Absolutely! My TV was still under original warranty. Technicians came three times unable to witness the event. After much complaining and posting all of my live chats online, Samsung, finally replaced my TV with a brand new model!
Thanks for the reply back I had another technician come out he did not witness the flashes gave him a short video clip called me back a few hours later and said Samsung is aware of issue. And because my TV is out of Warranty Samsung would not replace. So I'm going wait till around August to see if anything is done with software update if not will buy new TV from Sony or LG. Been in contact with a Samsung engineer via email and also told me Samsung is aware of the issue overseas.
