The TF saying nothing could get through their shields was backed up by a similar comment from Ric Olie. This was about the overall strength ( when active ) of the shield protecting the various parts of the ship from external attack. It didn't cover timing when the hangar shield would be down because an enemy would have no way to predict that. Not coincidentally, in the Battle of Coruscant at the beginning of ROTS, the TF ships are the only ones whose deflector shields can be observed visually as still being active
( through the use of a blue ripple effect, when the ship is hit by laser fire, which was previously seen in video games like Battlefront II but not used elsewhere in the films ).
