Why does my LG 75US340C2UD turn off suddenly?

What to do if my LG 75US340C2UD LED TV has no image and no sound?

What to do if my LG LED TV is not detecting HDMI signal from PC?

Why is my LG 75US340C2UD making cracking or buzzing sounds?
The cracking noise you hear when watching or turning off your LG LED TV is typically due to the plastic thermal contraction caused by changes in temperature and humidity.

Also, a low-level noise might come from a high-speed switching circuit supplying a large amount of current; this does not affect the TV's performance or reliability.
