Ok I have a G3 ibook recently my screen has lost some of its color quality. When I power up all is fine until the initial screen saver kicks in then it goes to what can only be described as old color settings were the color is all distorted and what use to perfect picture quality. So I struggle to see images and navigate. Please help [email protected] Rgd's Gavin

Volume down button+power until screen flashes release when boot loader screen pops up ( black screen with cammand prompt) use volume up and down keys to navigate .....Scroll down till reset system is highlighted and use the power button to select and system should reset from there.

For most situations, a restart is sufficient. If the computer has stopped responding, try these steps, in order, until the computer responds:

1. Force Quit (Option-Command-Escape)
2. Restart (Control-Command-Power)
3. Force Shut Down (press the power button for 10 seconds)

Only perform a PMU reset on the computer if none of the above steps resolved the situation.

Start up the computer from the system disk that up have. Put the disk in and start the computer with the C key pressed until the star screen comes up. Then troubleshoot from there.

If you have the original Install CDs that came with the iBook put in Install Disk 1.
When the Menu Bar appears go to Disk Utility (under file manu). Choose your HD and look for the S.M.A.R.T. status. It should be Verified. Then choose Repair Permissions. After that is done choose Repair Disk.

If none of this works find the Hardware Test Disk and run that.

To restore an iBook G3 to factory settings you need the installation CDs that came with the iBook. Ask your friend to find them. Sometimes you can purchase replacement sets on eBay, but they have to be for your exact model. Please realize that the original installation CDs that came with this iBook will contain OS 9, not OS X, so I question whether you really want to restore this machine "to factory settings." What you may choose to do instead is a "clean install" from a more recent retail OS X CD or DVD.

the only way to correct this is to open it . Have a local tech do it for you.

replace the monitor: it's lost vertical scanning

Hi, Sorry you are having trouble,
Sounds to me like you're going to have to re-open that puppy and check all the connections, sometimes, when putting it back together, some cables are stretched and come un plugged...
Be careful, go slow...

Has the hard drive been replaced yet? Computer hard drives have a 4 year average life. the last g3 shipped in 2002.................The G3 ibook was also infamous for bad logicboards or separated GPUs. Check

! for research only- I take no responsibilty if you turn your failing ibook into a brick or set your block on fire, but I know this technique very well!

The clamshell is 9 years out. The life of a hard drive under normal use is 4. Time to get a new machine? Does the clamshell have a firewire port?
