Why does my 1080 p tv cut off. It will stay on for a minute and automatically cuts off. Under the lamp indicator is a red light showing.
Maybe bulb needs to be changed.
You need to make sure that it has been connected in the right way. Check that the connection is good and that the power supply is good. You can also disconnect it and connect it again so that it will be able to attach itself.
My 52 inch Samsung did this. Had to have a part replaced.
