It's most likely a failure of the convergence amp and some other power supply problem in the convergence circuit by the sounds of it... Your unit takes an STK730-130 and some 750k 1/4w resistors for the yoke return. I would bet two or more of them are out of value, at least R19702 and R19703... There are also two diodes Cr19710 and Cr19709. P/N# 164590 which commonly open under a load and are recommended to replace anytime the convergence amp is replaced. Also check Q19700 (Bc457) which crosses nicely to an NTE123a...
Not real expensive in a reputable shop - just a pain this time of the year.. I would recommend getting it repaired, it's worth it..

My tv is showing in 3 different colors red, blue & green. and it has three lines at the top of the screen in the same colors

It seems to be that your dmd board might be going out, let's do this go to the menu and if you still have those colors, definitely your dmd board is taking its last breath :P but if they're not there, the issue is going to be with your video board

I was just given this t.v because friends couldn't figure out what is wrong with itl. The colors don't line up right,looks kinda blurry depending on the lighting of the program being watched. How do i fix...

According to the manual:
1) go to the "TV Main Menu"
2) Select "Screen"
3) Select Adjust Projection TV (obviously only if a projection TV).
This then allows you to adjust the TV's 3-colors. Selecting GREEN CENTERING brings up a control panel that lets you center the green projection tube on the screen. Selecting RED CONVERGENCE or BLUE CONVERGENCE lets you align the Red & Blue projector tubes. Centre the green projector tube 1st. Then adjust the red & blue until the test pattern on the TV screen appers white.
Good Luck!

This is a convergence oroblem. First question is do you have the convergence option in under setup in the customer main menu?... if you dont you may have the very common fl231 fuse problem; i have wrote a article on this under the tips and tricks section. this is a very simple inexpesive repair. If you do have the "convergence option" then you may have to replace one of three cuircit boards
