First thing you need to know is that the bulb gets very hot while its on. If you handle the bulb with your hands, you may place oil (yes body oil) onto the service of the bulb. If you can avoid hands on placement of the bulb. The bulb will position into the socket in only one directioin. Look at the center of the bulb, it should face towards the mirror that reflects the light to the film gate. Since the bulb is held in place by pressure, GENTLY push the bulb into the sockett.
BEFORE you replace the bulb, you should look at the mirror on this projector. If it seem dirty with dust, you should take a q-tip swab, dip it in alchahol, and clean the mirror. If there is any dust inside the projector housing, use a vacume to suck it off the services. You can pull the lens out of the socket to use a cotton swab to clean both sides. To get the lens out, pull gently on the focus know along side of it, and the lens could be pulled out.

How do I correct a trapezoidal display?


This is called keystoning and there should be a setting on your projector that will compensate for this problem. Usually it will be called keystone adjustment or something like this.

I have problem with christie projector roadster x9


If your's is the "s" model there is no keystone adjustment provided. Otherwise the keystone adjustment is found under MENU then 1, Size and Position and under MENU 2, Image Settings. Also, refer to this excerpt from the manual:
NOTE: This function is not available in "S" models.
Adjust the keystone control if images appears non-rectangular or keystoned in shape-that is, smaller at either the top or bottom edge. The effect of keystone adjustment is similar to
physically tilting the projector forward or backward in relation to the screen, and it affects all sources.
NOTES: 1) Keystone is enabled for a source only if Size is 1000 and Size x Vertical Stretch is 1,000,000.
2) Keystone adjustment is not available in "S"
models. 3) Avoid using Keystone with Blanking.

Keystone not working


Manual: http://www.mitsubishi-presentations.com/wp-content/files_mf/mitsubishi_manual_xd250ust.pdf

Installation>Wall Screen>Keystone

The automatic keystone adjustment may not be carried out correctly

because of the ambient temperature and the installation

conditions of the projector and the screen. In such cases, correct

the keystone manually.

• When the projector is projecting images where acceleration is

present, such as in a vehicle and aircraft, the automatic keystone

adjustment may not function correctly. In such a case, set AUTO

KEYSTONE in the INSTALLATION menu to OFF and correct the

keystone manually.

• You can correct the vertical keystones. However, their adjustment
ranges are limited in such correction.

When the keystone adjustment is carried out, the adjustment

value is indicated. Note that this value doesn't mean a projection

angle.

• The allowable range of the adjustment value in the keystone

adjustment varies depending on the installation conditions.

• When the keystone adjustment takes effect, the resolution

decreases. In addition, stripes may appear or straight lines may

bend in images with complicated patterns. They are not due to

product malfunctions.

• Noise may appear on the screen during the keystone adjustment

because of the type of the video signal being projected and the

setting values of the keystone adjustment. In such cases, set the

keystone adjustment values in the range where the image is displayed

without noise.

• When the keystone adjustment is carried out, the image may not
be displayed correctly because of the type of input signal.

Projectors


Look for a "keystone" option in the menus, or possibly even directly on the remote itself. You should be able to adjust this one way or the other to digitally square up the image at the cost of some resolution and smoothness. Mind that it might instead have auto-reset itself because you moved the projector around also, some of them have an auto sensing function but it never works very well, might as well turn it off and tweak it manually. Also be sure to zero the keystone and physically true it up as best you can using the extendible legs before using the digital keystone to finish the job if necessary.

And thanks for being the first question I've seen out of a run of about ten which was both presented in full and understandable English sentences, and wasn't just something that could instead have been entered directly into google to get an easy answer... :-)

How do you change the lamp in a mod # 980Z keystone projector


There is a black and silver knob under the keystone label( right above the automatic label ) on the side of your projector. turn this knob counterclockwise to loosen the covering over the housing unit for the lamb. once the knob is loosened lift the housing unit off of the side of the projector. You wlll see the enclosure where the lamp fits into beneath it.
Make sure the power is off for your projector while doing so. Screw the lamb into the enclosure , then replace the covering and screw the black knob in clockwise until it tightens.
