Problem Solution
The TV makes a noise as if something is dropping
inside.
This noise may occur when the plastic material inside the TV expands or
contracts according to the seasonal temperature or humidity. This is like the
noise from a furniture/cabinet/sink unit, and there is no need for concern.
