Many laptops have the ability to connect to an external monitor. On most the monitor can be used in a manner similar to a projector output for presentations. On some the monitor can be configured as an extension of the desktop, essentially giving you a double wide screen.
If the problem with your laptop is with the LCD display and not with the display circuitry, it may be possible to use it with the external display. If the problem is not with the LCD screen, chances are that the external monitor won't work either.
It's possible the Monitor has failed, but here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
A computer monitor has a front-mounted LED that displays its current status and flashes in the event of an error. When an error occurs, the flashing may be accompanied by an error message on the screen. If the screen does not display an error message, the problem most likely falls into one of four common categories.
Unsupported Display Mode A video card has the ability to send output to the monitor at many display resolutions and refresh rates. However, no single monitor is capable of supporting every possible display mode. When the video card sends an unsupported display mode to the monitor, the monitor shuts off to prevent damage and blinks, or displays an error message. Standby Mode b> When a monitor detects no video signal from the computer, it assumes that you have turned the computer off and enters standby mode to reduce power consumption. Dell and HP monitors display an amber light when in standby mode. The status light on an Apple monitor blinks slowly. Incorrect Power Supply Some monitors such as certain Apple Cinema and Studio displays use external power adapters. Because different power adapters may have similar connectors, these monitors are designed to detect when an incorrect power supply is connected and blink the status LED rather than attempting to turn on. In the case of an Apple display, the LED blinks in an alternating short and long pattern. b> Backlight Failure b> A flat panel LCD display has an LED or fluorescent backlight that illuminates the pixels and makes it possible to see the contents of the screen. If the backlight fails and requires replacement, the monitor is unable to display any information. In some cases, you may be able to resolve this issue by turning the monitor and computer off, disconnecting and reseating all cables. If the monitor still has a backlight issue, it requires professional service.

Ok seems like an issue with the LCD screen . Try these steps :
1. do u hear the windows login sound when you turn on the system ?
2. Check for any lblinking lights on the system. Press the caps lock and num lock and check if it responds.
3. Do u have a Desktop at home ? if yes then you can connect the monitor to the system and check for the display.
4. check for any cracks or any kind of damages. Reseat the battery and then power oN . Check for the light on the AC adapter too.
IF the answer is YES for the above then its a issue with the LCD screen.
check your numlock key presss it then check numlock led if it on /off then your computer gives dispaly to monitor perfact then when you power up ther computer press F8 key then enter in enable vga mode if you see safe mode and other mennu.
But if you can't able to see those menu then you have to check your monitor to cpu vga cable connection.
Also check your monitor is properly working? or not.
Hi , The monitor flicker problem. The monitor when turn on will display image for couple of second then turn black. The monitor status led is still green. This will happen each time it is turn on. The symptom at appear to come from the inverter board.
If it turns black again, try to check first if it's just the LED's that are defective. If you push the monitor 40 degrees down, and you can see very faint display from that angle, then it's probably that the LED's are the culprit, and you can have it replaced for a less price.
