This sounds like one of the convergence IC's has cracked loose or burned out, and should be replaced and realigned by someone with experience.

Red and blue overlap shadowing

Sounds like a convergence ic problem, normaly i tell people to replace the ic's but in your case try to re-solder the pins on the ic first, you may just have some pins broken loose from the board. Locate the stk392 ic's there will be two of them located on a heat sink, unplug the tv and get to the bottom side of the board and re-solder the pins. if this does not work, then replace the ic's

TV shows large red spot in middle of tv when dark show are on, you can see it more.  Now blue spots on upper right side too.  Spend way to much on this tv to have these kinds of problems only after 3 yrs.
