SOURCE: laptop screen flickering

You most likely have a faulty CCFL lamp, To determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

SOURCE: Dell Latitude CPt screen is black at startup and stays.

It sounds like your PC isn't completing its POST. (pre operating system test)

This is usually caused by faulty hardware. Your best bet is to first remove anything you have recently installed. If that doesn't apply/work, try removing various hardware devices (CD/DVD drives, memory, USB devices) until you get the machine to boot up.

If even after removing every piece of hardware possible the machine still exhibits the same behavior, it is likely a problem with the motherboard (or other "permanent" hardware).

Toshiba will not boot


It needs those things to start up. If you reinstalled them in the machine and it won't start up you need to check some things:
Does the screen flicker when you power it on or does it stay completely black? If it stays completely black, then the connection from the screen to the computer itself is lost. Normally it is caused by a broken cable.

If the screen flickers and then goes black, then check the following:
Does it beep at you? If it does, then the amount of beeps is important. It will state in the users manual what that numbers mean.
If it doesn't beep, then my best guess would be that there is something wrong with the power distribution in the machine.

Screen flickers and then turns gray


Access BIOS and test if the flickering continues.
If not, it is a Software problem, do a full system recovery
If yes, it is a hardware issue, better contact Toshiba tech support to have your LCD repaired if you are still in warranty.

If your not in warranty, you need to check out the LCD harness that might have been loosely connected.

Hope this helps...
