You must get another scope and see if there are signals getting to the
CRT deflection plates when the input is grounded. Bad electrolytics
are the most likely problem!!! But, a scope is the only way to tell
for sure.

In this case shouldn't the distorsion be the same whatever the
y-position is ?

I have another scope (which I hoped to slightly upgrade), so I'll do as
you suggest and check the signal on the vertical deflection plates, to
be sure.
