I'm trying to fix a ladies laptop which was dropped on the floor, and I think (hopefully) that all I need is an LCD replacement screen.

The laptop turns on fine, I can hear the windows loading chime while it loads up, and the hard drive light flickers. However, the display doesn't show much except a greenish-bluish color with lines going through it. The backlight does work though. Now, I'm hoping all it needs is an LCD replacement screen to work.

This is what the screen looks like while the laptop is on: %5b/URL%5d"> .

I think the graphics card in the laptop is working too,because when Windows is booting up (I know because of the chime) the screen kind of changes colors a bit.

I'm not very good with laptops, but I think this is all I need. I opened it up, and replacing the screen seems easy enough. I also checked all the connections, and they seem to be secured snuggly.

I tried my tv and it didn't work (using VGA). i just tried a computer monitor and it didn't work wither (VGA also). However, this time the laptop made a sound like a new device was detected. Since I can't see anything on the screen, it would be hard to go into display properties and select a different monitor :thumbsup: .

Do you think If I disconnected the laptop display, it would automatically go to the external monitor?

No, it will not go automatically to the new monitor, because the laptop doesnt know you dont see a thing on the laptops LCD. For as far as your laptop is concerned, you use your laptop screen.
I have had for years a laptop (toshiba) with an external monitor. I canged my settings so that if the monitor was hooked up, the laptop would use it. However, I had some sort of button with which I could switch manually. I recommend you to read a manual if you have it.
If you can provide the make/number, I can look it up, most manufacturers have their manuals online.

regards, Elise

I disconnected the laptop screen, and this time when I started it up, it did display on the external screen. It showed the Dell start up screen, and then Windows loading, but, of course, once Windows booted, it no longer displayed (I'm using a 15" monitor with a 1024X768 resolution, while the laptop is probably using a widescreen resolution). The laptop is still working though, because it makes the Windows chime noise, and the hard drive light is flickering.

So, it must be the display. I found a good replacement from a reputable seller of lcds for only $56.XX! I was expecting something like this to be $100+. Then again, if there's a surplus of these older displays, they probably want to get rid of them. It's a Dell Inspiron B120 if you wanted to know.

Thanks for the feedback :thumbsup: !

Jump on that. I usually figure $200+ for a replacement LCD in most cases. Hope the repair goes smoothly.
