Turning on and running the TV will normally create heat in the components.
This heat expands the plastic parts that comprise the exterior.
At this time, different parts of the case expand and create friction against each other, possibly causing tapping or bumping noises.
This is called thermal expansion noise. -
To avoid thermal expansion noise, all parts of the product must be made of the same material so as not to generate friction when they expand.
However, it is almost impossible to make a sophisticated electronic product using a single material. -
This noise is also created in furniture, kitchen sinks, and cars and is not a defect.
The noise depends on the season and indoor temperatures, humidity, the years of use, the size of the product, etc, and often decreases over time.
※ Note that running a humidifier near the TV will increase ambient humidity and may aggravate such noises.
