Mac Repair London carries out a screen replacement on the PowerBook G4 from our Central London workshop, for home users and businesses.
On the 15-inch aluminium PowerBook G4 the best-known fault is white spots appearing on the display, caused by pressure on the backlight diffuser. On the 17-inch, lines across the LCD are more common. We diagnose whether the LCD, the inverter or the display cable is at fault, then replace only what has failed using tested parts. Because these screens are scarce, a used panel in good condition is often the only realistic option and we say so upfront.
Signs it needs a screen replacement
- White spots on 15-inch displays
- Vertical or horizontal lines on 17-inch panels
- Backlight failure with a faint image
- Broken hinge or loose lid
How we do it
Before quoting for a new screen, we connect an external display and inspect the display cable, so we know whether the fault is in the screen itself, the cable or the logic board.
Before we hand it back, we test the new screen on a full range of colours and brightness levels and check the camera and sensors.

Before you bring it in
Take a photo of the damage while the Mac is on, especially if the fault comes and goes. It helps us tell a panel fault from a cable or graphics fault.

Questions we’re often asked
What parts do you use?
We tell you before fitting whether a part is an Apple original, a tested part recovered from a donor machine, or a high-quality compatible part, and the price reflects which you choose.
Can you fit an SSD while it’s here?
Yes. This model uses a 2.5-inch ide (parallel ata) hard drive, and swapping to an SSD at the same time is often the best-value upgrade you can make.
Is there a warranty?
Yes, our repairs come with a warranty on the work and parts. Ask us for the terms that apply to your repair.
