Can it damage a projector, YES of course, carefully moving a projector and barely bumping it can damage it if something is loose or poorly constructed. No projector is EXACTLY the same in regards to the ability to take sound waves or shock waves. I never said it was impossible for it to damage a projector, I said it MIGHT damage something on certain projectors, but it is doubtful it will damage the IC's.
DGP always gets a big ego if anyone disagrees with him, it will suddenly be everyone elses EGO that is at fault rather than his own. I am personally tired of his "underhanded" comments directed at people, as if no-one has the right to voice an opinion on a subjective matter, and he is the only opinion that matters...
Will it damage a projector, MAYBE, but then just get a good warranty. Everyone in here is acting like a know-it-all right now because no-one actually knows the specific limitations of a specific projector. I would surmise however that in most cases, many projectors will keep going out of focus (some with tight lenses may not) before damage occurs. What I am saying is that more than likely you will notice other side effects before the force is strong enough to damage the projector, but of course there is no absolute guarantee.
Also, the sound waves required to damage a projector (unless the PJ was very close to the speakers) would likely vibrate the mount so much that the first side effect noticed would be a SHAKY image. I am just saying that you will probably ruin the viewing experience before you even get to the point of damaging anything, ok even this isn't guaranteed, but it makes some sense.
I don't know the specific levels it MAY or may not damage a projector, neither do any of you, but what I can tell you is that it is unlikely to damage the IC's unless the boards are severely warped or cracked. How do I know, because I've seen enough electronics beat up and dropped to know this, after 20 years of being in electronics, and I've done it myself on old boards. Scratches or cracks are really bad for electronics because it will break the connection of the soldering points on the boards, but evenly exerted pressure (even applied at large amounts) or blunt force or vibrations, well then it is usually not nearly as sensitive to that (NON-SS can be, but I am talking the IC's themselves).
I've literally thrown electronics down the street and played baseball with them and plugged stuff in after doing so, some things still work, some don't. You can bang some of these electronics across the wall many many times before they break, but as far as will it damage a projector, MAYBE, no idea how much BASS we are talking, but it is unlikely to damage any SOLID STATE PART. Of course if you bang it against the wall, it might break it right away even from mid-level force, but it just depends on the angle and how you do it. So the same rules apply to all blunt force, depends, it could. The vibrations very well might affect the lamp life, but then again I don't know the specific levels at which this occurs.
