So basically when I turn my Samsung tv on it makes a loud noise that turns off and on then does that again for a while...

I have a chormebook the same as the one in the picture not mine, I have a chormebook i use and i go to youtube to watch...

Press and hold the Power button and Volume Down (-) buttons on the TV (not the remote), and while holding the buttons, plug the power cord back in. Continue to hold the buttons down until a green LED light appears near the Sony logo on the TV front. Honestly i read your problem and i copy pasted to google this is what i found.
