<!-- from fixya rte -->Why won't my projector stay lite? - Office Equipment & Supplies

Hi there.
Check for wiring errors, fix and tighten all wiring connections. Make sure that the gas pressure is correct.
Check the hi limit and gas valve, one of those component may be bad.
Regards.

Thermostat flame sensor. Do you see a little rod next to the pilot? That is what tells the main gas valve that the pilot is lit and it is safe to give gas. Easy swap, and you can usually just pick up a generic one.

The oriface may be partialy plugged or the thermo-couple is bad.

the projector lamp is run out

The ambient temperature in the room is to high.
Try lowering the room temperature. If that doesn't work
get a small fan and place it near the projector to provide
extra cooling. The projector is running border line on
high temperature and just needs a little extra cooling.

The lamp reset...should only be used when you replace
the lamp..with a new one...The reset will start the clock
running on the number of hours the new bulb has used..

These projectors were designed & made by Telex for Kodak.
If the screen stays black when you push a slide down into the "gate" (in either viewer or projector mode), then the trip mechanism that opens the shutters when a slide is detected has a problem. It could be an adjustment, a broken or out of position spring or hardened lubrication.
There is no good way to proceed unless you are trained in the service of these projectors. Contact a factory-trained repair dealer. Happy New Year!

The manual says it might be because the power went out when it was on. Just a note here, as projectors age they become more sensitive to power outages. When not in use turn off completely if you can. They have an on/off button.

Otherwise not sure but think you may need to replace the fan. Try cleaning it first but gently.

Try cleaning the filters.  

no with the red lite on it mean that you need to change your filter its a safety feature so you dont burn out your motor and also so you dont blow unpurified air through out your home
