wavy lines left screen

[timmy]

hi all, i have small wavy lines on the left side of screen while i cannot converge those colors there only about 1 inch long and goes top to bottom of screen. the picture cannot be centered because the left screen is not there,although i can center it but will be to far to one side.these wavy lines you can see the different colors are separated but the rest of the screen is fine, converged. any ideas what this may be, a cap or resistor in the yoke causing ringing in the yoke.
