Have you considered going even simpler?
Put a reasonably bright light near the TV that is triggered by the doorbell
and phone.
You could even have different ones or different flash patterns for each
source.

Getting a little fancier, somone else suggested killing the TV sound.  If
you do that, you could have the circuit latch so that the sound stays off
until a button is pressed.  That way he can answer the appropriate thing
without the massive sound level and come back to it.

My mother likes the TV at a much louder level than some others do.  I would
consider setting something up with some sort of wireless speakers at the
headrest on her favorite chair but there is the problem of getting power to
it without the cord being a tripping  problem.
