My LCD screen is only partially displayed. I have a black or sometimes blue or white area to my right side on the screen. When I press on the screen(Top just left of center-where the connector is), it sometimes resolves the issue and the full screen appears. Could this be the inverter board or the other board at the top of the screen where I press to get the full screen to appear. It appears at though the lcd screen is ok since it sometime shows a full screen. This happens at start-up. Usually when the full screen appears it remains for the time that I have the laptop on.
I also have a light blue streak just left of center that is about 1.5 inches. This never disappears.

Re: LCD screen partially display's
This kind of issue is usually due to a loose inverter cable, re-seating the cable is a relatively simple matter. If the laptop is still under warranty you should contact Dell to have it repaired, if on the other hand it is out of warranty you should shop around for a repair quote unless you are absolutely confident you can strip and reassemble your laptop.

Your screen is shot or partially disconnected. A lot of laptops have the vid card to lcd connect in bracket that connects the screen to the keyboard. I have fixed many by siimply taking it apart and reconnecting the clip but the spots dont sound good. Ebay to buy one or Cl to dump it as a fixer. Either way its a waste of money to have someone fix it for you unless you do it yourself.
Your lcd screen has gone bad and needs to be replaced. To isolate that it's the screen or the video card borrow a monitor from a relative, neighbor, friend or co-worker and plug it into the laptop. If the borrowed screen displays fine without any problems then your original screen is bad. If the borrowed screen shows the white area with black leakage ink as your old monitor then the video card in the computer is bad.
Plug in an external monitor and see if thedisplay shows up on it. It can be any kind of monitor even the old big fat crtmonitors as long as it has a vga cable to connect to your computer's vgaport. If so that proves your video card is ok. The video will showon most systems when you reboot without you having to do anything. Some systemswill require you to hit the FN (Function key) + F1 thru F12. Hold downthe FN key then hit the correct key for displaying on the monitor (F1 thruF12). The correct key will normally have CRT/LCD on it or it will havethe icon of a display.
In LCD screens is a common problem that after setting a lower resolution than recommended you'll see a black stripe sometimes up and right, right click on any empty spot on your desktop and select properties then go to display options and move the resolution bar to a higher point and click apply also click yes in the warning display and accept.
I'm sorry to say that you will have to replace the screen soon. That vertical black and white lines that appear is the early warning signs that your screen will soon go blurry, or have a partial screen, or have it just stop working. This happens from the many times the screen was lifted open and closed and the ribbon cables just need to be replaced. And since the ribbon cables can't be simply unplugged and then replaced, you will just need to get a new replacement screen.
