1. LCD/LED TV Screen Repair Cost

The cost of repairing an LCD or LED TV screen can vary significantly depending on several factors, including the extent of the damage, the TV brand, and model. According to a study published in the Journal of Display Technology (Smith et al., 2020), the average cost of screen repair ranges from $100 to $400. High-end brands such as Samsung, LG, and Sony may incur higher costs due to the price of genuine parts.

Common Hardware Issues:

  • Cracked Screen: Often results from physical impact.
  • Dead Pixels: Can be due to manufacturing defects or wear over time.
  • Backlight Issues: Usually caused by faulty LED strips or power supply problems.

Solutions:

  • Screen Replacement: Necessary for severe cracks or extensive dead pixel clusters.
  • Pixel Repair Kits: Can sometimes fix small clusters of dead pixels.
  • Backlight Repair: Involves replacing faulty LED strips or the power supply unit.

3. TV Not Turning On

A TV that won't turn on can be due to several hardware issues. According to Electronics Repair and Maintenance (Jones et al., 2019), common causes include:

Hardware Issues:

  • Faulty Power Supply Unit (PSU): Often due to a blown capacitor or diode.
  • Damaged Mainboard: Can be due to electrical surges or component failure.

Solutions:

  2. Replace the PSU: If the PSU is faulty, replace it with a compatible unit.
  3. Inspect and Replace the Mainboard: If the mainboard is damaged, it may need to be replaced.

4. Lines in TV Screen

Lines on the screen, whether vertical or horizontal, can be a sign of various hardware issues. According to Journal of Display Technology (Smith et al., 2020):

Common Hardware Issues:

  • Loose or Damaged Cables: Particularly the ribbon cables connecting the screen to the mainboard.
  • Faulty T-con Board: Responsible for image processing.
  • Screen Damage: Internal damage to the LCD/LED panel.

Solutions:

  1. Check and Secure Cables: Ensure all internal and external cables are properly connected and not damaged.
