Had the same problem. Fixed it though. Here's how:
You'll notice that the screen comes back to life if you press down on the very top of the green line. This is because a controller circuit board behind the LCD screen (at the top) is pressure fit flat-surface-to-flat surface to the contacts on the back of the LCD. Eventually, the sticky substance that holds this circuit board in place wears thin, collects dust, etc.. and the connection between the circuit board and the lcd contact is lost. The line appears where this break in contact has occured.
So, the solution is to increase the pressure at that point to reestablish the connection. I wasn't able to remove the circuit board to clean beneath it as it seemed too likely to cause damage. Nor would I have had the right adhesive to connect it back, so I simply removed the LCD and put a bunch of tape at that point so that it would "push" with a little more pressure when screwed back into place. Worked great.
To remove the LCD, pull off the 6 feet around the screen. Remove the screws behind them. Carefully pry off bezel with a small flathead screwdriver working your way around it. Once removed there are simply 4 screws on the left and 4 more on the right of the LCD to remove. Pull out screen carefully and start stacking bits of tape on the spot where pressure seems to work best. Put it back in and see if you've made any difference. I did this with the computer on so I could verify my results. Just be careful not to short out any naked contacts.
If this doesn't work for you, at least you'll know you just need to replace the LCD, not the video card. Easily found on ebay.

Bad LCD....need part# 441758-001 (LCD+Digitizer Glass), order from a company called Smart Micro in Dallas/Addison TX

The blob is a phisically damaged part of the LCD screen. Unfixable, the screen must be replaced and it will be expensive.

1. you can replace it with a new screen. (expensive)
2. have a technician to repair the board of the screen, the cable, the IC's, etc. (save you money but the length of repair is very long. maybe it will take a week or two.)
your choice.
