My two cents...
I wonder if the zebra striping is the burst being displayed during horizontal retrace? A good test is to adjust the horizontal hold: if the zebra moves in the opposite direction to the picture when you adjust the control, that is it.
Remember that in the pre-color era, this would not have been a problem!
Otherwise, the stripes may be due to ringing on the forward sweep. Since it is on the left, the trouble would then be in the damper circuit.

I saw the pictures again and see the zebra across the screen. I bet it is the color burst on the screen.
