G4 iBook screen fades to black on start-up

Hi,
My G4 iBook screen goes dark shortly after I power-up. It's like an invisible finger hits the F1 key - I can actually see the "bars" reducing. If I hit the F2 key, the screen goes bright for a second or two and then fades again.

It's almost as if the F1 key is stuck. I have lifted the keyboard, cleaned the recess and checked for any obstructions.

Taking the battery out and rebooting a couple of times, as well leaving the two keyboard locks unclipped, solves the problem and thereafter the G4 is fine.

What could be causing this and how easy would it be to fix it?

The machine is a 2005 model but I'm not keen on replacing it just yet.

Thanks,

Paul

It sounds like that key is sticking.

You might want to look on eBay for a replacement keyboard. I'm not sure how difficult it would be to unplug the old keyboard and plug in the new. Opening the iBooks is a challenge, but maybe the keyboard can be plugged in through the hole in the top. Not sure.

Good luck!

Hi, I have an Ibook G4 and i have a problem with my backlighting, it is very dim hardly visable. Is there any free solutions ?


F1 and F2 on the keyboard make the backlight go dim or get brighter. connect an external display to the computer if the issue doesn't show up on the external display it's the LCD inverter board that will need to be replaced.

My G4 iBook screen goes dark shortly after I power-up, even If I hit the F2 key, the screen remains dark.


Hi,
Got the same problem with my ibook G4.
I have research on how to fix it, and found out that most model of G4 has the same problem.
I soon found out the main problem and the solution, it would require some skill in soldering and dis assembling the whole laptop.
Go to this site and hope it will help you just it like it helps me a lot!

I Apple Ibook G4 Machine 1. Machine boots up fi...


Machine 1. The dim display is likely the result of an old or failing compact fluorescent lamp (CFL), generally refered to as the backlight lamp. This CFL is a long, narrow, delicate, and normally very bright light that runs along the bottom of the LCD screen and is powered by the inverter. You could replace the CFL yourself however or simply look for a used iBook screen assembly or the LCD by itself for about the same cost. CFL sell for $7-15. The first time you attempt to replace it, you should buy two because you'll likely break the first one learning how it work. Watch out for mercury! Machine 2 The graphic processor unit (GPU) is attached to the logic board using a grid of solder balls. With normal wear and tear the logic board flexes and breaks and cracks the solder joints which results in the same exact symptoms that you are experiencing. The chip must me removed and the solder joints "re-balled" to fix it correctly. Again, you could do this yourself or find a reputable service on eBay for $30-55.
Sometimes, if you grip the iBook with your left hand and apply pressure just below the alt key with your thumb and your fingers on the bottom, while booting, the symptoms go temporarily appear to go away. It's a good way to test for this very common iBook problem.
Good luck!

Ibook g4 screen issue


That screen will most likely be compatible - I work on these for a living. The G3 laptop screens are usually not compatible with the G4 laptops, but all G4 laptop screens are compatible with eachother (provided they are the same size, of course.

Ibook display problem


You can reset the pmu this might help to stable the display,this is only used as a last resort and not a possible solution.
  1. If the computer is on, turn it off.
  2. Reset the power manager by simultaneously pressing and then releasing Shift-Control-Option-Power on the keyboard. Do not press the fn (Function) key while using this combination of keystrokes.
  3. Wait 5 seconds.
  4. Press the Power button to restart the iBook computer.

Ibook G 4/12.1/1.33/5aptx.....will not start


Some computer react this way when the logic board goes bad or have a defect in it.  
First, Try this:  
Remove the battery.  Plug back in the power cord, then press and hold down the power button til you hear a loud beep sound. then release it.  If the computer starts back up... Then you should be okay.
If not, it may has something to do with the logic board.
Let me know if the above works... We may can try some other things if not.

When i turn on my mac ibook g4 the screen gets light then suddenly goes dark and seems to boot up but the screen is black but i can faintly see the desktop icons. What should it do?? thanks


your backligny is probably off. try "increaseing the brightness" on your screen. on macs that should probably be one of the F-keys at the top of your keyboard. I think brighter is F2 or Fn + F2 or somethinglike that. just find the symbol. Do this while your laptop is plugged in to make sure it's not just dimming you screen to save battery.

Ibook screen issues


This is nearly impossible to diagnose via the Web. It sounds like the logic board is at fault, but not necessarily.

On an Apple system, this is an indication that it thinks there is little or no battery left and goes to sleep to protect data loss. Your battery might be going bad (showing a full charge, but lasting for only a few minutes) or there may be a problem with your power supply.
