DELL Latitude 740 model 2022 screen replacement

This is a guide on a replacing a screen on the Dell Latitude 7420 model 2022

For the replacement process we’ll need the following tools:
- a Plastic Pick
- and a Tweezers


To begin turn off the laptop and disconnect the power cord. Using plastic pick pry off the bezel
on the inner edge of a bezel. Start from the side and go along the perimeter. Using fingers
start unsnapping the tabs underneath the bezel. Go around the perimeter.
Close the laptop and using plastic pick unsnap the bezel at the bottom edge.
The hinge covers are part of the bezel. Using a pick release both hinge covers.
Remove the bezel.

The LCD screen is held in place with adhesive strips with loose tabs hanging in the bottom
of the screen. Using tweezers pick the tab on the right side and pull out the adhesive strip.
Pull out adhesive strip on the left side. Place the screen on the keyboard.

This a rare case when video connector is secured with TWO layers of tape.
Peel off the first silver tape. Then peel off the clear tape. Using plastic pick open the
connector’s bracket. Disconnect the video cable. Discard the old screen.

Place the new screen on the keyboard. Reconnect the video cable. Close the connector’s
bracket. Secure it with two tapes.

CAUTION! It is very important not to force any connectors. Also make sure not
to twist or slant the connector when plugging it in.

Lift the screen up and lean it on the back cover. Test the new screen.
The screen is working and we can finish reinstallation process.

We are going to use new set of adhesive strips, which you can buy on our site:

Clean the back of the screen with alcohol. Apply new adhesive strips. Clean the inner surfaces
of the back cover. Lift the screen up and apply some pressure on the sides.

Replace the bezel. Insert the hinge covers into the slots. And then go around the perimeter
snapping tabs back in place. Close the laptop and make sure that bezel in snapped in place
at the bottom.
