Has anyone conducted a poll of failure due to this, or are we touching on the realm of paranoia ?
Not paranoia, not without precedence - room-sized projectors for sales and technical presentations work the same way - a high intensity bulb powers the projector, and you can't just shut them off, the fan stays on longer to cool off the bulb.

The high-end audio place where I bought the TV noted the need for battery backup, and what I consider to be a flaw in design - at the volume they buy, what would it have cost Mitsubishi to insert a component that would power (JUST) the fan long enough after a power-out to keep the bulb from frying? $20? $50?

Also to clarify - my APC unit is NOT the surge protection - the Richard Gray 1200C does that - I ONLY inserted the APC unit for its battery back-up, and do not believe it affects the quality of power to the TV - since the RGPC has already cleaned it up before APC gets its hands on it - power goes from wall==>RGPC==>APC==>TV
