Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, the described symptom almost always point to an internal hardware issue; or more particularly, a low/missing/inconsistent secondary voltage and/or a failing board.Would you be comfortable working on the inside of the TV? ...live?Are you then considering a DIY (do-it-yourself) repair approach? If yes, you may need access to and familiarity with the use of a multimeter and even perhaps a soldering iron.
