Before you proceed, make sure you pay special attention to the way the small plastic part that covers the radiator fins is held in place. You will need to know how it attaches when you reassemble the laptop.
You do not need to actually remove the part at this time. It is held in place by the rest of the back cover and will fall off when back cover is removed in the next step.

Step 10

After removing the screws, use your fingers to lift the back cover off the laptop.

Step 11

Remove the back cover and place it somewhere safe so you can locate it later.

Step 12 Keyboard

To remove the keyboard, the speaker cover must be removed first.
To do this, first remove the two screws (Length: 2.3 mm) highlighted in the picture.

After the screws are removed, flip the laptop over so the keyboard is facing up and move the screen to its upright position.

Step 15

To start removing the speaker cover, use your finger to lift up on the exposed corner of the black speaker cover, located near the bottom left corner of the screen.
Slowly pull the speaker cover off from left to right, making sure it snaps off little by little.

Step 16

After removing the speaker cover, remove the four screws (Length: 3.6 mm) with your Phillips #0 screwdriver that hold the keyboard in place.

Step 17

Lift the free edge of the keyboard and fold it back to expose the ribbon that connects the keyboard to the laptop.
The large silver surface you see at the bottom of the picture is the back of the keyboard.

Step 18

On each side of the white plastic connector, there is a tiny black tab that locks the ribbon into place.
Use the sharp edge of a spudger to slide the black tabs away from from the white plastic connector.
Once the tabs have been extended away from the connector, the ribbon can be removed from the keyboard.
The keyboard is now completely disconnected from the laptop.

Installing Sony Vaio PCG-7A2L LCD Screen: step 24, image 3 of 3

Use a Phillips #0 screwdriver to remove the two screws (Length: 6.9 mm) that attach the screen to the body of the laptop.
Do not discard these screws. They will be used to attach the new screen to the laptop.

Step 25

The LCD screen is now completely disconnected from the laptop.
Move the old display out of the way so you can install the new display.

Step 26

To install the new LCD Screen, first align the new screen with the vacated screw holes.
Use a Phillips #0 screwdriver to reinsert the screws(Length: 6.9 mm)and secure the new screen to the body of the laptop.

Step 27

Installing Sony Vaio PCG-7A2L LCD Screen: step 27, image 3 of 3

Place the power and display cables for the new screen into their respective grooves.

Step 28

Installing Sony Vaio PCG-7A2L LCD Screen: step 28, image 3 of 3

Once the new screen and its cables are securely in place, attach the three cables to their corresponding ports.
For each cable, place the connector on top of the port and align the two as close as possible.
To connect the power cable, use your finger to push downward on the middle of the connector until it snaps into place.
To connect each display cable, use the flat end of a spudger to press on the top of the silver connector until it snaps into place.
Snapping the connectors into place does require a little bit of force, but be careful, too much force can break the motherboard. If the connector doesn't snap into place with a moderate amount of force, realign it and try again.
Make sure the two display cables are connected to the correct ports. The grey cable should connect closest to the screen.
