Laptop LCD screens can be delicate and may need repair due to spills or drops. If the screen is the issue, it can be replaced with a few tools. If not, other parts may need to be fixed by a professional.
Laptop LCD screens are somewhat delicate and may require repair long before the laptop processor shuts down. Common problems are caused by drink spills or cracks that happen when the laptop is dropped, or sometimes the screen stops working for no apparent reason. Depending on the problem, an LCD screen can be repaired or, in cases where that’s not a viable option, the screen can easily be replaced.
Instructions for repairing a laptop LCD screen for a dropped laptop usually end with a complete replacement. However, this isn’t as bad as it sounds. It’s a short project that can be completed with nothing more than a replacement LCD screen and a few common tools. To make sure this is the best course of action, connect your laptop to an external monitor via the laptop’s VGA-out port. If the laptop starts up and the external monitor works, it means that the problem is only with the LCD screen and the internal components of the laptop are working properly. The easiest fix in this situation is to remove the broken LCD screen and replace it with the new screen.
To replace the entire screen, a small Phillips screwdriver and an Allen key are required. The battery and all power sources should be removed, then remove the cover exposing and removing the small screws around the screen surface. You may need to lift the lid off the screen with a flat object. Pay attention to how the wires are attached and where the connectors go, then remove the screws holding the LCD screen in place. Remove the old screen, replace it with the new one, then reverse the order to replace the screws, connectors, wires, and tape. Put the cover back on and it’s over!
To fix a laptop LCD screen on a laptop that didn’t work with the external monitor, you need to look into a few other areas. If the LCD screen is black, but a faded image was still visible on the laptop LCD, the inverter may be faulty. These can be purchased for under $100 US dollars and also easily replaced. If the problem isn’t the inverter, it could also be the backlight that’s the problem, and to fix a laptop LCD with a broken backlight, the entire LCD screen needs to be replaced as outlined above.
Were there wavy lines or a solid color screen on the external monitor display? If so, the problem is likely with the motherboard or video circuitry, and there are no instructions for repairing the LCD screen on a laptop with this problem. Your motherboard problem will need to be addressed by someone who knows how to fix such problems. The LCD screen will not function until this problem is addressed directly at the source.
