The picture will come on when you first turn it on but after 15 minutes or so it fades away. The sound still comes out but no picture. Sometimes it will come back on on its own after a while and then go out again. If you turn it back off for 15 minutes or so it usually comes back on. We already bought a new tv and that one works fine so its not the cable box but I would like to put the old tv in my room.
