Time: Thank you for purchasing the Samsung TU7000 TV and for your review. Watching TV for an extended period of time causes the panel to generate heat. The heat from the panel is dissipated through internal vents running along the top of the TV. The bottom, however, may feel hot to the touch after extended use. Children watching TV need constant adult supervision to prevent them from touching the TV. This heat, however, is not a defect and does not affect the TV's functionality. If your TV is flickering or dimming sporadically, you may need to disable some of the energy efficiency features. Disable Ambient Light Detection, Power Saving Mode, Motion Lighting, or Contrast Enhancer. Settings > General> Eco Solution> Ambient Light Detection Settings > General> Eco Solution> Power Saving Mode Settings > General> Eco Solution> Motion Lighting Settings > Picture > Expert Settings > Contrast Enhancer Run Picture Test. When the tested image quality is normal, check the signal of the connected device. Settings > Support > Device Care > Self Diagnosis > Picture Test I hope this helps.
