Good Afternoon, chedder:
The distortions you describe indicate a color purity problem with the set which may have been a result of the move.
Television sets are sensitive to magnetic fields as you know (you spoke of speakers). Moving the set across the planes of the earth's magnetic field (moving the set from one point to another or simply rotating the set)will cause
the screen to become magnetized and distort the color. Usually, the set will take care of this problem with its own internal demagnetizing system. The system operates briefly when the set is turned on from a cold start. It may, however, have become inoperative. That calls for a repair at the shop.
One of the "quickie" fixes we old guys used a lot was to take a Weller Soldering Gun (or any soldering gun), plug it in, lay the gun next to the screen, turn it on, rotate the gun in clockwise circles in the affected area, (at the point where the soldering tip heats up), move the gun about three feet away from the screen, and turn it off.
If the problem was a magnetized spot, this will usually remove it.
Purity (the set's ability to reproduce a pure color across the entire screen) is a preset commodity that is a function of position of the deflection transformer (yoke) on the neck of the picture tube. The yoke is positioned at a precise point on the neck of the picture tube so that the electron guns fire their beams of electrons at a precise point on the screen. If the yoke is misaligned, a red gun could send the beam to a green spot on the screen. Hence, the set displays in impure color.
Depending on the manufacturer, the yoke is positioned at the factory and could either be clamped on the neck of the tube or glued on the neck of the tube. Clamps break from age, glue ages and becomes brittle from heat. Move the set and jar it just right, the yoke may work loose and slide out of position on the neck of the tube.
All of this is fixable, of course. You can find out more about these little things at a very good repair site:

Get estimates! Don't put a lot of money into an older set.
New ones are not that expensive these days.
