screen replaced the technician just pretended that it was "normal". I'm worried I'll be wasting my time again getting this replaced, since it is impossible to simulate during the day where there's ambient lighting present.
