iMac G4 Screen Replacement
Introduction
Go to step 1This guide shows will help you install a new display into your iMac G4. You can purchase such display from iFixit, other websites online, or possibly a local business in your area. You will also need a screwdriver, size 00 with a Phillips and a hexagonal attachment.
What you need
-
-
Position the computer so that all three screws on the underside of the display are accessible. This may be upright or laid flat with the screen face down on a soft surface.
-
-
-
The next cord to unplug between the two panels of the display is the inverter cable. This will be located under the inverter closer to the bottom of the screen and will have only two cables connecting at a smaller white connection.
-
Like the inverter cable, grasp each side of the white connection and gently unplug the inverter cable.
-
-
-
The third, and final, cable you will need to unplug is the TMDS connector. This is located under a rectangular strip of black tape that has a gray and black cord coming out of one end.
-
Peel back the black tape, starting at the end with the cords protruding out.
-
Under the black tape, you will see the gray and black cords going into a connection that looks like it is wrapped in aluminum foil. Grasp that connection and pull carefully in the downward direction toward the bottom of the display.
-

-
Remove old display from frame and place new displace with same exact orientation as the old.

The instructions say that I can buy a replacement monitor here, but I can’t find in on this site.
Note; on my iMac G4, I need to remove all screws around the bezel with the exception of the 2 Side Center screws which are holding up the backlit LEDs. Slightly different than your tutorial however this was an excellent tutorial. Just replaced the screen for my daughter all she needs to do is remember her passwords
Step 3 should have an arrow to show where to slide. The current photo is misleading.
In fact, the LCD is inside a cast frame, the cast frame is permanently attached with the transparent frame. Then the cast frame is locked to the back metal shield of the monitor with sided-“H“ hooks. The correct procedure should be: 1. unscrew three screws at the bottom of the monitor. 2. hold the transparent, slide it against the back cover upwards, ~3mm, then the LCD + transparent frame + cast frame together can be separated from the back of the monitor.
Another trick is unscrewing the center screw last, then pushing the screw back, the LCD combo will slide upwards.
