Disassembling the monitor

To repair your ASUS LCD monitor buttons, you will need to disassemble the monitor to access its internal components. Here is a detailed guide on how to do this:

Before beginning the disassembly process, ensure you have laid the monitor face down on a smooth, clean surface. This will protect the screen from accidental damage.

Now, let's begin by removing the four rubber covers that hide the screws at the rear of the monitor. Use a stiff, pointed tool, such as a metal spudger, to carefully pry out these plastic covers. Once removed, you will expose four screws.

Proceed to remove the screws that secure the monitor stand to the display. The specific size of these screws may vary depending on your ASUS model. After unscrewing, detach the stand from the display.

The display bezel, which is the outer frame of the monitor, is held in place by plastic clips. These clips can be released by gently pulling straight up on the bezel with your fingers. It is recommended to use a thin cloth when doing this to protect your fingertips and prevent smudges on the LCD screen.

Work your way around the display, lifting the bezel at each long edge and the center of the shorter sides. Be careful to pull straight up and not pry against the display, as pushing down on it could cause damage.

After freeing the centers of all four sides, move on to the corners. The corners are typically secured by two large clips that cannot be released by simply pulling up. You will need to use a thin, stiff prying device, such as a Jimmy, to press against the bottom clip in one of the corners while simultaneously pulling up on the bezel. This should release the entire corner.

Once one corner is freed, you should be able to gently twist and remove the entire bezel, releasing the remaining corners. Be cautious not to apply excessive force, as the bezel can be delicate.

With the bezel removed, you will now have access to the internal components of the monitor. The row of adjustment buttons will be attached to the display by a thin ribbon cable. Take care not to damage this cable as you continue with the repairs.

At this stage, you can proceed to repair or replace the faulty buttons. If you need further guidance on specific button repairs, there are online resources and forums dedicated to fixing ASUS monitor buttons that you can refer to.

Remember to exercise caution throughout the disassembly process, and always handle the internal components of your monitor with care.

Removing the bezel

To remove the bezel from your ASUS monitor, you'll need to carefully follow these steps to avoid damaging the display:

First, lay the monitor face down on a smooth, clean surface. This will give you access to the rear of the monitor, where the bezel is attached.

You'll notice four rubbery covers hiding screws in the rear of the monitor. Use a stiff pointed tool, like a metal spudger, to carefully pry out these plastic covers. Once they are removed, you can unscrew the screws securing the monitor stand.

With the screws removed, you can now detach the stand from the display. The display bezel is held in place by plastic clips, which can be released by pulling straight up on the bezel. It is recommended to use your fingers for this step, as any prying tools could potentially damage the LCD display. For added protection, you can lay a thin cloth over one of the long edges of the display before gripping the bezel and lifting straight up. This will help protect your fingertips and prevent smudges on the LCD.

As you lift the bezel, a few clips in the center will pop free. Be careful to maintain an upward pulling motion and avoid prying against the display, as pushing down on it could cause damage. Repeat this process for the remaining sides, working your way around the display.

Once you have freed the centers of all four sides, it's time to move on to the corners. Each corner is secured by two large clips that cannot be released by simply pulling straight up. For this, you'll need a thin, stiff prying device, such as a Jimmy. Press the tool against the bottom clip in the lower left corner (located beneath the HDMI logo). While pressing the clip in, pull up on the lower edge of the bezel. The entire corner should now pop free.

Repeat this process for the remaining corners as needed. Once one corner is freed, you should be able to gently twist the bezel to release all the remaining corners.

Now that the bezel is removed, you can proceed with repairing or replacing the LCD monitor buttons. Remember to follow the disassembly steps in reverse when reassembling the monitor.
