The replacement will be relatively small (22-inch or so),

Another recommendation to go for a (much) bigger screen for viewing
(espec. captions) and hearing.

It can be v hard when people resist a TV they think will dominate the
room. But I can't recommend from a sample of only one the tactic of
getting the (cough) wrong one delivered just before Xmas and explaining
they can't swap it for a smaller one until after the New Year holiday.
