Ok, I know a dozen people here have said how easy it is to repair these
little buggers when they go out, so I figgered I'd ask. I have a
Chinese-made CFL18ROHS, Great Value brand (WalMart) 75w equivalent. How does
one go about opening it to R&R the capacitor that I hear is always the
problem? It lasted about 10 seconds..... There is a Radio Shack nearby.

Probably a Wal-Mart nearby too. Present the bulb to the return desk,
they will give you another hopefully good one, and save your solder
for another day.

I don't believe "easy" is the right word. "tricky" and "dangerous" seem a
bit more appropriate. A bulb drop-in replacement CFL is definitely at the
pinnacle of the "no serviceable parts inside" concept.

Normally it's just a matter of prying the case apart, as it usually just snaps
together.
That sounds like a random infant mortality to me and probably not a cap failure.
The
cap(s) normally fail after some use and heat soak. Unfortunately when the cap
fails,
the raw ripple makes the control chip do funky things that usually burns out one
or
both filaments. I've not had much luck repairing the things for that reason.
The
cap is a 105 deg C rated cap that you won't get at Rat Shack. Any lower rated
cap
will quickly fail.
