    I have a Panny 53 inch. It does vibrate on hard bass hits pretty bad... How can I silence the RPTV? Any ideas?

    I believe you'll have to provide some more information.
    For instance, are you talking about the internal speakers causing this vibration?

    Do you have a sub?
    Is the TV on a stand?
    or is it standing on its own?
    Can you feel this with your hand?

    Is your sub touching the floor?
    Is the tv near a door?

    Are you playing the bass too hot?
    Does it matter? perhaps not.

    To all these questions you must attend
    Before illumination, we can send.

    Locate the offending panel(s) and see if you can easily apply some sort of damping material such as Dynamat. If its the top panel, maybe just placing something heavy on it might help. If it's from the center channel (quite common), isolate the speaker from the TV.

    Not internal speakers...

    Front stage:
    SVS 20-39PC+
    JBL S312II
    JBL S-Center-II

    The sub is on the floor next to the left of the TV. TV is also on floor.

    TV not near door.

    Bass is SPL configed to the rest of the system.

    It seems to be the back/top panel of the TV. The one that slopes downwards... Wonder what I can put on that...

    ok, no bad poems this time.

    is the back/top panel physically moving/flexing?

    are you sure the rattling is not coming from within the back/top panel?

    if it's the TV shaking against the floor, you might be able to do something about that. For some reason, rubber cement comes to mind, as it forms a nice gooey cushion that's easy to apply (and remove) that you can probably use to 'mount' your tv onto the floor. That might disperse enough energy to prevent the back/top panel from moving...

    EDIT: actually, the rubber cement thing probably won't work too well since you seem to have a heavy tv... so ignore that as a stupid suggestion. [​IMG]
