Not all will let you change inputs or pull up the on screen menu which is my next test.
Had my TV since 2013 to 2018. No Major Problums beside the voice command comes on by its self every so often, into yesterday my 55-inch Samsung 3d Smart TV went black/dark blue as my kid were playing there game. Audio works. When TV is on I can see light on but no picture/video. Lost remote control years ago. Modele No. UN55F8000BF
