Slots and vents in the projector provide ventilation. Never block or cover these openings. 
This ensures reliable operation of the projector and prevents overheating.
•   Do not place the projector over a radiator or heat register. The projector should 
not be placed in an enclosure unless proper ventilation is provided.
•   Do not insert objects into the ventilation openings of the projector. They may 
touch dangerous voltages or short-out components resulting in a fire or shock 
hazard. Do not spill liquids of any kind into the projector. Should an accidental 
spill occur, immediately unplug the projector and have it serviced by a qualified 
service technician.
If any of the following conditions exist, immediately unplug the projector from the power 
outlet and ask a qualified service technician to look at it.
•  The power cord has been damaged.
•  The internal cooling fans do not turn on within two minutes when the projector  is first powered up.
•  Liquid has been spilled into the projector.
•  The projector has been exposed to excessive moisture.
•  The projector is not operating normally or its performance has significantly 
deteriorated in a short period of time.
•  The projector has been dropped or the shipping case (if applicable) has been 
badly damaged. WARNING
Do not attempt to service the projector yourself. All servicing must be  performed by Runco accredited service technicians.
Use replacement parts that are manufacturer-approved only. Use of any 
other part other than the ones specified by the manufacturer can result  in fire, electric shock or other damage.

Section 4: Maintenance

WARNING
Always power down and unplug the projector before cleaning or  servicing.
Part 
Description Frequency 
Action
Lens As required CLEAN: Clean if absolutely necessary. A small 
amount of dust on the lens has very little affect 
on picture quality.
To clean:
 Apply a solvent such as acetone, 
alcohol or vinegar sparingly to clean, lint-free 
lens tissue. Wipe across the surface of the lens. 
Do not scrub or rub tissue in circular motion, this 
will scratch the lens. Do not reuse tissue. Do not 
use cleaning tools treated with Ether. If particles 
still appear on the lens, try using compressed air 
to remove.
Lamp As required CLEAN: Clean if absolutely necessary. Never 
touch the glass surface of the lamp. Fingerprints 
left on the glass will seriously degrade lamp 
performance or cause “hotspots” which can 
lead to an accumulation of intense heat in the 
touched area and cause the lamp to shatter. 
To clean: Wait until lamp is cool. Moisten a 
clean, lint-free cotton cloth with isopropyl alcohol 
and gently rub the surface of the glass in a 
circular motion until clean.
1000 hrs or 
sooner if required 
REPLACE: Refer to 4.4 Lamp Replacement 
procedure later in this section.
Covers 
(External)As required CLEAN: Clean dust from external covers using a 
clean, lint free cotton cloth as required. 
NOTE: Before cleaning the modules, it is 
recommended that you install the lens cap. This 
will keep dust particles from settling on the glass 
surface of the lens.

The optional IR remote uses four AAA size, 1.5V alkaline batteries. To replace the batteries 
simply turn the remote over and remove the battery cover.
Remove and properly discard the old batteries. Insert new batteries in the proper positive/
negative orientation as shown etched in the bottom of the compartment (2). Replace the 
cover  by  inserting  the  tabbed  end  into  the  opening  and  snapping  the  opposite  end  into 
place.
Use the following instructions when replacing the lamp. The lamp is located at the back of 
the projector (below the input panel) and can be accessed by removing the lamp access 
panel. Use only the Runco approved 
Lamp and Filter Kit for your specific projector model.

A lamp should be replaced when it reaches its end of life (1000 hours, typical) or 
sooner if a noticeable degradation in brightness occurs (typical in aging lamps). You 
can set the number of hours you expect to log with the lamp before replacing it, by 
setting the Lamp Limit  in the Lamp menu. You can also enable a warning message 
to appear upon powering up the projector that will indicate the lamp has reached the 
limit you set, by entering a checkmark beside the  Lamp Message option. NOTE: The 
lamp mode you choose to run the projector in may affect the lamp life.

Section 4: Maintenance

Use the following instructions when replacing a projection lens:
NOTE for first time use: The projection lens is shipped separately from the projector. 
Before you install a lens it is important that you remove the lens plug from the lens 
opening in the projector.
1.  Power  down  the  projector  and  wait  five  minutes  to  allow  the  lamp  to  cool  before 
continuing with Step 2.
2.  Place the lens cap on the projection lens to protect it from being damaged during the  installation  or  removal  process.  For  first  time  installations,  remove  the  rear  cap  from 
the  lens  –  this  protective  cap  is  only  used  during  shipping  to  protect  the  lens  from 
damage.
3.  When  removing  the  projection  lens  –  Press  and  hold  the  “lens  release”  button 
located  in  the  top  right  corner  of  the  lens  panel.  Grasping  the  lens  barrel,  turn  it  in  a 
counter-clockwise direction until it stops. Then pull it forward to remove it (disconnects 
from the connector assembly).
OR
When  installing  a  projection  lens,  make  sure  Steps  1  and  2  are  complete.  Slide  the 
new lens into the lens opening of the projector – make sure to align the connector that is 
located on the side of the lens with the connector assembly on the lens retaining ring. As 
you connect the lens, you may have to re-align it slightly until the tabs on the lens will fit 
into the slots in the lens retaining ring. With the lens fully inserted (and connected) turn it 
clockwise until the lens release button “pops” indicating the lens is fully inserted.

Troubleshooting
SECTION 5
If  the  projector  does  not  appear  to  be  operating  properly,  note  the  symptoms  present 
and  use  the  following  guide  to  assist  you.  If  you  cannot  resolve  the  problems  yourself, 
contact your dealer for assistance.
NOTE: A qualified Runco service technician is required when opening the projector to diagnose any “probable cause”.
5.1 Displays
SYMPTOMCAUSE/REMEDY
The projector is on but 
there’s no display... Was a lens cover accidentally left on? Remove lens 
cover.
Make sure the shutter is OPEN.
Is the lamp ignited? Check for interlock problems such 
as an open lamp door OR check for light spillage out the back.
Is the correct input selected? Check cable connections.
Check if menus appear on screen.
Can  you  access  test  patterns?  Make  sure  there  is  not  a 
full  black  test  pattern  selected  for  display—press  Menu 
to  access  test  patterns,  then  cycle  patterns  with  keys. 
Check your source connections again.
Severe motion 
artifacts... Most likely there is a synchronization problem with 
reversed 3/2 pull-down in 60Hz-to-24Hz film-to-digital 
conversion in your source. Correct at the source.
Was an excessive amount of keystone used?
Image appears “squeezed” or vertically 
stretched into center of 
screenCheck your Resizing selection.
Check the DHD Controller’s aspect ratio selection.
The display is jittery or unstable...  If the display is jittery or blinking erratically, ensure that 
the source is properly connected and of adequate 
quality for detection. With a poor quality or improperly 
connected source, the projector will repeatedly attempt 
to display an image, however briefly.
The horizontal or vertical scan frequency of the input 
signal may be out of range for the projector. Refer to 
Section 6, Specifications for scan frequency ranges.
The sync signal may be inadequate. Correct the source 
problem.
The display is faint...Brightness and/or contrast and/or gamma may be set 
incorrectly.
 The source may be double terminated. Ensure the 
source is terminated only once.
The source (if non-video) may need a different sync tip 
clamp location.
The upper portion of 
the display is waving, 
tearing or jittering... This  can  sometimes  occur  with  video  or  VCR  sources. 
Check your source.

Section 5: Troubleshooting

SYMPTOMCAUSE/REMEDY
Portions of the display 
are cut off or wrap to 
the opposite edge...
Resizing and/or blanking may need adjustment.
The horizontal or vertical scan frequency of the input signal 
may be out of range for the projector. Refer to Section 6, 
Specifications for scan frequency ranges.
The display appears 
compressed ...
The  aspect  ratio  selected  at  the  DHD  Controller  may  be 
incorrect.
 Resizing,  vertical  stretch  and  positioning  options  may 
be  improperly  adjusted  for  the  incoming  source  signal. 
(Example:  The  DVD  player  is  set  for  the  wrong  screen 
type.)
Data is cropped from 
edges
Check settings for Blanking.
 If  incoming  data  is  still  missing  from  the  image,  reduce 
the  image  size  to  within  the  display  area  available  in  the 
projector.
Display quality 
appears to drift from 
good to bad, bad to 
good... The source input signal may be of low quality.
The display has 
suddenly frozen...
It’s possible that excessive voltage noise on the AC or 
ground input has interrupted the projector’s ability to lock 
on to a signal. Power down the projector and disconnect 
from AC. Then plug in again and power up as usual.
Colors in the display 
are inaccurate...Try Auto Setup.
 The color, tint, color space, color temperature and/or 
other settings may require adjustment.
Ensure signal connections are correct.
Make sure you are using the proper channel for this 
source.
Values in Color 
Saturation slidebars 
vary over time...  Once defined, Color Saturation slidebar values fluctuate 
over time and will likely be different upon subsequent 
visits to this menu. This is normal and should be ignored, 
as these changes do not redefine the x/y coordinates or 
color gamut.
The display is not 
rectangular...
 Check leveling of the projector. Make sure that the lens 
surface and screen are as parallel to each other as 
possible.
The display is 
“noisy”...Display adjustment at your input source may be required.
 The  video  input  may  not  be  terminated.  Make  sure  the 
video input is terminated (75
Ω). If it is the last connection in 
a loop-through chain, the video input should be terminated 
at the last source input only.
 The  input  signal  and/or  signal  cables  carrying  the  input 
signal may be of poor quality.
 If  the  distance  between  the  input  source  device  and  the 
projector  is  greater  than  75  feet,  signal  amplification/
conditioning may be required.
If  the  source  is  a  VCR  or  off-air  broadcast,  detail  may  be 
set too high.
