QN95B 75" not turning on after idling overnight

[Montaser]

Hello.

I purchased this QN95B 75" TV from a friend who barely used it a couple of months ago. it's a great TV overall, but recently i am having this issue of turning on only after you unplug it from power. i have seen a few reporting the same problem, where their sets were replaced, however, i don't believe Samsung here will consider it a warranty fix since the TV was not from here originally. 

is it a one connect box fault? a cable or software issue? 

appreciate your answers

Hi @Montaser!

That's not what we like to hear! Could you tell us exactly what happens, when you plug the TV in, and then press the 'On' button on your remote control?

Everything works well in the TV except for when it is turned off for a long period (over nights) when i try turning it on the next day using the remote it won't work unless i unplug it from power. Although the red led was on. 

What i noticed is when i turn it off using the remote i don't hear this clicking relay sound.

Thanks for that, @Montaser. Have you ensured that your TV's software is fully up-to-date? If an update is available, please install this and let us know whether this resolves the issue:

The TV is up to date as no new updates are available
