🔍 1. Lines on the Display

If you see vertical or horizontal lines running across your screen, this is usually a sign of a loose connection or a damaged screen panel.

🔧 2. Dim or Flickering Backlight

A dim or flickering screen means your LED backlight might be failing. This can worsen over time and may lead to complete darkness.

🚨 3. Ghost Images or Burn-In

If a faint image stays on the screen even after content changes, it might be "burn-in" or ghosting, which occurs due to prolonged display of static images.

❌ 4. No Display but Sound Works

If the screen is black but audio still works, your display panel or backlight inverter may have failed. This is a common issue we fix at Logic Technologies.

⚖️ 5. Color Distortion

Are colors looking strange or washed out? Faulty T-con boards or internal display damage can cause unnatural colors.
