I dropped my 27in phillps magnavox

if this is a distorted kind of rainbow aura affecting the colour, you need to de-gauss the screen - a good tv repair man will have the mains powered magnet to fix this - and shouldn't charge alot.

Sony Trinitron Color Rainbow

Usually when a tv is dropped the phospher screen inside the picture tube will detatch making the rainbow color This cannot be fixed as it requires changing the picture tube. Only other thing is demagnatize it with a demagnitizing coil (used by tv techs) but not likely to fix it since it was dropped. You have a bad picture tube.

Line across top of screen

If the picture is ok otherwise then only thing that probably needs to be done is a vertical height adjustment. That is if the lines never changes position from cold to hot.

Problem with picture

Did you hear the familar HUMMM when you turned on the TV? This hum is the internal degauser and if it's not comming on then there is your problem. On most TV brands you can use an external degauser ring o take care of the issue until repaired but, DO NOT do this on a Sony as it will actully damage the CRT.
