The cover is glued on. So you’ll nee d quite a bit of force to bend it up. But then it’ll come lose glue point by glue point. At first I was afraid that I’ll break it.

Step 2

Remove the six 4mm screws using a Phillips #00 screwdriver.
Remove the screen, exposing the circuit board.
Turn device over to expose rear circuit board.

Step 3

Disconnect speaker from monitor for ease of access by unplugging wire.

Thank you so much for this - and thank you to the commenter who walked through the additional screen replacement steps! I’ve never done anything like this and I managed to replace the screen myself.

Step 4

Using a plastic opening tool, disconnect the ribbon cable connector.
Gently separate the ribbon cable from the motherboard.

Step 5

Using a Phillips #000 screwdriver, remove the four 4mm screws around the edge of the motherboard.
Flip the motherboard away from the front case to reveal the screen on the other side.

Step 6

Using a plastic opening tool, carefully pry the top retaining frame off of the screen. Start in one corner and work around the bottom of the frame.

Step 7

Using a plastic opening pick, carefully pry a corner of the screen away from the motherboard.
Lift the screen off of the motherboard.

What do you do when you reassemble everything and the screen only shows white and nothing else? You can still hear the sound, but no image.
