Thanks! I've located the mode switch and done some more tests (not
disassembling anything yet):
I can see the mode switch wheel is standing still when I am just
powering on the unit. Other wheels on the right hand side "below
the floor" move a little and then stop - the faint sound gives me
a feeling that something is stopping them from moving more.
When inserting a tape I can see that the mode switch wheel is
rotating.
A few times when inserting the tape the unit seems to do a more
complete initialization and the video head arms are moving, but
then I hear loud clicking noises as from two wheels sliding on
each other. I can see the mode wheel standing still but vibrating
in sync with the clicks, as if something that wants to move is
stuck. Do you have any idea why this happens, doesn't seem
directly related to the mode switch...?
I shot a video of this behaviour showing first the "direct eject"
case and followed by the "full init" case. Would you please have a
look at it?
