And yes. There are many LCD TVs that do that. This does not tell you what is broken. It only tells us to get it fixed if we don't know how.
My Samsung 40EH5000 when turned on (with or without remote) after approx two minutes turns off then with a delay of approx two seconds turns itself on. This is repeated constantly, has anyone ever had this problem? I checked the sleep timers etc and all is correctly turned off
