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.

How do I angle the projector at the side of a screen & get the screen view of it straight?


In projector menu you will find a setting called 'keystone correction'. Use horizontal and vertical keystone correction to correct the projected image.

There is a setting called keystone correction. Use this to correct the projection.
Go through the menu and you will find how to use keystone correction.
If you can't figure it out, keep the projector further away from the wall, on a higher stand. Reduce horizontal angle.

hello, since i don't know what type of projector you have, going by some of epsons projectors, you may want to try the keystone correction, the symbol for keystone is a trapezoid, also some of the old ones had a adjuster knob on outside of machine to correct lens, most new ones should be electronicly thru wand or thru key pad on machine

Tv not showing a picture


Hello e26pitts,

If the line is horizontal then it could be a problem in your vertical deflection section, if the line is vertical then the problem is in your horizontal deflection section. Now for a little more detail.

If Horizontal line is present the vertical section of the yoke transformer is nit responding to current flowing through it due to being open, or the vertical coupling capacitor is open, or even the vertical drive transistor might be defective.

If Vertical line is present the horizontal section of the yoke transformer might be bad. Now this gets kind is easy in a way, because the yoke would be the sole cause of your problem here (maybe there is some circuitry doing some horizontal coupling check that to) because the horizontal section controls other functions that would also respond if this were a horizontal drive issue. In any event these problems should be checked by a qualified TV technician, I would suggest that you take the TV to a repair shop to have it worked on.

I hope this helps
Thank you,
Shuttle83
