PowerBook 180c Display Capacitor Replacement Guide

Note: This process requires soldering. This is not a soldering tutorial, and you will be expected to already know how to solder for the following steps. Don't be intimidated though! As long as you have a steady hand and good eyesight, it's not actually that difficult.


Before You Start: Make sure the computer is powered off and unplugged. If working, remove the battery.


Step 1: Removing the display bezel

1: Use a small, thin tool or a fingernail to carefully remove the 2 rubber screw covers near the bottom of the bezel. They are easily damaged, especially if you use metal tools, so be careful.

2: Remove the 2 torx screws hidden behind the covers. Be careful! They screw into plastic standoffs that break extremely easily. If they are already broken, you may have to take extra steps to get them out.

Display Screws

How to remove the screws if the standoffs are broken (They just spin endlessly in their metal threads and don't come out):

Try to seperate the bezel from the housing as much as you can. Look inside the gap and try to find the metal threads that the screws thread into. If they've seperated from the now broken plastic, you have your issues. Try to slide thin pliers into the gap and grab onto the threads. From there are you should be able to remove the screws.


3: Use a thin plastic tool to carefully slide around the seam between the bezel and the housing. Be careful not to break any of the fragile plastic tabs used to secure it into place. Start at the bottom. It should unclip itself very easily.


4: Seperate the bezel away from the rest of the housing.



Step 2: Removing the display

1: Carefully bend away the blue shielding on the right side of the display to expose the backlight inverter board.

WARNING: The inverter board carries dangerous high voltages required to drive the CCFL backlight tube. Make sure you do not touch components of the board while the PowerBook is powered on or plugged in. If you have a functioning battery, remove it!

2: Use your fingernails or a thin tool to carefully disconnect the backlight cable. Never pull on the wires themselves, as they are quite fragile and may tear. This connector can be difficult to remove, just carefully work at each side until it pulls free.


3: Unscrew the 4 torx screws that hold the display in case. They are threaded into the same fragile standoffs that commonly break on the hinges, although these aren't being flexed so they aren't usually broken. Still, be careful. Make sure to hold onto the display when removing the final screw, so it doesn't just fall, risking damage.


4: Pull the display free from the housing. You will need to bend the blue shielding out of the way and carefully fold it down so it lays flat on the keyboard. Be careful, as pulling it in the wrong direction risks damaging the fragile display ribbon cable.


5: Carefully pull the display connector ribbon free from the 2 connectors on the display controller board. They release similar to how the inverter cable releases. Once again, do not pull on the ribbon itself.


6: The ribbon cable is adheared to the display assembly. DO NOT try to blindly pry it up or it WILL break. Instead, use a thin plastic tool such as a plastic guitar pick or a credit card to carefully pry up at the cable until the adheasive has been broken. If using your hand to pry, pry slowly, carefully, and NEVER pry sideways. I broke a hard drive ribbon doing just that.

Once free, lift up the cable carefully and leave it on the computer. Move the computer to the side and place the display on your work surface.



Step 3: Recapping the Display
