Problem 1) The projector should put out a burst of 7000-15000 volts to start the lamp, and then immediately drop down to 60-100 vlts to keep the lamp lit. It sounds like the bulb blowing took out your ballast, or the ballast going out took the bulb (uncontrolled current = overheated bulb = boom)

Problem 2) Thats not a problem at all. HID lighting uses an arc to create light, just like welding creates light. Since it uses an arc, and not the heating of metal, there is no filament to test the resistance of. All the bulb is, is a special mixture of gasses and two very durable electrodes, with a gap in between.

SOURCE: Hi I have a view

Take a listen at the projector when it powers up... check if there is a whizzing sound and a buzz like sound. These are the color wheel and the ballast respectively. If one is missing take a look at that one first. If both are OK, then it is likely the lamp that is the issue. Like of the lamp is at 4000hrs if I am not mistaken.

You need to contact the company that sold you this lamp. The other way would be to contact Mitsubishi to get the replacement. As long as it is a factory original replacement part.

Red warning light


follow this steps and fix it. God bless you

  • 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.

  • 2
    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.

  • 4
    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.

Status light is blinking red, power button orange nec vt700


Hello
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.
