Projector i have a sharp notevision xr-1s projector and it heats up really fast and then shuts off because the temperature gets way to high, what is my problem or how can i fix it?

Just recently my xr-1s has been shutting off with only about 5 minutes
of operation. The temp symbal comes on once it shuts down the only way
to get it to power up again is to disconnect and reconnect power cord.
then the same happens. I cleaned out any possible debris from the
inside and it still does it. its is rarely used as it is in our family
room in the basement (which is climate controlled. I am at odds.
