Strange Monitor Display

[Chintam]

I am having a strange problem regarding my monitor display. My monitor suddenly started providing green color lines in the monitor display, that gets more problematic as the display goes completley white in color. Then, as i try to close the screen i also noticed the monitor display becomes black. Then i made the computer cpu side lid open, the screen turns white again as i can hear some sound it generates, monitor screen still turns white in color. Then the screen again goes black in color.

Please help me with this problem as i don't know what is wrong with my monitor

Make sure the monitor is on. If no power light (green or orange light) is seen on the monitor display try pressing the power button until it comes on. If no light comes on after several attempts continue to below connections not connected properly.

check your internal connections.
Could be a loose Video card.

Turn the computer off and disconnect it from the power
Take off the side of the case and touch the bare metal chassis to discharge static.
Remove Video cards from their slots

Reseat Video card.

Is this a CRT [cathode ray tube] monitor of Flat screen

If your computer monitor was on and you stepped away from the computer and upon returning it was black it's likely that the computer is asleep. Try moving your mouse, clicking the mouse buttons, and/or pressing any key (space bar) on the keyboard to wake it up.

If you are not receiving power from a known working wall outlet and if the power cord is removable, replace it with the one connected to the computer and attempt to power on the monitor again. If the monitor still does not get power or it is not removable, it is recommended that the monitor be replaced or serviced at a local TV / Computer repair shop.

Could be a videocard going bad, dirty connection, or the wire's between the video card and screen could be breaking from opening and closing alot. Doesn't sound like a software issue. What model laptop?

If the light is orange or flashing ensure that the monitor is not in a suspend mode by moving the mouse or pressing a key on the keyboard. If the computer does not get a display by moving the mouse or touching the keyboard, turn off the computer and monitor and reconnect the data cable from the back of the computer, and if removable, the back of the monitor. Turn the computer back on; if you still encounter the same issue, continue reading through the other possibilities.

Ensure that the brightness and contrast is turned up or attempt to adjust the brightness and contrast. If adjusting the brightness or contrast has no affect on the monitor continue reading through the other possibilities.

Disconnect your monitor and attempt to connect it to another computer. This can be a friend or family's computer and/or it can be taken to a service center.
Borrow a computer monitor and connect it to your computer. This will not harm the other computer monitor in any way.

If your monitor works on another computer it is safe to assume that the video card or potentially the motherboard within the computer is bad.
