On your remote for the TV. There is a button that looks like a plug below the scroll wheel push it and it will show you a list of things on the side. HDMI 1 should be selected . If not that is what is happening, Select it and the push return button(Back) Someone could have selected something else buy accident. Before you try this make sure the TV is on and also if you are hooked up to a cable box. Make sure it is on as well.
Sorry, there was a problem. Please try again later.The cable may be bad . Try resetting or new cable.. if the light is flsshing it doesnt sense s signal and may go right into sleep mode
