I have a MC33 also. That set has way too much width. If the integrators are bad, It (as mentioned earlier) will have stretched top and black at the bottom. If I remember right, that set width is adjusted by the blue yoke lead which goes to a terminal strip on top of the chassis next to the high voltage cage. If it is on the blank terminal, it is minimum width.
A crazy idea..... What is the line voltage the set is operating on?
I don't think the signal source is the problem unless its (a dvd source) aspect ratio is set wrong. It should be 4:3. Make sure it isn't in zoom mode.
These sets can have a great picture!
