Is there a repairable part in this light, or does the whole fixture need to

Thanks.

Might be the ballast. Might be poor lamp sockets. Both might be found
at your box store. Check prices vs. replacing fixture, then decide.

Or the switch on the wall. *Or the breaker in the basement.

One thing sure, four tubes didn't reach end of life at precisely the
same time.

Assuming the light fixture is somewhere in North America/Mexico etc.
AND, unlike some European fixtures, is of the type that does NOT use
starters.
Agree: Unlikely all four tubes fail at once.
As suggested by others; sounds like something affecting the whole
unit. Bad switch (Note 1), blown fuse/circuit breaker, broken wire
somewhere, etc.
If it does become a matter of opening up the fixture it may be found
that there are two ballasts; one for each two tubes. That is more
likely than one ballast for all four tubes. It is unlikely also that
both ballasts would 'blow' at once, although it is possible if there
was some sort of electrical surge. Or perhaps a bad neutral connection
somewhere?
Also if does become a matter of repairing the fixture it may be just
as well to replace if cost of labour is high? Retain the fluorescent
tubes they may have much life left in them.
Note 1. Switches that turn on and off fluorescent lights may in
certain instances suffer more wear and tear internally because they
are (compared to plain old light bulbs) switching an inductive circuit
Note 2. We have repaired numerous fluorescent fixtures, including the
newer 'electronic types' but it requires electrical knowledge, proper
tools and spare parts.
More so than any other fixtures, IMO, fluorescent fixtures need to be
worked on by someone who knows what they are doing.
