Like some others, I'm not worried about the cost of a lamp, but since there
is talk of a backlog of orders for lamps for my set (G-series JVC) I got a
spare lamp just for peace of mind. Makes me wonder if the backlog is caused
not by lots of failures but rather by lots of people buying spares like I
did. That's the economist in me speaking ;<) ...

I've wondered about the idea that manufacturers could provide some kind of
simple power back-up for the fan. It wouldn't have to have much energy, just
enough to run the fan for a minute or so. What could it cost, maybe $10 at
the factory level? You'd think it could be made available at least in
higher-end sets. That would be a better solution than a UPS, since you still
have to turn the set off before the UPS runs out of juice.

Alternately, I wonder if a heat chimney could be built into the case above
the lamp, which would keep some air flowing by convection.

I guess the ultimate solution will be LED lamps, which run cooler.
