You can have that kind of selective effect if the signal is a bit
borderline or the dish is not far enough off-aim to stop everything.
It is easier to diagnose when using a normal satellite receiver which
gives you an on-screen display of the signal strength and quality; $ky
boxes only show the figures for the default transponder which can look
good while other transponders have much worse values. You could also
have a dying LNB (but check the aim first unless you have a spare LNB
to try) which is failing to work at all frequencies/polarities; that
can be checked by compared the good/bad channels against the lists at
e.g.
