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. Contact your Vidikron dealer to 
obtain a replacement lamp.
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. Using a Phillips screwdriver, loosen the two 
Lamp Cover screws on the side of the 
projector and remove the cover.
 
 
 
 
 
 
 
 
3. Remove the three Phillips round-head lamp assembly mounting screws. These are 
identified by arrows pointing to them on the lamp housing.
4. Grasp the lamp assembly handle and pull gently, removing the lamp module from the 
projector housing.
5. Install the new lamp module. Secure it in place with the three screws that you removed 
in Step 3.
6. Replace the lamp cover and re-tighten the two Lamp Cover screws.
7. Re-connect the AC power cord to the projector.
8. Reset the Lamp Hour counter by doing either of the following: 
On the projector rear-panel keypad (see Figure 2-6), press and hold the ENTER, 
DOWN and RIGHT buttons simultaneously. Then, press the ON button. 
On the VHD Controller front panel (see Figure 2-3), while pressing and holding the 
ENTER button, press the POWER () button. 
When you do, “LAMP 0000H” appears on-screen to confirm the counter reset. 
5Maintenance and Troubleshooting
Always reset the Lamp Hour counter when you replace the lamp. Do this 
only if you have just installed a new lamp. This will ensure that number of 
hours logged on the lamp is accurate.

Troubleshooting Tips
Table 5-1 provides some general guidelines for troubleshooting problems you may 
encounter with the Vision 85. 
If you encounter an issue not described here or in Section 3 (refer to Installation 
Considerations on page 18), or if the suggested solutions fail to resolve the problem, please 
contact your Vidikron dealer or 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. 85 is not 
plugged in or the AC outlet 
is not active. 
 The serial connection from 
the VHD Controller to the 
Vision 85 is incorrect. 
 
 
 
 The remote control 
batteries have run out. 
 Ensure that the Vision 85 is 
plugged in and that the AC 
outlet is active. 
 Ensure that the RS-232 
output from the VHD 
Controller is properly 
connected to the RS-232C 
port on the Vision 85 (see 
Figure 3-6). 
 Replace the batteries. 
The projector and VHD 
Controller are both on, but 
there is no picture and 
on-screen menus do not 
appear.  Faulty or incorrect video 
connection between the 
VHD Controller and the 
Vision 85. 
 
 Ensure that the HDMI 
output from the VHD 
Controller is properly 
connected to the HDMI 
input on the Vision 85 (see 
Figure 3-6). 
The projector and 
VHD
 Controller are both on 
and menus appear on-screen, 
but there is no picture. 
 Incorrect source selection. 
 Source component is not 
turned on. 
 Source component is 
connected incorrectly or 
not at all. 
 Select the correct source. 
 Turn on the source.  
 Check video connections to 
source component. 
A projected image from a DVD 
is split or otherwise scrambled.  DVD player is connected to 
the Component input and 
set to progressive scan 
mode.  Turn off progressive scan 
on the DVD player. Or, 
connect the DVD player to 
the HD1 or HD2 input. 
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) on 
one or more sources.  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. 
 
 
 Image height may need 
adjusting (Vision 
85/CineWide only). 
 Select the aspect ratio that 
best matches the source 
image and screen size (refer 
to 
Table 4-1). 
 Adjust displayed image 
height (refer to 
Display 
Device on page 49). 
The projected image is 
trapezoidal in shape.  The projector is not 
perpendicular to the 
screen.  Adjust the projection angle. 
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 or 
reached its usage limit of 
2000 hours. 
 Wait two minutes until the 
LED at the front of the VHD 
Controller turns red. 
 
 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 3-11. 
Configure the RS-232 controller or 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. 
6.2 
Serial Command Syntax
Serial commands to the VHD Controller take the following form:
 Commands are not case-sensitive. 
 For a single command that takes no parameters, type the command followed by a 
carriage return; for example, to set the aspect ratio to Letterbox, type 
LETTERBOX
 . 
 For a single command that takes a parameter, type the command, a space or a comma 
and the desired value followed by a carriage return; for example, to set the brightness to 
-10, type BRIGHTNESS
 -10  or BRIGHTNESS,-10 . 
 You can also send a string of multiple commands on a single line, separated by commas. 
For example, COMPOSITE,BRIGHTNESS
 100,ANAMORPHIC  switches to 
the Composite video input, sets the brightness to 100 and sets the aspect ratio to 
Anamorphic. Command strings can be up to 255 characters long. 
 
Table 6-1 lists the RS-232 command set. The “Parameter (min/max)” column shows the valid 
parameter ranges, or “NA” for commands that take no parameters. 
When you enter a valid command, the VHD Controller executes it and acknowledges it with a 
plus sign on the command line (+ >). When you enter an invalid command – one that is 
misspelled or followed by values outside the valid range for that command – the VHD 
Controller ignores it and returns a minus sign (- >). 
 
6Serial Communications
Avoid combining the ON or POWER 1 commands with other commands on a 
single line. After sending ON or POWER 1, allow at least 15 seconds for the 
VHD
 Controller to power up. Once it does, it will accept and properly execute 
multiple serial commands.
