If it just started happening, there may be something with the internal board or speakers. The best thing to do is to schedule a service for the unit.

Hi,
I've recently been hearing a pretty loud popping sound coming from my LNT3242H tv. I've haven't noticed any pattern to it, but in the past few weeks I hear it probably 1-3 times a night (say over a two hour period or so). I've owned the TV for about 7 months now (but it was a refurb). I think the popping noise is new, at least I don't recall hearing it before. It's currently hooked up to cable directly from the wall (ie, no cable box). Any info as to what might be causing this and whether I should be concerned would be much appreciated.
Thanks.
