Panasonic projector lamp?
I don’t know that projector, and while it could be the bulb may be some other issue. Not much help so far … eh? Consider three things … first, 800 hrs is very low. 2000-3000 hrs is more typical (although bulbs can blow at any time … particularly if the projector is shut off before inadequate lamp cooling, subject to power cuts, run too hot for too long, etc). Second, bulbs do generally slowly dim, although they can actually shatter. In recognition of the latter I have read that some projectors have a lamp usage timer that will trigger a visual warning at some set point, and then actually shut down the projector at the limit set by the manufactuer. I don’t believe this is common, but it is done. That said, it would be a poor scheme that still allowed restart after multiple shut downs. But you never know … Third, consider some type of cooling related problem (e.g. a plugged or semi-plugged cooling filter). That said, this is usually a go/no go based on triggering the protection c
