Failure to "cooldown" has no impact whatsoever on the lamp, none, PROVIDED you don't turn it back on again right away. While the filament is still hot, it is most vulnerable to a failure if another "start-up" surge of current is allowed immediately to spike thru it again. That would be a Bad Thing. But most projection products endeavor to disallow this anyway w/internal timers.
The hot lamp's failure to complete its cool-down cycle, so heat is allowed to build-up inside, could affect the product's internals, depending on the internals. Anything plastic nearby to the lamp is not gonna like it. YMMV.
