Why Do TV Screens Break?
TV screens can develop various issues that render them useless or impair their display quality. Some common culprits include:
- Physical Damage: Accidents happen, and a TV can easily get cracked or shattered due to falls, impacts, or improper handling.
- Backlight Failure: The backlight illuminates the TV screen, and if it fails, the screen will appear dark or dim.
- Power Surge: Power fluctuations can damage the TV’s circuitry, affecting the screen’s functionality.
- Software Glitch: Occasionally, a software issue can interfere with the TV’s display, causing it to freeze, show glitches, or behave erratically.
- Aging and Wear: Over time, TV screens can experience degradation due to constant use, heat, and exposure to environmental factors.

Before you start tackling your TV’s screen issues, gather the necessary tools and materials:

Step-by-Step Guide to Fixing a TV Screen
