I have an Inspiron 600m which I have been using for two months.  Recently, I started the computer and in the center of the monitor there were a number of different colored lines running vertically from the top of the screen to the bottom in a space about 1" wide.  There are also white blocks running horizontally out from one side of the vertical lines in a space about 2" wide.  The remaining half of the screen is usable, but this t-intersection of lines makes the other half basically useless (although I can still see most of the screen on that side).

There is nothing noticably wrong with the screen when the computer if off, but the lines are there when the computer is booting up and regardless of the screen setting.

The laptop has not been dropped or hit, but it has been exposed to some pressue while resting in a full laptop bag.  Also, I can see some sort of "sunspot" where the lines intersect; the bit of research I've done leads me to believe this is a polarizer dent, since the screen is not cracked.

Is there anyway to fix this problem that doesn't involve spending extraordinary amounts of money to have the LCD replaced, especially since I don't have "Complete Care" coverage?  I've gone to a few computer websites that seem to believe they can fix this sort of problem (as opposed to an unfixable cracked LCD).

Thanks for any help!
