Re: red thin line across the screen
You could reinstall the video drivers or get updated video drivers to see if this corrects the problem. If it only happens with a movie and nothing else it may be the software you are using to watch the movie may need to be updated.If possible try a different program or DVD to watch to see if it is a program problem or DVD problem. I always tell my customers to go to the manufacturer web site and check what updates they have for your model laptop. They usually have hardware and software updates to fix known problems. I hope this helps.

From the description the LCD screen will need to be replaced, first! hook a spare monitor to the video output on the back, if picture okay! the problem is the above mentioned, but if both screens show the same symptom it is the video graphics card.
That cannot be repaired as the screen on your notebook has layers and between those layers gas is compressed within thin columns. In your case your screen got a minute leak in one of the columns and now that column is unable to produce image. Hence, It can't be repaired. You have to change the entire screen.
The normal cause of lines across the LCD of a laptop is a damaged video
cable. The unusual cause would be the video card itself.
To determine which item is at fault, you need only attach an external
monitor to your laptop's video-out, and then swap your monitor view to
'both' or mirrored (usually just the function key (FN), plus one of the
Fkeys...look for an off-blue picture of a monitor on the Fkeys).
If the lines across the screen also appear on an external monitor, then the video card is damaged.
If the lines only appear on the laptop's LCD, but not the external
monitor, then just the laptop's internal video cable is damaged.
Try connecting an external monitor to the Dell Inspiron 9300 and see if the vertical line is also present on the monitor. If the monitor display is fine, then your laptop’s LCD display panel is defective. If the monitor also displays the vertical line, then your problem is with either the video card or motherboard located inside your laptop. Not sure if the Compaq Presario has an external monitor plug, but if it does the above procedure can be applied to that one as well.
