Question about NEC LT 240K Multimedia Projector

1 Answer

NEC LT240 has Power, Status & Lamp indicators lit & wont turn on!

Last week my projector shut itself off and went into a mode where it had the Power, Status & Lamp indicators lit and it wouldn't respond to being cut on from the remote or the actual unit. All that happens when you turn the power switch in the back of the unit to the on position is the 3 indicators light up. No fan activity, no lamp activity, no anything! My bulb warning had just recently appeared a few weeks prior, so I thought the bulb must have gone out and the unit went into some sort of standby mode because it needed replacing. I ordered the new bulb and installed it but the same problem remains. I have searched the manual and the net for a solution but can't find the 3 steady lights problem in any troubleshooting menu or forum. I am desperate and dying without my projector! If anyone has a suggestion please let me know! Thank you so much!

If your bulb finally reaches it's end before you have the chance to replace it you unit will shut itself down and go into a permanent standby mode. Changing the bulb alone will not remedy the issue. The solution is quite simple but not posted in the manual or anywhere else that I could find for that matter! All that is required is to hold down the HELP button on your remote for 10 seconds while aiming at the infrared sensor on the unit. This will reset the units bulb timer and remove it from the standby mode.

SOURCE: I have a NEC VT470

steady orange means projector in standby mode
red light 6 times is a lamp error.
either the lamp is old and wont start up or the ballast power pcb is not working.
can you hear the sparking of the high voltage trying to strike the lamp.
if you can then the lamp may be dodgy.
can you borrow one to test it out

SOURCE: NEC VT595 Projector - Status light blinks red constantly

Hi Craig,

If you get no lamp light at all coming from the main projection lens then odds are the lamp ballast or power supply has failed. These can usually be repaired & is a common fault among the VT series projectors. If one of the fans are stuck the unit normally still lights up for a few seconds up to 20 seconds or more until the extra heat trips the safety shutoff & shuts down the projector.

SOURCE: Steady red status light on NEC VT45 projector.

the power supply on that model seem to go bad after a while. the caps aren't properly reted it's power needs. they dry up. if you are good at soldering, replace c1 on the board (big cap) with a cap that has a slightly higher voltage rating. or replace the whole power supply. you might not be able to get one from nec, but you can try www.projectordoctor.com

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.

It sounds like the lamp is going.
Do you know how many hours of use are reported on the lamp?

Many times these projectors have circuitry to shutdown when they suspect the lamp is near the end of life. Lamp hours vary and usually will go up to and even beyond expectancy, but there is occasions you can receive a bad lamp and have it blow in a matter of hours...not common but it does occur.

I hope this helps,

The early lamp failures are due to poor air flow or longer hours of use.
So take care to clean the filters, see that the lamp brigtness is not put too high and reduce the hours of continuous use.

It is an indication that the projector is in sleep mode. Press power button and check for any changes on the led indicators. If the power turns red, it means unit is hot. check if the fan is working and if the air filter is clean or needs cleaning. If the lamp turns red it means the lamp is busted, You will experience this since lamp is clearly blown. But if both lights are red, it means that the unit is busted and will require service.

I have a NEC mt1055 and the unit just had new bulb put in here and it has the power and standby light come on and the fan doesn't turn on here and the standby light is yellow and status is red


The NEC’s work on a reducing time basis, they count the hours that they have been operational and refer to this as the life of the bulb – 1600 hours. When the 1600 hours has been reached the projector shuts itself down into standby mode never to be restarted even after changing the bulb / filters. This is because the unit needs to be reset, which needs to be done as follows (not included in any of the bulb replacement instructions):-
  • Plug Projector in so it is in standby mode – Orange light lit, Red status light lit (not flashing)
  • Using the remote control, hold down the power off button for 30-45 seconds
  • This will reset the status button, removing the red light
  • Power up the projector and select Menu
  • Select Projector Options
  • Select Set-up – a number of tabs will appear called pages
  • Arrow across the pages (MT850 is Page 5) until an option called “RESET LAMP HOURS” is shown
  • Move onto this option and press enter on the projector itself, confirm that you want to reset the counter
  • Projector is now back to life

This works for all NEC projectors, the page number may be different though where the “RESET LAMP HOURS” option resides.

Projector turns off after about 30 minutes. What's wrong?


your projector status means the protection circuit is working or the lamp is in an abnormal condition.
