I have under-cabinet lighting, traditional fluorescent tubes. One of
them lights up at the ends only. I've tried removing and reinserting
it, with no improvement. There's no audible buzz or hum. The
fixture takes only the one tube.

Tried a lamp from one of the other fixtures? That's a quick way to
determine which is at fault.

Thanks, Gary. Yes, I did try another tube; I should have mentioned.
Result was the same.

Is it likely to be the ballast, or something else? And is the
ballast that little silery-metal cylindrical thing, about an inch in
length and maybe 3/4 of an inch in diameter?

That's the starter; some older fixture had separate starters, virtually
all larger ones have the starter built into the ballast.

Thanks. I had never heard of a starter before! With that hint, I
found this nice troubleshooting page:
