Computer screen is white and blank..the last thing i did was run a disk defrag and now its completely white...i dont know how to reset the monitor and i hook it up to my laptop to a double monitor options...


Not sure what you mean by resetting the monitor but pulling the power should get it back so you can see the Onscreen menu. If you can get inot the menu there is usually a reset or factory reset option.

As for dual screen w/laptop. The hardest part is telling the laptop to use the extra monitor. On my laptop the Function Key and F8 cycle the external monitor. You also need to tell windows if the new monitor sits to the left or the right of the laptop so the mouse works correctly.

Screen went white


The white glow with no picture means that either the ribbon cable connection between the logic board and the monitor has come lose or dirty contacts, or the LCD Controller (T-CON) board (part of the LCD panel is not getting 5v or 12v depend on LCD panel from the logic board or the LCD controller board has blown fuse, see pictures here for guide (note pin on the LCD board with arrow mark is pin 1 and is the incoming DC power supply line): http://s807.photobucket.com/albums/yy352/budm/LCD%20panel/?action=view&current=DSCF0881.jpg
You may also want to look for bad caps (bulging top) on the logic board. There should be 5vdc feeding the logic board also.

Laptop LCD screen turned completely white
What can you do if the laptop LCD screen turned completely white? From my experience I can tell that this problem may be related to the following:
1. Loose connection between the video cable and the LCD screen.
2. Defective LCD screen.
3. Defective motherboard (I assume the graphics card is integrated into the motherboard).

When you turn on the laptop, it starts but the image on the screen is completely white right from the beginning.
Most likely you still can use the laptop with an external monitor. Just connect the monitor to the VGA port on the back or side of your laptop and then switch the video output from internal to external mode.
On Toshiba laptops you can toggle between internal and external screens using Fn+F5 keys. Hold down Fn and press on F5 until you get video on the external monitor.
On IBM laptops use Fn+F7.
On HP laptops use Fn+F4.
It’s possible that you have to use a different key combination on your laptop but you get the idea.
On some laptops, in order to be able to use the external monitor, you have to connect it to the laptop and then restart the laptop so the external monitor is detected by the laptop.
I noticed that in some cases the laptop screen may turn white because of poor connection between the video cable and the LCD screen. If you want to check this connection, you’ll have to take apart the display panel because the connector is located on the back side of the LCD screen.
I always check the video cable connection first. Reconnecting the video cable may fix your problem.
If reconnecting the video cable doesn’t help, most likely you have a problem either with the LCD screen or with the motherboard.
The best way to find out which one is causing the problem is testing the laptop with another working LCD screen. Without this test you’ll have to guess because as I mentioned before this could either bad motherboard or bad LCD screen.
You’ll have to disconnect the video cable from the LCD screen and the inverter board. After that you connect another working screen and test video.
The original screen is white but my test screen works normal and I can see the image. After this test I can tell that the problem must be related to the screen.
After I assembled everything back together and connected the original LCD, it’s still white.
CONCLUSION.
In my case this problem is related to the LCD screen and it has to be replaced.

Vertical White Band on LCD Laptop


Your new LCD is faulty. The band on your old one is the end of it I am affraid.
Laptop LCD's although built to take a beating (or so it seems) are extremely fragile. It only take a very small drop to end their lives.
