I have a Dell Inspiron 1420, and recently my wife accidently dropped it and cracked the screen. I bought a replacement screen off of ebay and I installed it. Once I started the laptop, however, there was no video. The backlight came on while the computer was booting up, and then the screen turned dark once vista starts. It stayed dark for about a minute or so, and then it beeped once. It waited about 20-30 seconds, and then beeped again. It did this four or five times, and then the computer rebooted, and it did it all over again.
I have tried connecting an external monitor to the laptop, but the computer doesn't detect it. I installed my old screen that is cracked back into the laptop and the video works just fine, besides the fact that I can only see part of the screen. I can connect an external monitor to the cracked screen and it detects it.
I talked with the person who sold me the screen and he had me read him the part number off of the back of the screen. He then said that he would send me a replacement screen that was exact same model as the old one. I just got it today, and installed it. Unfortunately, it is doing the exact same thing that the other one is doing. Any help that you guys could give me would be appreciated.

Try to identify your beep code.
But to me it sounds like One Long and Three Short Beeps. Video (EGA) Display Circuitry. CH000607

I dont think that is the problem because it boots all the way into vista before it starts beeping. I know this because I can hear the login sound when it fully starts up. Also it isn't one long and two short, they are about equally spaced apart.
