I'm having a similar problem with my MK4 cabinet too....I don't have the diagonal lines, but the "squiggles" every so often. They seem to diminish a bit after the cab has been turned on for awhile, but just when you think they're gone....they come back. I'm stumped, I've tried adjusting the focus and screen knobs on the flyback transformer too.....WTF!?
Very difficult to see the problems in video (as it always is). I had a pretty bad waviness in my MK2 when I bought it 2 years ago and a cap kit fixed it right up. Diagonal lines? I think sometimes the "raster lines" are visible if the "Screen" adjustment on your flyback is a little too high. Try turning it down slightly to see if they go away.
