My projector is displaying 'The projector's operation will be locked'. What should I do? Some Epson projector models include a password protection feature as a precaution against theft. In the case of special, educational use only 'e' editions like the EB-X6e, this security measure is enabled by default.
When password protection is enabled, entering the wrong password three times will cause the projector to be locked. A power cut or other power outage can also trigger the projector's security. In either case, the projector will then display:
  • "The projector's operation will be locked"
  • "Request Code xxxxx" (a 5-digit number)
This article explains what to do if you receive this message, and answers some related questions.
The projector will display the error message for approximately five minutes, then switch to standby mode. When this happens, follow the steps below to reset the projector.
Warning: Please follow these instructions exactly, and only carry them out when absolutely necessary. Entering a password incorrectly 30 times in succession may cause your projector to become "hard locked". If this happens, your projector can only be unlocked by a specialist engineer.

How to reset the projector

  1. Power off the projector using the power button on either the projector or the remote control.
  2. Remove the power cable from the back of the projector. Caution: You must physically remove the power cable from the projector. If the projector is ceiling-mounted and connected to the mains by a long extension cable, ensure that the cable is fully unplugged from the wall or ceiling power socket. The projector must be completely disconnected from the mains power supply or it may not reset correctly.
  3. Leave the projector disconnected from the mains for 15 minutes.
  4. Reconnect the power cable and power on the projector.
  5. The projector should display your normal password prompt screen. Enter your password and the projector should resume normal operation.Otherwise, if the projector still displays the same message, repeat the steps above and ensure that the projector is fully disconnected from the mains for 15 minutes. If there is still no change then contact Epson for further advice. Please note that you will need to provide the following:
    • The projector's serial number (located on the rear of the unit)
    • The 5-digit Request Code displayed by the projector
    • A copy of your proof of purchase for the projector

My Epson TW 700 suddenly went black,and the fan startet to go very fast.I could also see the red light ( temp. Indicator? ) coming on.Tried to cut the power, cleaned the filter and start it again, but...

Don't cut power to a projector when you power down. The fan has to run after the projector is powered down so that the lamp can cool evenly. If you unplug or if there is a power failure the lamp will develop cracks around the edges of the reflector and will fail quickly. If the fan is not moving air through the projector, it will overheat and shut down.

Epson Projector, Model: EMP-X5, Epson projector shuts down after 30 minutes work

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.

Why does my epson emp 700 projector cut off after ten mins even when the fans are working

These models of projectors form Epson have a standby which the projector enters when it no longer senses video input. The fans will continue to run because they are cooling down the lamp which remains hot for a few minutes after it turns off.
This could be a problem with your computer, or dvd player, or whatever device you are using for your movies. Check to make sure these are working properly. Check to make sure that your dvd player or computer is still outputing video to the projector.
If this does not fix your problem, then the problem could lie with the projector itself. The projector fans may not be properly cooling the lamp, in which case the projector will turn off the lamp to ensure the projector is not damaged. To fix this, you could check if the fan outlets on the projector have become clogged with dust. If they have, definitely clean them out with compressed air.
Hope this helps.

The projector does not seem very bright it has done 1200 hours is it the bulb or something else

Most likely the bulb, although it could be the power supply or lamp ballast. Most regular bulbs are rated for between 1500 - 2000 hours. They tend get dimmer as they age, but some will stay bright until they blow. Using low intensity/Eco mode, being sure air flow/ventilation is clear and open, and allowing the machine to go through the cool down process before shutting it off will all extend the bulb life. If you put the machine in the high output mode and the intensity improves, the it's probably the bulb.

The cooling fan stop working on my Epson EMP 700 Multimedia Projector, can I get a replacement part and replace it myself?

The temperature indicator is red.
The projector is overheating, which turns the lamp off
automatically. Let the projector cool for a few minutes,
then turn it back on. Make sure nothing is blocking the
ventilation vents.
If the projector continues to overheat after you clean the air
filter, the problem may be caused by damage to the cooling
fan or internal circuits. Contact a qualified service person.
¨ Warning: Do not attempt to service this product yourself except
as specifically explained in this User's Guide.

Epson Emp-x5e temperature light flashing

The temp light flashes due to internal temperatures being too high...this is most often caused by a clogged dust filter--clean the filter often--I clean mine once a week! Excessive heat causes all internal components to age prematurely--lamp, circuits, and lcd panels, Just be aware though...your projector is now considered "end of life" and a newer model has replaced it.


There is an adjustment in the Video section for adjusting it to look square.
