My TVs are all old enough that they don't even have the adjustments you've tried. But one thing to look for. CRT televisions are vulnerable to magnets. Do you have any large speakers nearby? Magnets screw up CRT colours.
Unfortunately, this can't be fixed without replacing the picture tube. The drop caused a piece called the shadow mask inside the tube to warp or break loose. When that happens, the red, green and blue beams in the tube don't hit the right places on the screen. There isn't any way to repair this kind of damage.
If you had professional movers doing the job, their insurance should cover some or all of the cost of repairing the TV (replacing the tube, that is) or replacing the set. I wish I could give you better news.
what you are describing is a degaussing problem. It normally occurs if some Magnetic source has been brought close to your TV. Perhaps you have shifted your TV from part of the room to another? Or to another room? Did you or someone place a magnetic source (Speakers, Tape recorder, Walkie talkie, some toy of your children, etc near or on top of the TV? Just remove it.
And wait for a few days. The problem will get automatically cleared up, as the TV set's Auto Degaussing circuits will clear the color patches.
If it is truly a 52 inch standard projection set (you have it listed under 32V420T which is not a projection TV) and your 3 colors (red, green and blue) are no longer lining up and are all curved on the sides, then it means that your convergence power supply has stopped working. Post the actual model and chassis number and a better description of the picture here and I will be able to assist you further.
sounds like you have a deguassing problem with your TV .. have the repair person bring out a deguassing coil and see if thsat helps.. This will only be a temp repair as you will have to have the problem that caused this to be fixed. good Luck
