Normal. Back then there was nothing that would give the
kind of signal that the OSD does so it wasnt a big issue.
Note the rest of the pix is good. When Zenith started using
comb filters about 7 yrs later ( M line IIRC) & you side
by sided them the difference was startling. I think about
75% of the customers spent the extra $50 to get it.
All but eliminated things like you see but also made a big
difference in resolution. Individual hairs could be seen instead
of a blur at best. You may not see it much on other older sets,
thats because they arent as good as yours.
A few things do improve with time........
