Tv picture colors are all wrong.

Sounds as if the tube has become magnetized. If you have access to a De-magnitizing coil this is a simple fix. Usually what will cause this is a lightning strike near-by or a magnet to close (such as speakers). Most TV shops have one of these and will possibly let you borrow it. If you get one, plug it in and wave it close to the face, along the top and sides. Trick is, get the coil about 10 feet from the set before you unplug the coil. If you don't it won't do any good. Good luck.
