Repairing a computer screen: guide and solutions for damaged screens

The computer screen is at the heart of our digital interaction, but it can be subject to a variety of problems that compromise its smooth operation. Whether you're using a laptop or a desktop computer, these failures sometimes require technical intervention to restore your device's performance and aesthetics.

Common screen problems and solutions

All computers, whatever their brand, can experience display problems. Among the most common problems are :

• Cracks or breaks due to impact.
• Slab malfunctions, often beyond repair.
• Graphic card or internal connection failures.

In some cases, simply connecting the computer to an external display can confirm whether the problem is with the screen or another component. If the display works correctly on the external monitor, it may be necessary to replace the panel.

Replacing a laptop screen

When repair is impossible, replacing the panel is often the best option. Here are the main steps:

• Switch off and unplug the device: Make sure the computer is completely powered down to avoid any electrical hazard.
• Remove the battery (if possible): This is essential for safe working.
• Dismantle the screen frame: Using suitable tools, carefully remove the plastic or rubber edges.
• Unscrew and remove the damaged panel: Remove the fixing screws and disconnect the cables carefully.
• Install the new panel: Connect the new panel, making sure to secure the cables, then replace the screws and frame.
• Test the screen: Switch on the computer to check that the new panel is working properly.

This operation can be carried out at home if you're comfortable with computer equipment. If not, we recommend you call in a professional.

Estimated costs

The cost of repair or replacement depends on a number of factors:

• Computer make and model.
• Availability of spare parts.

Safeguarding your data and securing the intervention

A damaged computer screen can often be repaired or replaced to restore optimal use. Whether it's a fixed screen or a laptop, there are a number of ways to solve the problem, from initial diagnosis to complete replacement of the screen.
