Keystone colortrac 2000

I have a RCA Colortrac 2000 that has been an excellent tv. It began "keystoning" a few months ago. Every once in a while, a full picture is displayed. Is there an adjustment I can make within the cabinet of the tv?

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.

I purchased Keystone Electric Pressure Cooker Model 99731 from QVC several months ago. Regrettably, there was no instruction manual with it. I am very anxious to make good use of it and need the manual. ...


Keystone produces pressure cookers for many brand names. Here are the brands produced exclusively for QVC - see if the manual for your cooker here:

Cook's Essentials:

Deni:
http://www.hippressurecooking.com/category/manuals/deni/

Many of these cookers have similar buttons and functions, so if you don't find an exact match use the manual that is closest to your pressure cooker.
