Still need help after troubleshooting?

If the projector appears to need repair, there are two options:

  • Call the manufacturer (Epson) at 562-276-4394 to find out if your projector is under warranty and also for additional troubleshooting assistance. If it is under warranty and needs repair, Epson will take care of that. They will send you information for returning the Unit to Epson for Exchange. Do not use a personal or district credit card as a hold in order to have the unit shipped to you.  Epson will send information to return the item through UPS (shipping is paid by Epson). Prior to sending the Unit, Complete an Equipment Transfer Form listing that the equipment was sent to the vendor for repair work and send the form to MDC.  It is also necessary to complete a Return Material to Vendor Form in case we will be receiving a credit for the item. To obtain this form, contact MDC at 472-0940 or Educational Technology at 472-0004. This form goes to MDC, Purchasing and Accounts Payable so everyone is in the loop. Returned items should be shipped through the MDC mail-room.  Questions regarding this process can be addressed by purchasing at 472-0143.
  • If the projector is out of warranty, your school can pay Epson to repair it.
  • EdTV will no longer send projectors and document cameras for repair. Replacement lamps are now available from the MDC catalog (listed as "Lamp, Epson").


Basic tips for any issue:

Turn off the projector and unplug it and disconnect all cables. Plug it back in and reconnect cables.

Use on-screen help by pressing the ? Help button on the top of the projector.

Or try some of the solutions for specific issues below:



Clear area around the projector to ensure that nothing is blocking the vents.

Clean the filter and vent. Turn off the filter first and let it cool. Remove the air filter to gently clean both sides: 83+ or 93+.

The projector will get hot. This is normal.
If you are not seeing a warning message and your projector is not shutting down on its own, then it is probably not overheating.
