    i have the acoustic solution 32" lcd model. same problem, i have heard very loud cracking noises and the picture flickers every time it does it. it is about 6 months old



    is this just contraction and expansion within the casing?

    I have a 42" LG LCD TV that when its on or off makes this very loud popping noise. Nothing happens with the picture and it doesn't do it all the time, but the times it does do is just very random. There shouldn't be anything wrong with the TV as we've had it for less than a year.
    This seems like a problem with all LCD tvs, hope someone can help.

I wouldn't recommend doing anything yourself because you can easily make the problem worse. I would recommend calling samsung because it's been under a year and see if they cover the problem. If you open the tv, that could void the warranty so I would try samsung before doing anything to it.
