Here’s a list of reasons why flickering may appear on a Samsung TV:

  • Power Cable Problem.
    Inconsistent power supply causes Samsung TV to flash on and off. 
  • Overheating.
    Samsung TVs can overheat due to blocked and dirty air vents, resulting in unexpected flickering. Overheating also leads to internal damage, especially on the TV’s LED.
  • TV Glitch.
    Your Samsung might have bugs or software glitches, making it turn off and on repeatedly. 
  • Faulty Picture Settings.
    Incorrect picture settings such as low resolution and contrast can cause your Samsung TV to flicker on and off. For instance, a contrast that is too low can cause pictures on your TV to look dark. This makes the TV look flickering when it displays dark images.
