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.

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.

Replace bulb in housing for Infocus IN24.. i want instructions how to remove old bulb from housing.


1 Turn off the projector and unplug the power cord. 2 Wait 60 minutes to allow the projector to cool thoroughly. 3 Turn the projector upside down on a soft cloth so that the lamp door is facing you. 4 Slide the lamp door off. WARNING: Be extremely careful when removing the lamp housing. In the unlikely event that the bulb ruptures, small glass fragments may be generated. The lamp housing is designed to contain these fragments, but use caution when removing the lamp housing. Before replacing the lamp, clean the lamp compartment and dispose of cleaning materials. Wash hands after lamp replacement. Hg ? Lamp contains mercury. Manage in accordance with local disposal laws. 5 Detach the lamp connector from the projector by depressing the locking tab on the connector and lightly pulling it free. 6 Loosen the captive screw that attaches the lamp housing to the projector.Carefully remove the lamp housing. Dispose of the lamp in an environmentally proper manner. 7 Install the new lamp housing and tighten the screw. 8 Re-attach the lamp connector to the projector. The locking tab should engage when the connector is fully plugged in. 9 Replace the lamp door by sliding it into place. Be sure the lamp connector wires are not in the way. 10 Plug in the power cord and press the Power button to turn the projector back on. 11To reset the lamp hour timer, navigate to the Settings>Service menu and select Reset Lamp Hours.

Replacement lamp


The lamp you received is correct. I own a lamp replacement company. It may of been pakaged incorrectly or maybe you received just the bulb and not the housing or vice versa (housing included). First, unless housing is damaged NEVER buy a new one...just the bulb will do. Housings are the biggest markup on replacement lamps. They are manufactired at a low cost and usually retailers drive up the lamp price because they include an uneeded housing. The bulb itself (XL-2100U) should be a round bulb. Check out my listing and compare this to what you received:
