This doesn't sound good, but there are a few things to do. First, if you replaced the screen yourself and feel comfortable opening up the case again, do so and check the connections. There might be something lose that's making the problem. I'm guessing not though. It sounds more like a logic board problem. You can try a few options though.

[]Reset the PRAM

[]Leave the battery out and the unit unplugged for a day and press the power button about 10 times to discharge the laptop. (sometimes does something to settings)

[]Hook it up to an external monitor to see if you have an image. This will tell you whether it's an internal thing or not. If you don't get an image on an external monitor, you probably have a bad logic board. Sorry I can't help more.

Mac book pro. Black screen cannot start but with boot sound


Have you tried connecting an external monitor.

A boot chime means the Mac has passed POST, that the screen remains black initially suggests there is a problem getting image to screen which could mean a bad cable to the LCD or the LCD display its self is having problems.

By connecting to an external display you verify the graphics on the logic board is functional, and it could get you up and running till the display problem is fixed.

Also try powering up and when you hear the chime, hold down the COMMAND+OPTION+P+R keys, and keep holding them till the machine has chimed 3 times, this will reset the 'BIOS' in case there is a glitch there stopping the display from showing up.

There is a white screen when i turn my macbook on but nothng more


Since so many different brands and models of laptops exist, specific causes of a white screen vary from laptop to laptop. The likely cause in most cases of a white screen on a laptop is a connection problem between the LCD screen and the video cable running from the motherboard. The issue can also reside strictly with the motherboard or the screen might contain a defect.

You can diagnose a white screen problem by opening up the laptop display case to determine whether a loose video connection on the back of the LCD screen exists. Reconnecting the video cable should resolve the white screen; a video cable reconnection that does not fix the white screen narrows the root cause to a problem with the motherboard or the screen.

"Motherboard Problems"

The only way to determine if the laptop screen turns white due to a motherboard problem is to test out a different, working LCD screen with the laptop. This requires the user connect the inverter board--the power supply for the LCD back light--and the video cable to the test LCD. If the test LCD works with the motherboard, then the laptop's screen needs replacing; otherwise, a new motherboard is needed because there is no way to replace an integrated graphics card on a laptop motherboard.


Thanks.

White flash/flicker on Powerbook G4 LCD monitor


There might be an internal device in your computer that is causing this, I have a 4 year old G4 myself, and a defect right hand side light sensor both caused purple stripes on the screen and made it go to sleep mode every time left hand side light sensor was covered.
You could run a hardware test on it: http://www.info.apple.com/support/aht.html
Maybe you could try to deactivate the light sensors in System Preferences?
These are more suggestions than a solution, but maybe you could start there. Good luck, I hope you get it solved!

Backlight


The problem is fairly common and while you could test the long-shot possibility that it's not the inverter but the actual CCFL "bulb" (a tube really) that produces the light and sits in the bottom of the LCD panel, the chances are that it's a circuitry problem on the logic board. I've never had luck replacing inverters in these computers (though it works like a charm in PCs).

With the symptoms you have though, it might make sense to try the $20 inverter rather than replace the logic board. It's really quite simple. Just follow the instructions on THIS PAGE and select Apple MacBook Pro (even though you have a PowerBook it's almost exactly the same.)

It will walk you through taking the back off and pulling the LCD, but just notice that on Diagram #2 it shows you where the inverter board is. Just take it out, remove the two cables going to it and replace it with a known good one from eBay. It will be a great $20 way to check a cheap solution. After that fails, replace the logic board.

Or, for more fun, find another person with another laptop who doesn't mind you pulling it apart. Almost all 12" laptops will use a similar CCFL, so you can plug your LCD panel into just the two prong CCFL plug (shown in step 3 of the walk through). If you find someone else with a powerbook or iBook I know for certain that your screen's CCFL plug will fit.

So you could do all this or you could find someone on Craigslist to do it for you for a pretty cheap cost. Good Luck.

to peachgroup: if you have a lighted White screen, it is something completely different.

When turning on my macbook pro


Does it work with an external?

1) If it does boot through external. Your LCD, LCD inverter, or LCD cable may need replacement.

2) If it does not boot, then it may be problems with video card or motherboard problem. May need motherboard replacement.

Please let me know the follow ups of it. Thanks!
