    Has this problem been sorted out for you? If not what was the last thing you were doing with the laptop before this happened? Has it bee dropped in the past? Can you still see anything at all, even a faint image? Have you tried plugging in an external monitor?

    Regards

It sounds like the LCD back-light is out. There are two ways to fix this, neither are pretty.

1) (Cheaper, so try this first) - replace the inverter assembly.

2) Replace the display. This can easily exceed the value of the laptop, unless you can find one cheap. I've done it by finding a damaged machine on eBay (bad motherboard, good display), paid about $200 for the whole machine, instead of $500 for a parted-out display being retailed by a parts dealer.

Both operations involve major disassembly, and removing/installing the new display is tricky - - there are very delicate wires leading from the display to the plug that attaches to the circuitboard that thread through the hinge and into the chassis. Break these wires, and you've just wasted the display.

That said, _Excellent_ instructions are available at

www.ifixit.com - you can download the PDF and print it for reference before you get into the dis-assembly.

Good luck!

Reset button on a powerbook g4


The Powerbook G4 power button functions like a reset button if you hold the power button in for a few seconds until the computer powers down.
  1. Hold the power button in for a few seconds (until you see the screen turn off/go black and hear the fans & hard drive stop spinning).
  2. Press the power button again to turn your computer on.
  3. If you have more trouble, you may need to boot in Safe Mode or "perform a Safe Boot":
    Press and hold down the "Shift" key immediately after you hear the start-up tone. Release the "Shift" key when the gray Apple icon appears on the screen.

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.

Blank screen


Sounds like your screen went bad.
Close the lid, attach an external monitor, open lid and see if the screen appears on the monitor.

Resetting the PRAM may do the trick also:
You reset the PRAM by rebooting a Mac and then immediately hold down the Command+Option+P+R keys, you will then hear the Mac reboot sound again, signifying your PRAM has been reset. You must hit the key combination before the grey screen appears otherwise it won't work.

Happy New Year,

NO picture


Try attaching an external monitor to the notebook & see if you will get display on it or not. If this works, then you most probably have a defective or loose LCD screen cable, that need to either be replaced or properly connected.

Try replacing the inverter board. If that don't help then the next step is the back light, but replacing it is a bi.ch, so most people just replace the whole screen. Also, check that the video cable wire is not crimped/cut and securely fastened onto the logic board.

Vertical white wide band - Shivering fonts


Unfortunately that sound like a defective LCD panel. You can verify this by plugging the system into an external monitor. As long as the shimmering band does not appear on external display then it is the LCD. If it is under warranty I would suggest taking it into Apple.

LCD Problems


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.

Probably more like a Video cabling issue or a Screen assy getting bad connections.. Both have been seen here.
