  • Secure the lamp cover and the air filter cover of the projector body if the projector does not power on. Ensure that the power cable is firmly connected to the projector and an active power plug. If the projector was turned off and then on quickly--let it sit for 90 seconds before trying to turn it on.

    Replace the projection lamp if the projector will not power on or if the lamp indicator is flashing. Turn off the projector and let it sit for at least 30 minutes. Locate the lamp cover and remove or loosen the lamp cover with a screwdriver. Carefully remove the projection lamp from the projector housing using the handle, if available.

  • 3
    Place the new projection lamp into the projector housing and secure it to the projector. Replace the lamp cover and reset the lamp timer. Power on the projector to ensure the new lamp is working correctly.

    Remove the projector from the enclosed area to allow air circulation if it constantly overheats. Place the projector into an open area and make sure there is no blockage for the ventilation holes. Unplug the projector for at least 45 minutes to allow it to soft reset.

  • 5
    Clean the air filter to allow the projector better air circulation. Turn off the projector and unplug it from the outlet. Remove the air filter cover and use a vacuum to remove dust from the area. If the filter is unable to be cleaned correctly or is damaged, then replace it. Pull the air filter from the projector and place the new one in the now empty slot. Close and secure the air filter cover.

This projector was given to me by a friend. The control buttons on the top of the projector do not seem to work. The projector seems to work fine otherwise. Any idea what the problem could be?

The projector was in security mode B which lock all of the projectors controls. I found the solution to this problem in an online manual for the projector. The solution is this button sequence: power-- enter-- power--enter-- power--- enter-- menu. This sequence unlocks the projector controls by resetting the security password.

Kodak 410 Projector/Viewer - no lite through projector or viewer

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!

If you're getting a black and white image with or without source, it's probably the color wheel. Do you hear anything loose inside the projector? if you do it's the glass fragments of the broken color wheel.
