Thank you for the step by step instructions for disassembling the screen on Latitude D620, those photos helped me much, and I was able to repair the laptop for one of our beneficiary teachers from a school in Entebbe, Uganda. Kind regards, Daniel

In reply to Sudheer. @ Subheer, This sounds like a problem with the graphics card. To confirm that you'll have to test the laptop with an external monitor. If the same problem appears on the external screen, most likely it's failed graphics chip. In this case the motherboard has to be replaced. Also, try removing RAM modules one by one. It's not likely but possible you have a problem with RAM.

Hi IML Tech!

Thanks for the help with the replacement of my LCD screen. My computer is up and running again! However, the picture on my screen is grainy. I ran an update for windows and I also looked at my graphic properties. Currently they are set at 1024 x 768, 32 bit & 60 hertz. Is there anything I may have missed to make the picture clearer? Could I have damaged the screen during installation that would cause this?

Please let me know.

Thanks again!

Todd

In reply to Lisa. @ Lisa,

My daughter dropped her Dell latitude D620 and now the screen is black. i pressed a key (not sure which one it was) and the Desktop showed for a split second. Does that mean that the screen is still ok or do you think I need to replace the screen?

Most likely the backlight inside the LCD screen is damaged. If that's the case, you'll have to replace the screen.

In reply to Eric. @ Eric,

I didnâ€t completely reattach it (put all of the screws back in) to test â€“ would that make a difference?

No, that wouldn't make a difference. As long as your new screen and inverter connected to the motherboard it's not necessary to assemble the laptop completely for test.

Replaced screen and inverter, but screen is still black.

If we assume that new screen and inverter are good, your problem could be related to following: 1. Bad connection between the video cable and screen/motherboard/inverter. 2. Failed video cable. 3. Failed motherboard. Could be just bad video connector on the motherboard. Sorry, I cannot tell what is wrong without testing the laptop with known good parts.
