This is a general scenario seen in the projector as the projectors need to heat up to a certain temperature before they project any image on the screen. The internal temperature which the projector needs to attain is much higher than room temperature which causes the projector to heat up.

In general, every projector has a ventilation system so as to reduce its internal temperature and dissipate as much heat as possible into the environment so as to maintain a stable internal temperature of the projector preventing it from overheating.

But it may not always be the case where the ventilation system is working properly causing your projector to be overheated. Here are some ways on how we can protect a projector from overheating and how we can solve the problem of fixing an overheating projector problem.
