Tthis just started. The sounds take place but the screen stays black through the boot process. The sign on screen appeared faintly and then turned black. Any ideas?
Shine a flashlight on the dark screen to see if you barelysee the icons on the desktop. If so, then the LCD Inverter is bad.
Plug in an external monitor and see if the display shows up on it. It can beany kind of monitor even the old big fat crt monitors as long as it has a vgacable to connect to your computer's vga port. If so that proves yourvideo card is ok. The video will show on most systems when you rebootwithout you having to do anything. Some systems will require you to hit the FN(Function key) + F1 thru F12. Hold down the FN key then hit the correctkey for displaying on the monitor (F1 thru F12). The correct key willnormally have CRT/LCD on it or it will have the icon of a display.
If you see no icons by shinning a flash light and the external monitor works,then your screen is bad. If you see no icons by shinning the flash lightand nothing shows on the external monitor, then most likely your video card isbad.

Try pressing FN/F5 keys simultaneously, or the key that toggles internal/external Display. Look for the double screen Icons on the keys.
Tap the Pause Key.
Restart and press and hold F8 key when Toshiba logo appears. When the boot Menu appears, select Last Known Good Configuration.
If all else fails ther should be a reset button on the side of the LT. Consult owners Manual for location

The issue appears to be cosmetic if the system boots to WIndows and there are no display issues using the system. Some systems I've seen have a bit of video distortion between the BIOS splash screen and the desktop. A couple things may change that. Update the system BIOS and the video driver to the most current available

Hi,
The display drivers maybe corrupt.
Boot the machine into safe mode. Right click on My Computer (XP) Computer (Vista) and select manage from the sub menu.
When the window pops up select Device Manager.
A device list will populate. When it has look down the list for Display Adapters. Click on the + icon next to Display Adapters to it expands. Right click on the display adapter and select uninstall.
Restart the computer and let it boot in normal mode.
If it boots in normal mode let it detect the Display and install the drivers for it.
I would be a good idea to update the display drivers via the Dell support website.
If it still won't display in normal mode please post back.
Good luck.

This is probably a hardware issue with the monitor. Just to make sure, uninstall, and reinstall the monitor's driver. If that doesn't fix it, it's a hardware issue.
You will have to either take it to a shop, or contact the manufacturer (your computer should be under warranty if you've had it for less than a year).

I think this is a problem with the laptop's LCD display. To verify this connect the laptop to an external display and see if it resolves the issue. If it does then its confirmed that its a display related issue. Since the issue has appeared suddenly I dont think its a serious problem. May be just loose/disconnected connectors. Should be a 10 minute job for a qualified technician.
If the external display too doesn't come on then its an issue with the graphics card and you may need to replace it.
