The blank out are about 1mm in length at the same horizontal position where
the text would appear. I can fix this issue when I replace the A5 board from
my second scope. So the issue must come from the A5 board.
I find this intriguing: Are the readout excursions timed at constant intervals from the trigger event and at the exact moment the horizontal dot position is just beneath the readout? I don't think that would be desirable; a random interruption largely hides the gap, so if I interpret Bernd's description correctly, it would indicate a malfunction.
