It loves to get bent, which pugs up the light reflecting into the transmitting prism layer, so you get dark/light areas. The problem is that taking the metal housing off the front of the panel exposes the stack of layers, meaning that if you let these lose, it's problems.

In fact, I'm almost sure you could use that toshiba walkthrough to do it. I just replaced the CCFL in a 15' powerbook LCD panel (1280x856). I'd like to hear if someone knows more about the subject.Īnother thought that has come to mind: the current Macbook Pro machines have LED backlights, don't they? I know that the screen size is slightly different (1440x900 unlike the Powerbook G4's 1440x960), but maybe the backlight assembly could somehow be adapted for that display anyway? Again, no photos or details, so I don't know if this is just an estimated guess or fact. Other posts indicate that the backlight is glued in some manner to the display and it's hard to remove/replace without damaging anything. Unlike what I read about a lot of Mac users buying a new laptop every 2 years I can't afford that luxery (neither do I see the need for it -we're supposed to think about the environment as well, aren't we). But since my LCD display works fine and doesn't even have a scratch I find this a complete waste of money. There are a few DIY Powerbook screen replacement sites around. Some people suggest that a completely new screen be bought (around US$ 200-300, or around US$1000 if bought directly from Apple) and replaced.

The few posts I've read on the subject seem to be mostly guesses or estimates. My 1.67GHz 15' Powerbook G4 has been getting a dimmer display and I've read that this is a typical symptom of an aging backlight.ĬCFL (Cold Cathode Fluorescent Lamp) type tubes are used for this and replacements cost around US$ 10-15 for laptops according to LCDparts.įinding information on how to replace it in a Powerbook seems pretty impossible.
