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.

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?
