I have also the same problem with Samsung 32' F6100 series 3D LED TV. I is out of warranty only 20 days above warranty. When reported to the samsung The samsung engineer visited And says causual & by only visual inspection that there is problem in LED screen.
I question is is this really a problem of led screen or it is problem of the Driver IC. As i am a techinacal person , When led is damaged it should be black spot in that area , But there is no blackspot it is darker I think this should be Driver IC problem.
And also i have talk to the samsung Customer Care ,but i think there is no techincal person in the Team and solve my query . Please if anyone can Solve my problem . my question are as below
1) Is this really the Led Pannel Problem??
2) Genearally the led pannel life is define as 60,000 to 80,000 hours. But if i calculate that max 12 hours a day TV is ON then also it caome only 4000 hours in year. So what are the Derating FActor which has derate the led life So much. This is Big question Mark on the Quality & Customer service of Samsung Products??
