Ok I have included some information that could be VERY helpful and given the correct credit to the original author. If you find this useful don't forget to rate the thread. Thank you.
SERVICE MODE WARNING:
Without proper documentation Don't mess around with the service mode adjustments unless you know what you're doing and have the service manual to guide you.
Once you enter service mode the first thing you should do is record all the original values BEFORE you change anything! - This is the only way to restore the television to its original (factory default) state should it become necessary to do so.
Then, bring up the cross-hatch pattern by repeated pressing of the TV/VIDEO button. You can then use the volume Up/Down buttons to change the PARA settings, this should cause the grid to bow in (concave) and out (convex). Adjust until the grid is the most linear.
The numbers 1,2,3,4,5,6 jump to different items. 9 displays SELF CHECK
The number 7 displays a grid. There's a blinking cursor in the upper left corner. The numbers 2,4,6,8 move the cursor. 3 cycles the colors (RGB), 5 stops the cursor from blinking, then when you push 2,4,6,8, you are adjusting the convergence at that point for the selected color. Pushing 7 again gives you a "warped" grid for a few moments. Pushing 7 again removes the grid from the screen.
If you're attempting to adjust color or geometry errors, you'll need the Video Essentials DVD, Laser Disc or some other source of test material.

I had this problem on a 37" Viewsonic LCD. Pulled it apart and through a process of elimination, I traced the problem back to a small board with several flat white ribbon cables coming out of it. The board was near the top center of the screen and under a ton of other equipment requiring almost a total disassembly.
This small board was clean but I noticed one of the rubber standoffs had slipped down and was making contact with one of the outputs running to the LCD. It also happened to be the output running to the section of the screen with the problem.
I postulated that the sticky glue on the rubber standoff may have just enough conductivity to cause a problem. Moved it so that it was no longer touching anything electrical and then reassembled the TV.
Afterwards, I turned it on and was pleased to see the problem has gone away! If you're having the vertical line problem, then maybe this could be your problem too, especially if you have a Viewsonic since it could be a manufacturing defect.

Hello; I am John at J. D. Electronics, Poland Maine. This problem is caused by a defective LCD panel. This part is very expensive! Aprox $ 1000.00 from Sanyo and less than $400.00 from Encompass Parts Inc.
