SAMSUNG UE55NU7170U The TV turns on and off. every 10 seconds no picture on the screen

try to cover the lines more. or with few lines. either above or below the ribbon. or if the TV has two ribbons. try another ribbon to cover the lines. if you have a picture that is not clean, cover more lines or less or spread the coverage of the lines above or below the ribbon,,,
it depends on the defect of the screen, there are TVs that require more lines to cover, there are TVs that require fewer lines to cover, you must try to be successful. even if you don't cover the lines correctly, nothing happens. the only way is to try
