Chosen Solution

Hello , My Samsung tv (PN51D6500DF ) keeps cycling ON and OFF. When I turn it ON, it goes till ‘Smart TV’ boot up sequence, then it blinks quickly and then couple seconds later, turns OFF. From the start till turning off the LED upfront blinks 5 times. Thanks for the help

@Viraj and @tiiguy all of this sounds more like a bad processor on the main board. Of course you have unplugged your TV, disconnected every input source and then held the power button down to discharge the capacitors. Then restarted it with only one video input source and tried all other sources as well. If so, I am pretty confident that the issue is your main board. Also, make sure that you try different cables.
