A blinking or flickering television can occur randomly. This dimming TV screen effect can seem like a strobe light and show flashes of black. A flickering TV that blinks can sometimes be fixed by simply turning the TV off and back on.
A component attached to the TV could be at fault. Cables may not be secure or a cable may be faulty. Check to see if your TV has an energy efficiency feature that can be causing the issue.
Disable some of its energy efficiency features such as the Eco Sensor or the Energy Saving feature to keep the brightness level consistent. (Applicable on Samsung TVs – FIX FLICKERING SAMSUNG TV)
