Laptop Screen Troubleshooting and Repair

A broken or malfunctioning screen can be one of the most common hardware problems when talking about laptop repair. Sometimes, the immediate cause of the problem is apparent when the laptop screen has cracked or broken due to physical trauma. Other times, the source of the problem is not so obvious. This article we’ll introduce you the troubleshooting steps before the replacement work, as some type of the problems may not due to the screen itself.

Pixel Problems -- Pixels often get damaged, making the laptop screen very difficult to read and use. Laptops use LCD (liquid crystal display) to show images, which are made from thousands of pixels (little dots). If a few pixels in one area are damaged, this can ruin the entire computing experience. In most cases, it is best to remove the entire laptop screen and replace it with a new one.

Faint Images — The backlight is a major component of the laptop screen, however, sometimes the backlight does not work, making the screen extremely difficult to read. The problem might be as simple as one of the latches being stuck in the closed position. For instance, if the laptop is opened and the switch is stuck in the closed position, the computer is usually on, but the backlight remains off. First, find the backlight switch. These switches are usually very tiny and located near the laptop hinges. Try to open and close the laptop a few times, if this does not work, a gentle tap or using a small pin to try to gently un-stick the latch usually does the trick.

Screen Flickers or with a Solid White Color — If the laptop screen flickers on and off, the cause is probably an inverter problem. The inverter supplies power to the screen’s backlight. Inverters are easy to replace and usually cost about $100. If the laptop screen is a solid white color, then the problem is possibly a bad cable connection between the monitor and the system board. Open up the laptop and make sure that the cables and connections are set correctly and undamaged.

Jumbled Screen Images -- Laptop users often see jumbled images on their screen. In most cases, this is not due to the screen itself, but possibly the video card. One quick way to determine what is causing the screen to be jumbled is to connect a monitor to the laptop with a VGA port. If the other monitor shows jumbled images, then the problem is probably the laptop’s video card.
