No, but I occasionally hear this on my 2yr old panasonic plasma in my BR.

I also experience the same thing with my 3 and half year old lg lcd tv ,I'm not sure if this because its already quite old or maybe its already have some technical problems, though its still working well. I also have a plasma tv with the same brand and it doesn't makes an intermittent clicking sound even though its a lot older...

I have a two Panny plasmas from 2006/2007 model years, a 42" and a 58" and they both do this. Hasn't caused any problems so far.

Speaker click or other?

In my case, it sounds like a relay click, the same exact sound that is made when the sets are turned on or off. I don't believe it has to do with heating up or cooling down because they will "click" when they have been off for days.

The 42" phantom clicks more than the 58", for what it's worth.

I don't hear any clicks while they are on in normal operation.

I have had a plasma TV for a long time and havent had this problem.
