sounds to me like a defective lvds cable, the cable get's scuffed withind the years and then the signal can be distorted (or completely gone).

if you have a external monitor - connect the PowerBook to it - it should have a normal colored screen.

don't wait to long with replacing the cable, the problem can cause serious damage

Thanks for the info, I was afraid the cable could be the issue, I have read the tear down for the screen is not for the faint of heart, not as easy as opening up a Pismo or an iBook LCD screen/lid.

you're right, disassembling the screen is not easy - but i did it and it's ok, the "glue gets older and if you use an old credit card or something like that - you can open the screen in less than 10 minutes

Good idea, but when i change the LCD I will try to find one complete with cover. Could there be a software issue that could cause this?, swapped out old hdd and installed 2 different ones so I could update the OS to Tiger, video trouble went away with the first and come back on a small scale after the 3rd swap, but changed the resolution, colors from millions to thousands and it was gone in 20 seconds or so. I did remove the rear hinge covers, but found no chaffing and the plug is well seated to the mother board. since the update i have used it for a couple of hrs. doing various task with do trouble.....

as i wrote before, if it's working on an external monitor - it's a hardware isue. but it could also be a software related problem (in case you were not able to check it on an external monitor) - try to reset the pram:| 1. If the computer is on, turn it off.

2. Make sure the Caps Lock key is not down.

3. Restart the computer. Immediately after hearing the startup sound, simultaneously press and hold Command-Option-P-R. (If you do not hold down the key combination within 5 to 10 seconds after the computer restarts, you must repeat steps 1-3.)

4. Hold down the keys until you hear the startup sound again. Then release the keys.

5. If the computer shuts itself off, press the reset button on the back of the computer to turn it back on.

6. When the computer has finished starting up, restore any custom settings...| Apple Menu > System Preferences > Displays > Color and check your ColorSync settings. You can re-calibrate from here and alter the tint/hue you see on the screen

Thanks, I did a pram reset, no trouble restarting, I did discover the OS had not been updated, now that is done, I have not had any trouble with the LCD or colors. My problem know is not able to connect to the internet via wi-fi, seem the wi-fi router is set for WPA personal, my wi-fi card is the first generation airport, I did pick up a external card for the pci slot, a motorola wn825g, has the same chip as the one apple uses, when installed it is recognized as a airport extreme card, getting it to work has been a pain, is one suppose to remove old airport card before using replacement?
