Is the display data cable broken?
Dear iFixit community,
I have a PowerBook G4 Titanium DVI A1025 867 15''.
The screen, depending on what angle I have the laptop opened will either show a pinkish screen over the background of the desktop or it will black out. Once in the right position I can work with it just fine. However the slightest change in angle and it will become very unstable. When I connect it to an external screen it works flawless.
So this is my conclusion. The display data cable must be broken as the display is fine and the gpu output is fine too.
Am I right with this assumption?
I just bought this cable here from iFixIt:
and hope that this is the right one.
Given the cable is the cause of error would it be advised to use this guide here:
to replace the data cable or would it be better to go to a local repair store with the new cable and let a professional do it? I have little experience with fixing laptops, I am better with the software part.
Is there a high chance I ruin the working screen and or cable doing this a first time round?
Thanks for all your input and help, it is really appreciated.
A damaged display data cable can cause video defects — 1 available at 49.95 each.
These guides are very good and if you have any mechanical skill at all you can do this. Just make sure you have the tools required at the beginning of the guide. Find a quite spot to work without distractions. Have good light. Try to do it all at one sitting. Touch the center screw of a wall electrical receptacle to ground yourself out to avoid ESD. If you have a digital camera, taking pictures as you go can help with reassembly. Keep organized, some people use masking tape and put the screws in order as they go. Have fun and enjoy learning a new skill and the confidence that comes with fixing something and of course the money saved.

huuuuummm, are you sure you're loosing video when moving the lid ? Often, pink background color and black screen moving the display are symptoms of a dying backlight bulb and bad inverter cable.
When the screen becomes black just pass a flashlight over the top cover Apple icon and carefully check if you still see a faint image of the desktop onscreen.
