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.

The only thing I can think of is raise the projector, that will help minimize the keystone effects. The best solution is to get it repaired.

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.

Re Keystone 68 projectors:
I join the growing throngs of folks who wish to view their family archives in 8 mm before submitting the reels to the digitals for conversion. Doesn't anyone have an answer for us? I continue to search, if I find, I'll post.
