Solved! Samsung TV Rebooting by itself

[aritra.chandra]

I have a Samsung UN465300FXZA TV that keeps rebooting by itself when turned on. It only displays the samsung smart TV logo and then restarts. I have tried resetting the TV from menu option when I was able to turn it on the last time. How do i know if it is a problem with the Main board or the Power Supply.

Question from aritra.chandra : "Samsung UN46EH5300FXZA TV rebooting problem"

I have a Samsung UN46EH5300FXZA TV that keeps rebooting everytime i switch it on at interval of 4 to 5 seconds. TV doesn't turn on. Only displays the initial Samsung Smart TV logo for a second and restarts by itself. How do i know if it is a problem with the power supply board or main board?

They sell replacement boards and are very helpful.
I will guess that it's not the power supply board but ask them.
