How to Troubleshoot an Overheating LCD TV
Plasma TVs consist of thousands of tiny pixel cells that allow gases to be heated with electricity to produce light. This process produces a sharper picture on the screen than was possible before the technology’s invention. In this article, you will learn how to troubleshoot an overheating LCD TV.
Overheating can permanently damage an LCD TV. The most obvious symptom of overheating is a sudden shut-down when the TV can no longer run properly. However, this problem can be easily fixed, requiring little more than some repositioning or cleaning.
Overheating can weaken the electronic components of LCD TVs screen. The Best Plasma TV says this can manifest in a condition known as screen burn-in. This is a permanent or temporary disfigurement of the plasma screen caused by the aging of some of the pixels.
However, heat-damaged pixels produce less light than other normally functioning pixels. You will notice a shadow or haze on the affected portions of the screen. The condition occurs when the screen is left on for an extended period which typically causes overheating.

A small ventilation slot is always installed inside all LCD TVs panels to keep air flowing and keep things cool. Make sure you keep these vents unobstructed and dust them regularly to improve air movement within the TV. Additionally, the dust can also get inside the panel and cause other problems inside the TV, making it doubly important to keep your vents dust-free.
After performing solution one and you’ve made sure your vent is well cleaned, the next step is to improve the overall airflow to your televisions panel. Tightly enclosed spaces trap heat, making it harder for your TV to properly dissipate heat even with clean vents.
If the vents are clear and airflow around your TV is good, but it’s still overheating, an external heat source may be the problem. If your TV is nearby a heating vent, close the vent. Move portable heaters elsewhere to reduce their impact on your TV’s overall temperature. If your TV spends a lot of time in direct sunlight, move it elsewhere.
