First of all, I assume that your new LCD screen is compatible with theold one. Different screens require different video cables. Make sureyou new screen is compatible with your laptop.

What is your unit? If your unit is a laptop ou need to follow this.
You replaced the broken LCD screen in your laptop with a new screen. Does this sound like your problem? Let’s find out what could be wrong and how you can fix it. First of all, I assume that your new LCD screen is compatible with the
old one. Different screens require different video cables. Make sure
you new screen is compatible with your laptop. OK, let’s say you accidentally damaged the LCD screen in your laptop. A
part of the screen still works fine but you cannot use it like that so
you decided to replace the screen yourself.
Her is some instructions to follow.
Before you start to panic, check all cable connections again. Check
connection between the video cable, LCD screen and inverter board.
Reconnect cables just in case.
Take a closer look at the connection between the video cable and LCD
screen. It’s possible you accidentally pulled the video cable from the
connector during the screen installation.
The video cable has to be seated properly, all the way down.
Also, on some older LCD screens there are very thin pins inside the
connector. Take a look inside the connector, make sure there are no
damaged (bent) pins.
You can straighten bent pins with a very small screwdriver but this procedure requires a lot of patience and concentration.
Fortunately, most newer LCD's have a different type of connector, without fragile pins inside.
OK, you have reseated all connectors and cannot see anything wrong but the new screen still is not working. What’s next?
Remove the new screen and connect the old one. If the old one works
properly (except the damaged area) but the new one is dead, apparently
the new screen is defective and has to be replaced. Hopefully it has warranty.
Here’s another scenario. The new screen kinda works. You can see a very faint image but there is no back light.
If that’s the case, disconnect the new screen from the inverter
board and plug in the old screen instead, as it shown on the picture
below. If the back light inside the old screen lights up, apparently the
new screen has defective back light lamp and has to be replaced.
measure the heigth and width of your screen I have a source that has numerous used screens for projection sets both widescreen and regular. I should be able to help you out new screens are expensive and almost impossible to find used.
