    You need to change it as soon as possible.

    I had a flat panel LED 32inch Westinghouse that did that on cable but was fine on antenna and it wasn't fixed when I sent it back for Westinghouse to repair it, and it was proven to be an incompatibility with two frequencies. They have gave me the runaround up until I finally got a gift card with the money I bought it on it and went out for a new set.

    In my case it was a design flaw in the tv.

    May be because of speaker problem.

    if you have an older crt,try removing the housing from the main set w all the wires & adjustable pots (= potentiometers),lightly shopvac as much dust as you can reach ( power off meanwhile),use a hand mirror after spraying a bit of non oil based tuner cleaner into each pot receptacle,,twist each one,,might be a couple dozen you can adjust,back & forth back n forth.

    and some pots are offset allen type hex metal twist thingies at the side of the set,,some of these you can twist by fingers,

    clean the plastic housing too..wipe with windex type cleaner.

    turn the set on,,pic might be scrambled,go through each pot you cleaned,twist all of them checking the mirror for the effect,,also the spin color slot shaped adjusters at the skinny base of the glass tube.

    tinker until you get nice tones & colors,,off a good quality dvd put on freeze frame,crackling sometimes is because of static electricity that periodically discharges,,grounding the chassis might stop this.

    you have a weak signal.... less than the minimum amount.

    If the sounds are physical (from the cabinet),

    they are most likely the result of thermal expansion or contraction.

    Nothing anyone can do on purpose will stop them.

    If the noises come from the speakers, they could be caused by the TV,

    in which case a repair shop should be able to deal with the problem,

    or by a signal source (network or local station),

    which no one can do anything about.

    A third possibility is noise and transients on the power line.

    You can try a line filter, but if it isn't a good one

    it may have only a minimal effect, or none at all.

    TrippLite makes something called an "Isobar" outlet strip.

    If you use the outlets filtered to 80 or 100 dB,

    there should be virtually no pops from transients.

    Most commonly caused (especially on cheaper brands) by simple thermal expansion and contraction. All TVs do that, but better quality construction and design reduces the possibility of thermal noises and also adds compliant bushings and acoustic dampers to parts which may move against each other in that way. Also extra fasteners and clips to hold everything more firmly in contact.

    Because sometimes TVs mess up, too!
