Here's a link to a tutorial on this subject from Hewlett/Packard:http://www.hp.com/ergo/precautions_e...elevision.html
And on the subject of protecting expensive equipment, besides living in the lightning capital of North America, Florida, (we really are!) we share another potential threat from our electrical service providers in the form of spikes and surges. As one of at least two individuals here in Lake Worth who's identical Zenith IQB64W10W HDTVs (mine is serial number 16, the other guy's is serial number 3) was damaged during Lake Worth Utility's infamous transformer episodes last summer, I'm going to put the Zenith and everything else in my AV system on UPSes.
Thanks for the kudos on behalf on the WPEC Engineering Department (I'm just a knob-twirler/button-pusher in the Production Department but the engineers monitor this thread and I'm sure they are grateful for your appreciation of the hard work that they continue to put into this project!)
