SMG - TV Makes a Cracking or Popping Sound

Hearing cracking or popping noises after you turn off the TV can be alarming. However, these are completely harmless and will not affect the TV. Here are a few tips to help reduce this from happening.

TVs use a combination of metal and plastic material. These materials are subject to expansion and contraction due to temperature changes. With expansion or contraction, occasional creaking, popping, or cracking may be heard. With this in mind, here are a few quick tips on how to reduce expansion which causes these noises.

• Ensure that there is adequate ventilation. Some enclosures may not allow for proper ventilation. This causes the internal temperature to increase and the plastic to expand even more than normal. For recommended ventilation requirements, please see the user's manual.
• Make sure there aren't any heating or air conditioning vents pointing directly at the TV.
• Verify that the TV is on a flat and level surface. Tilting or an uneven stand can increase these noises.
