Audio problem: In the scene at Willard Whyte's house where Thumper and Bambi are fighting Bond, Bond gets thrown into 3 cylindrical statues. Just as the shot cuts, you can see the last column beginning to topple but there is no sound as it crashes to the floor in the next shot.
Audio problem: Peter Franks drives a Triumph Stag, which used a 3 litre V8 engine and had a very fruity exhaust note. Unfortunately this was dubbed over with a rather weedy 4 cylinder engine sound.
Audio problem: In the final scene, Mr Wint and Mr Kid bring in a dinner trolley. When Mr Kid places the desserts top over the bomb, we can hear the timer ticking. Yet, when the dessert is thrown and the bomb is revealed, the ticking cannot be heard.
Audio problem: When the man at the very start is being interrogated about the location of Blofeld, he says "Ciaro", but his lips don't move.
Audio problem: When Bond is driving away from the 'Moon base' his tires are screeching. But the asphalt is very rough - maybe its even gravel - so it couldn't make such a sound.
Audio problem: When James Bond is collected on the airfield they are all getting into the car. You see how the right door is closed but you never hear it.
Answer: If you mean by hiding - why is he never seen normally - then it's because he is a recluse and doesn't like to be seen in public (like Howard Hughes was). If you mean by hiding - why was he not seen during the movie - then it's because he was being held captive by Blofeld and his minions. Spectre didn't want him out and about ruining their plans.
