Please log in for more thread options Does anyone have any /actual/ experience w/ mounting an LCD flat-panel TV to a ceiling (yes, like in the old Philips commercial). I've been unable to locate a definitive answer on the topic, and would appreciate any real-world/actual comments on the subject. FWIW: the unit being considered is a Sharp Aquos 32" LCD display. Thanks | |||||||||||||

Please log in for more thread options Not actual experience, but one thing to think about ... I was part of a design team for a computer LCD panel. One of the things the thermal engineers forbade us to do was allow the panel hinges to allow the panel to be flipped horizontal, since it would collect heat. This model had no fan, and relied on the heat rising up vents in the top of the cabinet, and cool air replacing it below. So tilting it so the vents were all on the bottom, and having heat collect inside was strictly a no-no. It may not be quite as bad with your ceiling mount, since the vents will be on the top, but you still will lose the airflow across the panel. So the heat may get out of components directly below the vents holes, but other places will still collect heat. So if your models doesn't already have a fan to force air through, I'd add one to help out. Probably one or two small PC fans would be fine. Put them somewhere in the center where heat would collect, and orient them to suck the hot air out. Cool air will then enter from the vents on the edges. >FWIW: the unit being considered is a Sharp Aquos 32" LCD display.

The unit in question has two integral fans near the upper corners, so presumably heat would not be as much of a concern. Further, in my case, the display would be mounted at 5-10 degrees from horizontal, allowing for some natural convection (?). | |||||||||||||

Presuming the mounting hardware is sufficient to hold the unit securely... | |||||||||||||
