It's possible your missing channels may be lurking somewhere under a different channel number - sometimes you can get the same channel on several different channel numbers. Check your channel list.

Could be that some of the channels have been changed from vertical to horizontal polarisation, have you checked what type of aerial you have, are your neighbours having similar problems, what type of aerial are they using, go out side & have a look.
I -- or X the X one will get the lot.
