Dell Latitude D505 half of screen is black with colored vertical lines.


Sounds like you have a section of dead pixels. This can happen if the laptop has been dropped a lot or stepped on or some type of impact on the laptop. This is a hardware issue. You will need to have the screen replaced. In my opinion, by the age of the laptop, its better off getting a new one.

I have a thin horizontal line across my dell latitude laptop screen


If the thin line is always there, you have a set of pixels burned out. This usually occures vertically. There is easy fix, except to replace the screen. If the laptop is under warrenty, contact the manufacture for repair options.

Sorry could not be something easier for you.

Hi

Both Dell Part numbers 18THT and 5W299 are 8X DVD-ROM Drive Modules. DPN 18THT is compatible with Latitude C series and DPN 5W299 is compatible with Latitude D series. The two drives have different and incompatible connectors.

Your Latitude C640 is a C Series Latitude. You can therefore not use DPN 5W299.

If you need a DVD drive module, get DPN 18THT or an alternative Latitude C series drive.

Red vertical lines appear, can only run computer in Safe Mode


check the video cable and see if it;s properly seated. run the laptop with something that uses memory. if the video chip it going to show signs of problems, it will be more prominent when the laptop gets hot. most cases laptop motherboards have integrated video cards and cannot be replaced.
