I assume you mean your TV box and not your TV itself.
If so, which box do you have?
Did you previously get the missing channels?
What have you tried to get the channels back? A retune? A box reset?
What happens if you plug the aerial directly into the TV bypassing the box? Do you get all channels on the TV or is this experiencing issue too?
Have you checked the Freeview website to see if there is any engineering works taking place on your local transmitter?
If you can let us know we can advise further.
Thank you.
