Speaker rattle on a widescreen tv

    I have a Philips 32" widescreen tv, can't remember the model, it's about four years old. It's on a wooden tv stand, no extra speakers connected.

    Whenever there's a deep bass on the soundtrack i.e thunder, loud orchestral soundtrack etc., the speakers rattle very noticeably on both sides. I tried putting something soft under the tv to seperate it from the wood, this reduced the problem a bit but it's still very noticeable.

    Anyone know if this might simply be a matter of too much volume or bass, or is it a fault with the tv speakers themselves, necessitating a repair?

    Has this always happened or is it just a recent occurence?
    Sounds to me (no pun intended) that the speakers can't handle the bass.

    As far as I can remember it's done it for a couple of years now, don't think it did it right at the start but can't really remember that far back :)

    Strangely some DVDs like The Matrix are fine at a given volume, but play something like Raiders of the Lost Ark at the same volume and it's rattle ahoy.

    Still, thinking of getting a new Panasonic 100hz tv and 6.1 surround so might settle for that way of solving the problem :)

    you might have a standing wave (basically the physics of the TV and/or stand and/or room result in certain frequencies being amplified- hence the variance between DVDs you've tried).

    putting speakers in a corner will amplify the bass - if the TV is in a corner then chances are the speakers will have a greater

    also the speakers might be loose - one or more of the fixing screws inside the TV might not be secure - fixing this yourself would probably be dangerous (I recall someone telling me about large capacitors with charge of 240+ volts) and would definitely void the warranty

    of the three I suspect the first is your problem - see what happens when you move the TV into another place int he room - or better still into a another room. try using the same sequence on a DVD to do this test - should only take 30mins or so.
