Introduction

Replace the display assembly from your Acer X191 monitor. The display assembly includes the front plastic frame, the LCD screen, and some metal armature on the back of the LCD screen.

What you need

Step 1 Stand

Lay the monitor on a flat surface, facedown.
Use a #1 Phillips screwdriver to remove the 4x 10.2mm screws securing the stand to the back panel.
Remove the stand from the back panel by pulling it up.

Step 2 Back Cover

Remove the 2x 9.8mm Phillips #1 screws securing the back cover to the monitor.

Edit

Step 3

Work your way around the monitor, putting the flathead screwdriver into the space between the front and back covers, and prying up.
Twisting the screwdriver can help, but you can easily mess up the plastic without getting anything out of it by doing so. Be cautious.
Ideally you want to pry at the locations that have the little gaps, which are locking mechanisms.
You should hear a poping sound and the back cover should lift a little if you are prying at the right locations.

Step 4

I've highlighted the locations of the locking mechanisms for the back cover, try prying in these locations for the best results.
Right side of the monitor.
Top of the monitor.
Left side of the monitor.

Step 5

On the bottom side, be careful not to pry on the monitor buttons.

Step 6

The monitor back cover will then pull right off.

Step 7 Display Assembly

Remove the 2 pieces of yellow tape.
The bottom one have a thin sheet a metal on the underside which you need to take off too, if it does not come off with the tape.

Step 8 Button board

The button board is secured to the front frame by 2 plastic locking mechanisms.
To remove, insert a Flathead screwdriver into the gap to push the locking mechanism back a little, while pulling up on the board.
I found it easier to do one side at a time.

Step 9

Remove the bundled cable connector that is going to the top of the monitor. Grab the black tape that holds all the individual wires together, and pull gently.
Be careful to pull evenly on all the wires. You can do this by pulling strait out and not at an angle. Jiggling a little bit can help, but be careful.

Step 10

Remove the bottom foil tape from the back of the LCD.
Be sure to keep it. It helps dissipate static to the ground while the screen is in use. I recommend leaving the side of the tape that is sticking to the shield, where it is.

Edit

Step 11

Remove the remaining 2 pieces of foil tape from the back of the LCD.
Keep the pieces of foil tape. They help dissipate static to the ground while the monitor is being used. I recommend leaving on side stuck on the shield.

Edit

Step 12

Remove the 4 connectors that bring power from the powerboard to the LCD.
The connectors have a plastic locking tab on them, and the available space make them very difficult to pull out.
Next step shows one way to remove them without too much trouble.

Step 13 Removing the power cable connectors

Insert a Flathead screwdriver into the holes on the top of the shield. Lodge the tip between the socket and the connector and slowly push the connector out of it's socket.
Be very careful that you are NOT pushing on the socket itself, but the connector, ideally on the locking tab.

Edit

Step 14

Use a Phillips #1 to remove the 4x 8.5mm screws that are securing the shield to the display assembly.
Pull the shield up carefully.
The power board and logic board are inside the shield.
