Is someone watchinge
Buy a Sanyo 65" 4K smart TV at walmart. Around $650. I havent had any problems with my Sanyo. Just an idea to fix your problems.
Did anyone find a fix to this? I am having the same problem with my UN60F6350 turning on and off the red light just constantly blinking and it's very annoying. I fear I am going to have to get a new tv but not sure I want to stick with Samsung now.
