BBC4 HD is on a (time)shared multiplex with Cbeebies HD (which is on Channel 205).
BBC4 HD only transmits from 19:00 to 04:00 (and can't transmit a "holding" signal outside this, as Cbeebies is hogging the bandwidth).
My surmise (though it is only that) would be that the particular TV, when tuning, needs to see the channel active when physically tuning (i.e. when doing a set-up for channel numbers), and that set-up is not being done after 19:00, when the channel is broadcasting. (different TVs react in different ways).
If it can currently see channel 205 in its listings, I would be even more likely to think this is the issue.
If you do have channel 106 in the listings and tune to it before 19:00, you are likely to get a "no signal" message or similar.
Get him to try an auto tune or add channels after 19:00, when it should be able to see BBC4 HD.
Can't as yet account for your "News" issue; that channel is 24 Hours and not a shared multiplex.
