Hi all, I accidentally plugged in my plasma TV from the US in Hong Kong and it worked fine. I didn't realize my mistake until later. Does this mean the TV will work fine or does it mean I got lucky and it may blow up if i plug it in again?

Well, a lot (most?) LCD and Plasma TVs have universal power supplies, meaning they can use any current from 110 to 240 volts.
On the back of your TV, there is an information panel/sticker. It has the electrical data. My guess is that it says something like 110-240v. If that is the case, go ahead and use it. You can either use a plug adapter or buy a cable with a HK/UK style plug.
Further, many (most?) flats can also work off any broadcast system (NTSC/PAL/SECAM). The whole HD revolution is making those a bit obsolete anyway.

Sorry I should have said. It says 120 Volts on the sticker. Not 110-240.

Hmmmm. How mysterious.
My wild guess here: The power supply is actually 110-240 but labeled as 120 only. Electronics parts that don't pass certain quality control tests are frequently labeled as lower performing parts. As in "yes it can handle x but not y, so we sell it as handling x only".
I don't know how I would feel about using it at the higher voltage. You could be looking at overheating and fire after a while. Of course, it could also work for 10 years without a problem...
