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 VX-22i. 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.
stallation: 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). 
s: Select Lens from the Display Device menu to access the motorized lens 
controls. Refer to 
Primary Lens Adjustments on page 37. 
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. 
stic: 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 DHD 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 DHD 
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 47). 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 VX-22i 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 Runco CineWide with AutoScope system, assign at 
least one trigger output (the same one to which the lens motor is connected) to the 
Cinema and Virtual Cinema 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 VX-22i 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. 
Altitude: Select Altitude from the Miscellaneous menu to control the operation of the 
projector’s cooling fan. 
In most cases, the default setting (Normal) will maintain the correct operating 
temperature. If the lamp frequently turns off due to overheating, or in certain 
high-altitude operating environments, you may need to change this setting to High.
System Reset: To reset ALL projector 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.
This action is not undoable. Proceed with caution! Before you 
perform a System Reset, save your “Custom” ISF presets (
page 54) 
and ISF Day/Night presets (page 56).

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 Runco authorized 
service center or Runco 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.
 
 
 
5. Maintenance and Troubleshooting
The VX-22i 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 Runco 
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 VX-22i. If the suggested solutions fail to resolve the problem or if you 
encounter an issue not described here, please contact Runco Technical Support. 
Table 5-1. Troubleshooting Chart 
SymptomPossible Cause(s)Solution
The projector does not turn 
on after initial installation.  The VX-22i is not plugged 
in or the AC outlet is not 
active.  Ensure that the VX-22i is 
plugged in and that the AC 
outlet is active. 
The projector is 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.  DVD player is set to 
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. 
Blue/Pb outputs from the 
source are connected to 
the wrong inputs on the 
VX-22i.  Ensure that the source 
outputs are connected to 
the correct 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 disap
-
pears 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 rear 
of the projector turns 
orange. 
 
 Replace the lamp.

6.1 
RS-232 Connection 
and Port Configuration
To interface the VX-22i 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 
3-15. Use a null-modem cable. 
If you are using a PC to communicate with the VX-22i: 
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 VX-22i 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 VX-22i executes it. When you send an on/off, 
input selection, aspect ratio or image preset command, the VX-22i also responds with 
an acknowledgment on the command line. For example, when you issue the command 
SAR
 2, the VX-22i responds with Letterbox on the command line. 
 When you enter a misspelled or otherwise invalid command, the VX-22i 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 VX-22i ignores it and responds with Invalid Parameter on the 
command line.
 When the VX-22i 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.
