Roundie left edge purple

[DaveWM]

its about the very 1st 3/4 in a very straight vertical purple edge. Since its on the edge its only show about 6" beyond that on the top and bottom the crt curves and it does not show. The purple is straight that is, it does not curve with the tube.

Tried deqaussing, no help. I tried taking a pic put it is too faint to show up.

It also seems the width is underscanning as the screen seems to blank out at the extreme left edge, maybe the 1st 1/4 inch from the extreme left, the the purplish hue for the next 3/4 the fine. You can see the picture thru the purple hue.
