On the other way when the temperatures are low, the cables drastically contract due to changes in their temperatures making popping noise in the Lg television.

2. Starting the television

The main cause of popping noise in an Lg television is the starting process where the user is turning on the TV, and then the power cables receive power which warms them. After warming the power cables, the power cables try to stretch due to their expansion which causes the popping noise to occur.

3. Shutting down the television

After using the television, most people tend to put all the power cables and switches off at once which causes the cables to contract suddenly, causing the popping noise.  The popping noise can later damage the television parts due to sudden expansion and contraction of the cables as some may bend and fail to send power to the television when starting.

Therefore, it is good to shut down the television in stages by starting it by putting the television off first, and after some time, you shut down the power source, which gets the TV parts cool so that they are ready to rest.

4. Resting LG TV on uneven surfaces

When using the TV, some people place them on uneven surfaces so long as they watch what they want. However, placing the TV on such surfaces makes the TV be in a tilt position which increases the rate of popping noise when using the TV since most of its parts are not in their accurate positions.

It is advisable to use televisions on flat surfaces with rubber rather than on glass surfaces that are hard and can cause some other noises apart from the popping noise.
