    The most likely problem is overheating. Do you hear the fan turning? If you can see inside the projector, do you see any accumulation of dust? Dust can collect and reduce airflow causing a problem even if the fan is turning.

    Just so you know, those of us who answer questions on this website are not employees of FixYa and we don't get paid. It's a strange hobby I know, but please keep this fact in mind as people here try to help you.

Lamp is burned out or makes a popping sound.
When the lamp reaches its end of life, it may burn out and may make a loud popping sound.

Status light is blinking red, power button orange nec vt700

Look at the number of blinks of the status light.
[1] If it blinks at one cycle (0.5seconds On and 2.5seconds OFF) : Lamp cover error or lamp housing error. Replace the lamp cover or lamp housing correctly.
[2] If it blinks 2 cycles (0.5 seconds ON and 0.5 seconds OFF): Temperature error. The projector is overheated. Move the projector to a cooler position.
[3] if it blinks at 4 cycles (0.5 seconds ON and 0.5 seconds OFF): Fan error. Fans sill not work correctly.
[4] If it bliks at 6 cycles (0.5 seconds ON and 0.5 seconds OFF): Lamp fails to light. Wait a full minute and then turn on again.
[5] If it blinks continous (Red): Lamp has reached the end of its life. Lamp replacement messege will be displayed. Replace Lamp with same type and number. After replacement reset lamp hour. OK.

Light of projector is not working

Try to turn off your projector and open it again after 10 minutes. The lamp may be malfunctioning due to overheat. This usually happens when your projector was not turned off properly. The fans inside the projector should slowly cool the lamp inside when turning it off properly causing the projector to be in a standby mode for a couple of minutes before you can completely unplug it.

What does it mean when that blinking green light turns to orange one in lp 350?

This would be "Standby"
When you press standby, the display and audio turn off and a blank screen is displayed for 15 minutes.
You can change the amount of time the projector stays in standby mode; see “Standby Time” on page 27 for details.
The LED lights orange while the projector is in standby.
• If you press standby again within 15 minutes, the projector returns to normal operations immediately. The LED changes from orange to green.
• If you press standby again after 15 minutes, there is about a 60 second delay before the lamp turns back on. The LED flashes green while the lamp is re-lighting.
• If you don’t press standby again, the lamp turns off after 15 minutes. The LED lights orange while the projector is in standby.

CP-S335 popping noise when powering on

Hi Eva

A Projector does'nt like being switched on and off all the time , if you are going to watch a couple of movies - rather leave the machine running all the time - this will also help you to get more hours out of your lamp - and that's a promise.

As far as the noise is concerned - it is most probably just the machine that was not cooled down properly at that stage.

NEC LT30 - Lamp dosen't turn on.

From the manual: To reset the lamp hold down the "HELP" button on the remote for 10 sec and the lamp indicator will turn off. Then start up the projector again.

It worked for me!

InFocus LP725 light goes out after 10 minutes

The Projector will turn off after so many hours of running the same bulb module. The counter will turn on a replace bulb LED. Installing the new bulb module should reset the counter and turn off the LED.

Check the projector’s lamp to ensure that it is securely connected
in the lamp module. Make sure by removing it and reinserting it.

Check the cables for problems.

When testing, power up in this order. Projector, Computer monitor, Computer.

A minor power surge may cause the lamp to shut off. Turn the
projector off, wait at least 30 seconds, then turn it back on.

I hope these suggestions help
