(Signal sent from the computer) If you project an image from a computer with an LCD screen while monitoring the image on the computer, the image may not be projected properly, depending on the computer model. In this case, turn off the computer display. For details on controlling the computer display, etc., refer to the computers manual and description on the software for the computer used. The TLP550/TLP551 projects an image by XGA signal (1024 x 768) in full screen. The image quality from a computer signal other than XGA may be inferior. It is recommended to set the external monitor connected to the computer to XGA mode (1024 x 768). The TLP250/TLP251 projects an image by SVGA signal (800 x 600) in full screen. The image quality of a computer signal except SVGA may deteriorate. It is recommended to set the external monitor connected to the computer to SVGA mode (800 x 600). The projector can be also applied to DDC2B (Display Data Channel 2B). If your computer is applied to the DDC, start up your computer after turning on the projector. If the order is reversed, the computer may not output any signal.

Press ON/STANDBY again.

(Orange)

C Notes

To protect the light source lamp, the LAMP indicator blinks as long as a minimum of cooling is necessary. The power cannot be turned back on during this time. Unplugging the power cord at this time will shorten the lamps duration life. The cooling fan continues to run for a while to expel the heat remaining inside. If you are in a hurry, however, you may unplug the power cord at this time. The standby mode is set.
The projector consumes about 15W of power in the standby mode. We recommend you unplug the power cord when not using the projector for long periods of time. Be sure that the LAMP indicator has turned off before unplugging the power cord. Cutting the power by unplugging the power cord while the projector is operating or the light source lamp is being cooled will shorten the lamps duration life. Should a fault or some other irregularity arise with this unit, unplug the power cord. When reinserting the power plug before the lamp has cooled, please wait until the lamp has cooled sufficiently before use. When the lamp is at a high temperature, it may not light and its life duration will be shortened.
Adjusting the picture automatically
You can adjust the optimum horizontal position, vertical position, sampling phase and sampling frequency for projecting analog RGB signals at the touch of a button.
Input full screen video signals from the input source (computer) and project the image.
Adjustments may not be performed properly for images that are not displayed on the entire screen or for extremely dark images.

Press AUTO SET.

The horizontal position, vertical position, sampling phase and sampling frequency are adjusted automatically. The icon appears during signal processing.
Automatic adjustment may not be performed properly for signals other than those computers signals with which the projector is compatible. The horizontal position, vertical position, sampling phase and sampling frequency can also be adjusted from the menu screen 46.

* Sampling frequency Analog RGB signals input from the computer are converted into digital signals inside the projector. The sampling frequency is the number of times per second the analog signals are converted into digital signals. In order to capture (sample) each individual dot of the computers signals, the sampling frequency must be adjusted to match the computers dot clock frequency. If this adjustment is off, details of the image details may be blurred, a striped pattern may appear if images with many vertical lines are displayed, or the images width may change. For computer signals with which are projector-compatible, the sampling frequency is adjusted automatically even when the AUTO SET button is not pressed. * Sampling phase The sampling phase is the timing at which the computers analog RGB signals are sampled. If the sampling phase is off, the individual dots cannot be sampled at the proper timing, resulting in blurred or flickering images.
Correcting the keystone distortion

Before correction

A picture may be expanded on the upper side if projected upward from the projector lifted up by the foot adjuster. The projector can correct this keystone distortion. After correction

Press KEYSTONE.

The keystone adjustment menu appears. (This menu is the same as the sub-menu which is displayed when Correct the keystone distortion of the screen is selected from GUIDE MENU. 44 )

EXIT EXIT

Adjust the distortion with the selection buttons ( / ).
: The upper part of the screen shrinks. : The upper part of the screen expands.
To finish the adjustment, press EXIT repeatedly until the menu disappears.
Turn the lens shift dial clockwise fully before using the foot adjuster. 20 Due to digital correction processing, some of the information may dropped or the picture quality may be degraded depending on the keystone correction setting or the contents of the signal source.
Cutting off the picture and sound temporarily
The image and sound of this projector can be turned off if you wish to temporarily project the image from another projector or an OHP, etc., onto the screen.

You can adjust the Sharpness of the camera image on the menu screen. 45 If the image flickers due to a fluorescent light in the room, either turn off the fluorescent light or set the Shutter on the menu screen. 45 Note that the image may still flicker due to the lighting, the document status, the image adjustment, etc., even if the Shutter setting is changed.
When finished, turn off the light and close it, and put back the arm.
Follow the steps of Preparation of the document imaging camera in reverse.
The light turns off automatically when the arm is inclined. When the arm is not raised up, the camera source cannot be projected. In the camera input selected, the sound is not emitted.

Locking the white balance
This projector s camera is always being adjusted automatically for projected color balance; however, the balance can shift away from optimum due to the color scheme of the document. Should this occur, the white balance can be set to a fixed condition by using the following procedure.
Project a white paper and enlarge it to fill the screen.

W.BALANCE

Press W.BALANCE to turn the LOCK indicator on.
The white balance is locked. To release the white balance, press W.BALANCE again to turn the LOCK indicator off.
If you raise up the arm while the camera input is being selected, the color of the picture may vary for an instant due to the automatic white balance adjustment. This is not a malfunction. If you put the arm back and raise it again while the white balance is locked (the LOCK indicator is lit), the projector will release the white balance. Should this be the case, or if you would like to adjust it to a desired tint, adjust R-level, G-level or B-level on the FULL MENU [Color] screen.
Correcting illuminated defects
For the CCD image sensor used in the camera unit, in rare cases some of the pixels may be disturbed due to the influence of cosmic rays, etc. This disturbance may cause white spots to appear on the picture. If white spots appear on the document camera image, use the procedure described below to correct the problem.
With the document camera operating, fully cover the camera lens with a piece of black paper or cloth.

Camera lens

Press both sides Camera control panel
Press ARM LIGHT on the camera control panel and EXIT on the projectors control panel simultaneously.
You can not use the remote control buttons.
Do not press ARM LIGHT and EXIT buttons simultaneously if the camera lens is not covered. Doing so will not only erase the white spot correction data already set but also result in parts ot the image that are properly displayed being corrected. Also be careful if the camera input mode is not selected.
