You have shown the antenna and downstairs TV are good. Something you

all four down cables shouldn't fail at the same time.
You'd really have to work hard to make a passive splitter fail. I
guess applying 110 volts might do it.
Lightning kills them by the millions. As an engineer for a major
CATV MSO years ago, I lost hundreds every month. They are simple three
port RF transformers, wound with wire the size of a human hair.
The inline amp may be
needed to overcome the loss of a 4-way splitter but you should see something
without it.
That might have been true in the old days, but with tv's going blank
if the signal is too weak, I wouldn't count on it.
I hope the house wiring is RF and not fiber-optic!
