How it's done

How We Perform Computer Monitor Repair

What our technicians do, what it requires, and how to tell you need it.

1 How It's Performed

For a repair job on this component, we open the display housing carefully to avoid stressing the hinge brackets, lift out the cracked or faulty panel, connect and test the replacement panel on the open chassis first, and only close everything back up once the picture is confirmed clean edge-to-edge.

Typical time: 30–45 minutes

2 What This Requires

  • A panel matched to your exact model's resolution, size, and connector pinout — a mismatched panel will power on but show no image.
  • Anti-static handling, since display cables and connectors are easily damaged by static discharge.
  • About 30–45 minutes of bench time once the correct panel is in hand.

3 When You Need This

  • The display works fine on an external monitor but not on the built-in screen — this usually rules out the graphics card and points to the panel or cable.
  • Pressure marks or ink-blot-like patches that spread over a few days.
  • A hinge that has been over-flexed, since that often damages the display cable running through it.
