Why a black screen on xps l701x w7 i7 1.73

Black screen - no flashing white cursor in the upper left corner - no picture at all, i.e. the initial Dell start-up screen doesn't show up either:
- LCD is dead or isn't getting a signal - not an easy fix; or
- the LCD isn't being sent a signal - holding down the function [Fn] key and press display Function key to toggle through its settings (LCD panel only, Rear VGA output only, both LCD and VGA output)

Black screen - flashing white cursor in the upper left corner - the screen goes black after the windows loading screens come up but before the windows login screen comes up - it is probably a windows video driver problem. Try starting in Windows Safe Mode with VGA. Press [F8] after the Dell startup screen disappears to access the windows startup menu

My laptop screen is bright. Brightness control works but no picture. The picture is ok on external monitor. Sometimes a faint and incomplete picture appears on startup but disappears after a few seconds....

This might be a sign of a faulty LCD cable or screen inverter board.
The LCD cable transfers data signal from the motherboard & video card to the LCD screen. It also supplies high voltage DC power to the screen inverter board. The screen inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. It converts low voltage DC power to high voltage AC power needed for the backlight lamp.

I have 5 Dell 4310 WX projecors and I would like to display my logo when they start-up. Can this be done with the projector only or is a laptop necessary for this to happen?

I believe the Dell logo is hard-coded for the Startup, but you can change the Wallpaper form the Dell logo, to an image of your choice:

From the Setup Menu, or Others Menu, you can go into:
SCREEN SETTINGS—Select and press checkmark to activate screen settings. The screen
settings menu consists of the following options:

CAPTURE SCREEN—Select and press checkmark to capture the screen display, the following message appears on the screen.

NOTE: To capture a full image, ensure the input signal that is connected to the projector is 1280 x 800 resolution.

SCREEN—Select Dell to use the Dell logo as wallpaper. Select Captured to set the captured image as wallpaper.

RESET—Select and press to delete the captured picture and set back to the default setting.

I con't connect with lcd projector, xp windows

The video output will automatically switch to the data projector first when you power up the data projector first and then boot up the laptop.
When you power up the laptop first you can toggle the Windows image between the LCD screen and the video port/data projector by pressing the Fn key plus the F4 key. Pressing these keys each time will switch the display from LCD screen to video port only, to both LCD screen and video port, and back to LCD screen only.

Tohiba l300 completely blank screen

If the screen is always blank, even on startup , before loading Windows, than this is probably an hardware fault.

Try unplugging the laptop and removing the battery at the same time, wait 5 minutes, then put the laptop together. This will drain power and reset the laptop.

If that does not work, and you get no pictuer under any circumstance , then there is a fault.

If the screen is black with no light , then it is either a faulty inverter or a problem on mainboard.

If the screen is all lit, but is blank with no signal, then it is often because of a bad LCD ribbon cable , but can be again the video chipset on the motherboard.

Try connecting to an external monitor, if it works then problem is restricted to LCD/inverter and ribbon cable, if it does not work on external monitor is usually a bad video chipset on motherboard.

"no signal" message when laptop is plugged into projector

There is a key on the keyboard that has blue text on it. Something to the effect of LCD or CRT. With the monitor connected and turned on, press and hold the FCN KEY as well as the LCD/CRT key. While holding the FCN key keep hitting the CRT key until the image transfers to the external monitor

Bad connection between laptop and lcd projector

First, check all plugs and make sure there are no broken or bent pins in them. If the projector you are using have a replacable cable try to replace it to see if the cable is the problem. (borrow a cable from a friend or relative first so you don't buy one if it is not needed.)

If that doesn't fix it, try to connect a different computer to your projector to see if that is better. If so, the output port on your computer may be bad.

Also try to hook your compuber to a different monitor to see if that works. If no computers are able to make a good picture on your monitor, the monitor is at fault.

The fact that you can change the picture quality by wiggling the cable, and that it starts to search for a signal suggests that the cable or the plugs are at fault, but having the wrong resolution set up on your computer may also affect the image quality. Again, try to use a different computer as a source to eliminate (or confirm) your computer being the problem.
