There are several things that can cause this problem, but the first thing I would check is the filter. The projector requires airflow to keep it cool. If airflow is blocked, the projector will overheat and shut down automatically.
The first may be due to overheating. Most projectors have a "air filter" that can be removed and cleaned. If it gets clogged with dust over time, the projector can't breathe and shuts down.
The second cause may be your lamps life hour clock. Most projectors keep track of the amount of time that their bulbs have been active. Once a preset # of hours has passed the projector will limit functionality until a new bulb has been installed AND the lamp life clock reset. Most projectors do not automatically reset the lamp life clock after a new bulb is inserted.
There should be instructions on how to reset the lamp clock in your users manual, and info on cleaning the air filter. Unfortunately I went to the Sanyo website and was unsuccessful in locating a PDF of the user manual for you.
Reset the lamp timer.
1,Connect the power cord.
2,While simultaneously holding down "menu","enter" and "down" on the projector, press "standby/On" on the projector and keep all four buttons pressed down until the lamp indicator starts blinking green.
"LAMP 0000H" is displayed, indicating that the lamp timer is reset.
You will have to reset the lamp timer as follows :
Hold down the up arrow key on your projector for a couple of seconds - projector must be switched on.
You'll see a on screen message appear in one of the top corners on the image....then just follow the two basic steps as requested on screen.....your lamp timer will now be reset.
Then shut down the projector and restart for changes to take effect.
