BenQ is a Taiwanese multinational company that manufactures a wide range of electronics, including LCD monitors. These monitors are sleek, modern, and high-tech, offering a competitive alternative to major brands. While BenQ monitors are generally reliable, certain issues may arise, such as problems with the backlight lamp, screen, or inverter, that necessitate disassembly and repair. This guide will provide a comprehensive overview of the steps involved in disassembling a BenQ LCD monitor, empowering users to troubleshoot and resolve issues independently. By following these detailed instructions, individuals can confidently take apart their BenQ LCD monitor, perform necessary repairs, and potentially save on labour costs.

Power off the monitor and unplug the AC power adapter cord

To disassemble a BenQ LCD monitor, the first step is to power off the monitor and unplug the AC power adapter cord. This is a crucial safety measure to ensure that you don't risk electric shock while working on the monitor. It also prevents any potential damage to the monitor's internal components. Once the monitor is powered off, you can proceed to unplug any other cables connecting it to your computer.

It is important to take precautions when working with electronic devices. Before beginning the disassembly process, ensure you have a clear and well-lit workspace. Gather the necessary tools, such as a Phillips-head screwdriver, and lay out a large, soft towel on your work surface to protect the monitor's screen from scratches or damage. Place the monitor on the towel with the LCD screen facing down.

By powering off the monitor and unplugging the AC power adapter cord, you are not only ensuring your safety but also preparing the monitor for the subsequent steps of the disassembly process. It is important to follow the correct sequence when disassembling any electronic device, as skipping steps or rushing through can lead to damage to sensitive components or, worse, injury.

Taking the time to properly power off the monitor and unplug all necessary cables demonstrates a methodical approach to the task at hand. It also showcases your understanding of the importance of safety and caution when working with electronic devices. This step-by-step approach will help ensure a smooth and successful disassembly process, allowing you to identify and address any issues within the monitor.

Remove the screws holding the base

To remove the screws holding the base of your BenQ LCD monitor, you will need a Phillips screwdriver. Before you begin, make sure you have unplugged your monitor and placed it face down on a soft towel on a sturdy, flat surface. This will prevent damage to the screen.

With your Phillips screwdriver, locate the screws that secure the base to the bottom of the monitor. There should be two or three screws that need to be removed. Once you have removed these screws, set them aside in a safe place so that you can easily access them when it's time to reassemble your monitor.

Now, gently remove the base from the monitor. On some models, you may need to detach the stand base by pushing down on a plastic locking clip where the base meets the monitor while simultaneously pulling the stand down and out.

With the base removed, you can now access the rear of the monitor and begin the next steps of disassembling your BenQ LCD monitor. Remember to keep your screws and other components organized to make reassembly easier.

Detach the monitor stand

To detach the monitor stand of your BenQ LCD monitor, start by turning off the monitor and unplugging all cables connecting it to your computer. This is important for safety and to avoid any damage to the electrical components. Place the monitor on a table or workbench with the LCD screen facing upwards to prevent any damage to the screen.

Now, you need to remove the monitor stand. This can be done by locating the plastic locking clip where the base meets the monitor. Push down on this clip while simultaneously pulling the stand downwards and outwards to detach it from the monitor. This may require some force, but be careful not to damage any other components.

Once the stand is removed, you will expose the screws that secure the base to the bottom of the monitor. Use a Phillips-head screwdriver to remove these screws. There should be two or three screws securing the base. Once they are removed, set the base aside.

With the base removed, you can now access the rear of the monitor, where you will find the rubber grommets on the outer edges of the rear screen bezel. These need to be removed gently with an awl or scribe to access the screws securing the front and rear bezel pieces. Be careful not to lose these small grommets as you will need them when reassembling the monitor.

Remove the screws on the back cover of the screen

To remove the screws on the back cover of the screen of your BenQ LCD monitor, you will need a Phillips-head screwdriver.

First, lay the monitor down on a table with the LCD screen facing up to prevent damage to the screen. Next, remove the screws holding the base. You can do this by pushing down on the plastic locking clip where the base meets the monitor while simultaneously pulling the stand down and out. Once the base is removed, set it aside.

Now, you can remove the screws holding the back cover of the screen. Start by prying out the back cover using a screwdriver in the holes at the bottom. Continue along the bottom edge, then follow the side edges all the way to the top.

Disconnect the control panel and VGA connector screws

To disconnect the control panel and VGA connector screws, you will need to have already laid your BenQ monitor face down on a soft towel on a sturdy, flat surface, such as a desk or table. This is to prevent damage to the screen. Ensure that the monitor is powered off and the AC power adapter cord is unplugged.

Now, you need to locate the VGA connector screws. These are usually not too hard to unscrew, but you will need a 5mm wrench or pliers. If you use pliers, be careful not to damage the connector. Once you have located these, simply unscrew them.

Next, you can disconnect the control panel. To do this, you will need to use a screwdriver to pry out the back cover. Start at the bottom, where there are holes for your screwdriver, and continue along the bottom edge and up the side edges to the top.

Once the back cover is removed, you can slide back the logic board cover. You do not need to remove the tinfoil sticker. Now, you have access to the logic board and can proceed as required.
