CalibrationUse the Calibration menu to perform advanced picture quality adjustments. This menu 
should be used by ISF-certified technicians only. 
To recall the ISF Night or ISF Day settings, select “ISF Night” or “ISF Day” from the ISF Presets 
menu (see 
page 58) or use the corresponding buttons on the remote control. 
ISF Night - Display Color: Use the Display Color settings to adjust the color balance at the 
projector output. These settings are saved independently for each input.
•Gain: Use the Gain controls to correct color imbalances in the bright areas of the image. A 
good way to do this is to use a test pattern consisting mostly of solid white areas, such as 
an 80 IRE “window” pattern. If the white areas contain traces of red (Pr), green (Y) or blue 
(Pr), decrease the Gain for that color.
• Offset: Use the Offset controls in the White Balance sub-menu to correct color imbalances 
in the dark areas of the image. A good way to do this is to use a test pattern consisting 
mostly of dark gray areas, such as a 30 IRE “window” pattern. If the gray areas contain 
traces of red (Pr), green (Y) or blue (Pr), decrease the Offset for that color.
•Gamma: “Gamma” is a global setting that determines how gray shades are displayed 
between minimum input (black) and maximum input (white) for all signals. A good 
gamma setting helps to optimize blacks and whites while ensuring smooth transitions for 
the “in-between” values utilized in other grays. Unlike “Brightness” and “Contrast” 
controls, the overall tone of your images can be lightened or darkened without changing 
the extremes and all images will be more vibrant while still showing good detail in dark 
areas. 
In all but the most unusual situations, the appropriate “Color Temp” selection (see below) 
will produce accurate colors and a satisfying contrast level. However, it is sometimes 
necessary to adjust the red, blue and green gamma curves individually. To do this, select 
Gamma from the Display Color sub-menu and use the left- and right-arrow buttons to 
manipulate the on-screen slidebars. 
• Color Temp: Select Color Temp from the Display Color menu to adjust the color 
temperature. The default setting is appropriate for most situations. Higher settings 
produce a “bluer” picture.
ISF Night - Input Image: The Input Image controls are similar to those in the Picture menu, 
but are accessible only by entering the Calibration menu passcode. This makes it possible to 
restore the picture quality settings to what they were when the projector was installed, 
simply by recalling the “ISF Night” preset.

ISF Night - Input Color: The Input Color controls are similar to those in the Display Color 
menu (see above), but adjust the color balance of the incoming signal. These settings are 
also saved independently for each input. 
• Gain/Offset: Refer to ISF Night - Display Color, above. 
• Chroma Delay: use the Chroma Delay control to correct a mis-aligned image from a 
Composite, S-Video or Component video source. Chroma delay in an image causes color 
shifts to occur to the left of the vertical edge transitions, producing artificial shadows or a 
“halo” effect. If necessary, adjust this setting to eliminate them. 
• Noise Filter: To apply noise filtering to the input signal, select Noise Filter from the Input 
Color menu. The Noise Filter is useful for clearing up noisy images from 480i video 
sources. 
Use the left- or right-arrow buttons to select the desired amount of noise reduction, 
keeping in mind that higher settings (which reduce high frequencies) may also “soften” 
the image.
ISF Day - Display Color: Refer to ISF Night - Display Color. 
ISF Day - Input Image: Refer to ISF Night - Input Image. 
ISF Day - Input Color: Refer to ISF Night - Input Color. 
Save ISF Settings: Whenever you make a change to the ISF settings, you should always save 
it. Select Save ISF Settings from the ISF Calibration menu to do this. In the event you ever 
have to perform a 
System Reset, you can restore the saved ISF settings by selecting Restore 
Saved Settings in the Service menu. (System Reset and Restore Saved Settings are described 
on page 62.)
Output Shift: The controls in the Output Shift menu are similar to those in the Input Position 
menu, except that they change the characteristics of the output signal. These settings are 
saved independently for each aspect ratio. 
Splash Timer: Select Splash Timer from the Calibration menu to set the amount of time the 
Vidikron/ISF logo “splash” screen appears when you turn on the projector. The range is from 
5 to 60 seconds, in one-second increments. 
OSD Position: To adjust the position of the OSD, select OSD Position from the Calibration 
menu and press ENTER (or SELECT). 
Press  or  to select “Hor.” or “Ver.” Then, press  or  change the position.

ServiceUse the Service menu to access advanced projector configuration settings. This menu 
should be used by ISF-certified technicians only.
Test Video: Select Test Video from the Service Menu to access the internal test patterns on 
the Vision 120. Four patterns are available: 
Horizontal Ramp, Vertical Ramp, Color Bars 1 
(solid bars) and Color Bars 2 (SMPTE “checkerboard” pattern). 
Press MENU to exit test pattern mode. 
Display Device: The options in the Display Device menu allow you to change the picture 
orientation and perform lens adjustments.
• Installation: Select Installation from the Display Device menu to change the picture 
orientation to suit the method of installation (Floor Front, Floor Rear, Ceiling Front or 
Ceiling Rear). 
•Lens: Select Lens from the Display Device menu to access the motorized lens controls. 
Refer to 
Primary Lens Adjustments on page 41. 
•Lamp Info: Select Lamp Info from the Display Device menu to obtain information about 
the currently-installed lamp: its serial number, number of “strikes” (attempts to ignite) and 
number of hours in use. 
•Diagnostic: Select Diagnostic from the Display Device menu, then select Red, Green, Blue, 
Yellow, Cyan or Magenta to display only that color (simulating a filter of that color). This 
can be useful for calibration or measurement purposes. 
To restore the normal picture (all colors), select White. 
HD Format: Select HD Format from the Service menu to choose the default color space for 
the source signals on the HD1, HD2 and HD3 inputs. Select COMP (component) or RGB. The 
VHD Controller assumes this color space when you “direct-select” an HD input using the 
left-arrow and right-arrow (
 or ) buttons on the projector rear panel or VHD Controller 
front panel, or the HD1, HD2 or HD3 buttons on the remote control unit.
You can override this setting by using the OSD to select an HD input (refer to Input Source on 
page 51). For example, if you select COMP for HD2 here and the input signal changes to RGB, 
select “RGB BNC” from the Input Source menu to enable the Vision 120 to properly display 
that signal.

Triggers: Select Triggers from the Service menu to configure the 12-volt trigger outputs. You 
can assign one or more trigger outputs to each aspect ratio. Those triggers are then activated 
by selecting that aspect ratio. 
If your projector is equipped with the Vidikron CineWide with AutoScope system, assign at 
least one trigger output (the same one to which the lens motor is connected) to the Cinema 
and IntelliWide 2.35 aspect ratios.
Miscellaneous: Select Miscellaneous from the Service menu to set the following options: 
•Language: Select Language from the Miscellaneous menu and press the up- or 
down-arrows to select the OSD Language (English, Français, Deutsch, Español or Italiano). 
•OSD Timer: Select OSD Timer from the Miscellaneous menu to set the OSD Timer, which 
controls how long the menus remain on-screen after selecting them. Select from 5 to 60 
seconds, in one-second increments. Or, set the timer to 0 (disabled) if you want the menus 
to remain on-screen indefinitely. 
•Film Mode: Use Film Mode to smooth out moving images from interlaced, 
standard-definition (SD) sources. In most cases, the Vision 120 detects the proper 
“pull-down” rate and vertical frequency. However, if your source is jittery and/or tearing 
you may wish to enable Film Mode (ON) to ensure stable processing for that source. 
•CUE (Chroma Upsampling Error) Correction: Some DVD players use MPEG decoders 
that do not correctly “upsample” the 4:2:0 format chroma information on the DVD to the 
4:2:2 or 4:4:4 format required by the video encoder of the display device.
This so-called “chroma bug” sometimes causes streaky or spiky horizontal lines running 
through the chroma channel. It is most noticeable in static, interlaced scenes and on 
diagonal edges (especially red ones). Set 
CUE to On to correct this issue. 
•Motion Threshold: The Motion Threshold determines the difference between a pixel and 
its corresponding value in the previous field or frame that must be exceeded for the pixel 
to be considered moving. 
Increase the Motion Threshold if the image appears excessively noisy or if moving objects 
appear blurred. Decrease it to reduce or eliminate artifacts caused by deinterlacing errors. 
System Reset: To reset ALL projector and controller settings (including image settings) back 
to their factory defaults, choose 
System Reset from the Service menu. 
A confirmation message appears, reminding you to save your settings before you perform 
the reset, so that you can restore them afterwards. If you have done this, select Confirm to 
continue with the reset. Otherwise, click Back to cancel. 
 
Restore Saved Settings: Following a System Reset, select Restore Saved Settings, then 
select Yes to apply all previously-saved settings to the projector and VHD Controller.
This action is not undoable. Proceed with caution! Before you perform a 
System Reset, save your “Custom” ISF presets (
page 58) and ISF Day/Night 
presets (page 60).

5.1 
Lamp Replacement
The lamp should be replaced when it reaches the end of its life (typically 2000 hours), or 
sooner if a noticeable degradation in brightness occurs. When you replace a lamp, you 
should replace the filters as well. 
For lamp or filter replacement, please contact your nearest Vidikron authorized service 
center or Vidikron dealer. Do not attempt to replace the lamp yourself!
1. Turn off the projector and unplug the power cord. Allow the projector to cool down for 
approximately 45 minutes prior to removing the lamp assembly for replacement.
2. Loosen and remove the rear Lamp Cover screw.   
 
 
 
3. Slide the Lamp Cover in the direction of the arrow 
to remove it. 
 
 
4. Loosen the two, captive lamp assembly mounting 
screws using a coin or a large, flat-blade 
screwdriver. 
  
 
5. Grasp the lamp assembly handle and pull gently, 
removing the lamp module from the projector 
housing.
 
 
 
5Maintenance and Troubleshooting
The Vision 120 lamp is under high pressure. Handle it with great care at 
all times. Lamps may explode if dropped or mishandled. 
Never attempt to disassemble the lamp casing or dispose of the lamp 
casing in any manner other than by returning it to your Vidikron dealer.
If the lamp breaks, leave the area immediately and stay away for at least 
30 minutes. Ventilate the room to allow the mercury vapor to disperse.
If you inhale the mercury vapor, see a physician immediately.

Troubleshooting Tips
Table 5-1 provides some general guidelines for troubleshooting problems you may 
encounter with the Vision 120. If the suggested solutions fail to resolve the problem or if you 
encounter an issue not described here, please contact Vidikron Technical Support. 
Table 5-1. Troubleshooting Chart 
SymptomPossible Cause(s)Solution
The projector does not turn on 
after initial installation. The 
power LED on the front of the 
VHD Controller lights red after 
you press the power button.  The VHD Controller is 
connected to the Vision 120 
incorrectly or not at all. 
 
 The Vision 120 is not 
plugged in or the AC outlet 
is not active. 
 Verify the DVI-DL cable 
connection from the VHD 
Controller to the Vision 120 
(
Figure 3-10).
 Ensure that the Vision 120 is 
plugged in and that the AC 
outlet is active. 
The projector and VHD 
Controller are both on, but 
there is no video image 
on-screen.  Incorrect source selection. 
 Source component is not 
turned on. 
 Select the correct source. 
 Turn on the source. 
A projected image from a DVD 
is split or otherwise scrambled. 
progressive scan mode.  Turn off progressive scan 
on the DVD player. 
Image is too bright and/or 
lacks definition in the bright 
areas of the image.  Contrast is set too high.  Lower the contrast setting. 
Image appears “washed out” 
and/or dark areas appear too 
bright.  Brightness is set too high.  Lower the brightness 
setting. 
Colors in the image are 
swapped; for example, reds 
appear blue or vice versa.  The Red/Pr, Green/Y or 
Blue/Pb outputs from the 
source are connected to the 
wrong inputs on the VHD 
Controller.  Ensure that the source 
outputs are connected to 
the correct VHD Controller 
input. 
Image geometry is incorrect. Incorrect aspect ratio 
selection. Select the aspect ratio that 
best matches the source 
image and screen size (refer 
to 
Table 4-1). 
The projector will not turn 
back on after it was powered 
down, or the image disappears 
during operation.  The projector will not turn 
on for two minutes after 
power-down, to protect the 
lamp. 
 
 The lamp has failed. 
 Wait two minutes until the 
STAND-BY LED at the front 
of the VHD Controller turns 
orange. 
 
 Replace the lamp.

6.1 
RS-232 Connection and 
Port Configuration
To interface the VHD Controller with a home theater automation/control system or a PC 
running terminal emulation software, connect it to your control system or PC as shown in 
Figure 3-16. Use a null-modem cable. 
If you are using a PC to communicate with the VHD Controller: 
1. Start a terminal session on your PC using a terminal-emulation program, such as 
HyperTerminal. 
2. Configure the PC serial port as follows: no parity, 8 data bits, 1 stop bit and no flow 
control. Set the baud rate to 19200, to match that of the VHD Controller RS-232 port.
3. Press . You should see a command prompt (>) in the terminal window. 
4. Type a command from among those listed in Table 6-1 and press . 
6.2 
Serial Command Syntax
 Commands are in ASCII format and are not case-sensitive; on and ON are equivalent. 
 For a command that takes no parameters, type the command followed by a carriage 
return; for example, to turn on the system, type ON. 
 For a command that takes a parameter, type the command, one or more spaces and the 
desired value followed by a carriage return; for example, to switch to the S-Video input, 
type SSRC
 1. 
 When you enter a valid command, the VHD Controller executes it. When you send an 
on/off, input selection, aspect ratio or image preset command, the VHD Controller also 
responds with an acknowledgment on the command line. For example, when you issue 
the command SAR
 2, the VHD Controller responds with Letterbox on the command 
line. 
 When you enter a misspelled or otherwise invalid command, the VHD Controller ignores it 
and responds with Invalid Command on the command line. 
 When you send a command followed by values outside the valid range for that command, 
the VHD Controller ignores it and responds with Invalid Parameter on the 
command line.
 When the VHD Controller receives an OFF command, it will not acknowledge or execute 
any commands for approximately 90 seconds afterwards. This is to prevent hot re-strikes 
of the lamp, which can damage it.
