I assume this is a joke. Lamps go out because the filament eventually burns
through.




There won't be an incandescent lamp in a TV.

Cold cathode fluorescent lamps fail because the cathodes wear out, usually
the phosphor is depreciated by then as well.

UHP lamps in DLP and LCD sets fail because the quartz arc tube devitrifies,
they run about 3,000 PSI in operation and will fail catastrophically if run
too far past rated life.
