    While watching movies, the ceiling mount for my CRT projector crack, creaks or tings every few minutes. Its quite loud and quite off puttung. Is this normal or should I get it looked into?

    Is it made out of metal?? If so it will be the material expanding with the heat exhausted from the CRT

    Try put some lagging around it, to stop the heat bulid up, this will also deaden the sound if it still does creak. Or even divert the hot air from the CRT with a re-directed bit of pipe or something.

    Hi Richard,

    Not sure what it is, Roland put it up. I might have a play at the W/E to see if I can deaden the sound a bit.

    ...like a bell? Try Dynamat. Its a panel deadening material used in car stereo installations. You can cut it to shape and the back is self adhesive. Halfords sell it. You'll find Dynamat with all the speaker cable and poweramp accessories.

    Regards

    It's a feature of the 1209 I'm afraid they all do it. great when you are setting undernieth. should only do whilst it is warming up though. there are two metal plates in the projector clamped either side of the plasic casing
    Jeff tubes still oozing when warm I'm afraid.

    My 808s also cracks now and then. I have the plate mount. I thought it was a problem with one of my speakers when I first heard it and was about to jump up and start pulling things to bits. My wife told me what it was as she had tracked it down to the projector when I was working away.
