No Signal
The message No signal present: check the source or connections to the
projector is displayed when there is no signal on the selected input. This means
that both HSYNC and VSYNC are inactive and the screen background is black.
Bad Sync
The message Bad Sync followed by a short description of the problem is
displayed when HSYNC or VSYNC are active but the signal cannot be
displayed. Such a condition occurs when only one of the two signals is present,
or when either signal is unstable or of the wrong frequency.
NOTE: Bad Sync or No Signal errors must be resolved in order to eliminate
the error message. In the meantime, press 
 to move the message down,
where it will remain until the error condition no longer exists. Other functions
remain operational.
Status LEDs
If the Status LED on the back of the projector repeatedly flashes a pattern of
yellow and red light while the Power LED glows a continuous red, you have
encountered a possible system error requiring the attention of a qualified service
technician. Contact your dealer or Electrohome if the problem persists.
The specific pattern of flashing indicates the 2-digit type code identifying the
type of problem detected — the number of yellow flashes represents the first
digit and the number of red flashes indicates the second. For example, a pattern
of yellow-yellow-red-red-red is Code 23. These codes include:
Code Description Code Description
11 General Fault 31 Unknown hardware failure
12 Software bug 32 MPM, VIM, or SPM faulty
13 CRC error in code 33 SPM, VIM, or VDM faulty
21 MPM self test failed 34 MPM or DMD faulty
23 SPM self test failed 35 I2C error
24 VDM self test failed 36 DMD lamp is overheating
25 VIM self test failed 41 RTC chip failure
26 DMD self test failed 42 RTC verify failure
27 DMD lamp has failed 61 COM software bug
Hard Reset
If the projector does not respond to anything and appears to have inexplicably
failed, gently push a very small screwdriver or pen point into the Hard Reset
hole just to the right of the power LED. This action will switch the projector off
(note that the power LED turns to yellow to indicate standby mode). Then
push 
 to turn the projector back on. Previously unsaved settings will be
lost. System Errors

Maintenance
VistaPro 2000 Users Manual 4-1
VistaPro 2000 is CSA approved and is designed for safe and reliable operation.
However, safe operation cannot be assured by design alone; installers,
maintainers, and users must maintain a safe operating environment for the
system. Please read through and understand the following warnings and
guidelines promoting safe usage of the projector.
WARNING
Never look directly into the projector lens.
The high brightness of this projector
(2000 ANSI lumens) could cause
permanent eye damage.
WARNING
For protection from ultraviolet radiation,
keep all projector shielding intact during operation.
Observe and follow all warnings and instructions marked on
the projector.
The exclamation point within the equilateral triangle alerts the
user to important operating and maintenance (servicing)
instructions in the literature accompanying the projector.
The lightning flash and arrowhead symbol within the
equilateral triangle alerts the user to uninsulated dangerous
voltage within the projectors enclosure that may be of
sufficient magnitude to constitute a risk of electric shock.
Operate the projector in an environment which meets the operating range
specifications in Section 5, Specifications. Do not operate the projector close to
water, such as near a swimming pool.
Do not place the projector on an unstable cart, stand or table. If
the projector is to be ceiling mounted, only use an
Electrohome-approved ceiling mount fixture.
A projector and cart combination should be used with care.
Sudden stops, excessive force, and uneven surfaces may cause
the projector and cart combination to overturn.

VistaPro 2000 Users Manual4-2
Do not operate the Xenon lamp for more than 750 hours; risk of the lamp
shattering increases as a result of changes in the quartz glass. Also, operation
beyond 750 hours significantly reduces brightness.
WARNING
Never attempt to remove the lamp directly after use. The
lamp is under great pressure when hot and may explode,
causing personal injury and/or property damage. Allow to
cool completely and handle by the plastic housing only.
The arc lamp operates at a very high temperature and
pressure. Failure to allow the lamp to sufficiently cool prior
to handling could result in an explosion causing personal
injury and/or property damage. After turning the projector off
it is important that you wait at least five minutes before
unplugging it. This provides enough time for the internal lamp cooling fans to
cool the lamp and to automatically shut off. Cool completely before handling.
Replace the right side filter every 750 hours or sooner. If this filter is not
replaced, air flow may become restricted and cause the projector to overheat.
See 4.4, Replacing the Lamp and Filter for the complete replacement
procedure.
WARNING
Only use filters supplied by Electrohome.
Only use attachments or accessories recommended by Electrohome. Use of
others may result in the risk of fire, shock or personal injury.
WARNING
Use only a special notched AC power cord. Do not attempt
operation if the AC supply is not within the specified voltage
and power range.
Do not allow anything to rest on the power cord. Locate the projector where the
cord cannot be abused by persons walking on it or objects rolling over it.
Operate the projector at the specified voltage. Do not overload power outlets and
extension cords as this can result in fire or shock hazards.
The projector is equipped with a three wire plug having a third (grounding) pin.
This is a safety feature. If you are unable to insert the plug into the outlet,
contact an electrician to have the outlet replaced. Do not defeat the safety
purpose of the grounding-type plug, and always use a notched power cord.
Before unplugging the power cord, make sure the internal
lamp cooling fans have shut off. The fans automatically shut
off when the projector has adequately cooled down.
Slots and openings in the projector provide ventilation. To
ensure reliable operation of the projector and to prevent overheating, these
openings must never be blocked or covered. The projector should never be Lamp and Filter

placed near or over a radiator or heat register. The projector should not be placed
in an enclosure unless proper ventilation is provided.
Do not push objects of any kind into the projector through the ventilation
openings. 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, unplug the projector from the power
outlet and refer service to qualified service personnel.
· The power cord has been damaged.
· The internal cooling fans do not come on when the projector is first turned on.
· Liquid has been spilled into the projector.
· The projector has been exposed to excessive moisture.
· The projector does not operate normally.
· The projector has been dropped or the case has been damaged.
· Projector performance has deteriorated.
Do not attempt to service the projector yourself. All servicing must be performed
by a qualified Electrohome service technician. If replacement parts are required,
it is important that only Electrohome-approved parts are used. Other parts may
result in fire, electric shock or risk of personal injury.
Clean the projector when required. Before cleaning, always unplug the projector
from the power outlet.
To avoid the risk of scratching the lens, only clean the lens if absolutely
required. A small amount of dust on the lens will have very little effect on
picture quality. If the lens must be cleaned, use a DRY soft cotton cloth. Rub
gently in a circular motion.
It is important to never touch the sapphire (glass) surface of the lamp, as the oil
imprint will seriously degrade lamp performance. Should you accidentally touch
the surface of the lamp, clean gently with a lint-free cloth moistened with
isopropyl alcohol.
Clean the case with a soft dampened cloth. Use a mild commercial cleaner. Do
not use liquid or aerosol cleaners.
The IR Remote Keypad uses four AA size, 1.5V alkaline batteries. To install
new batteries, open the battery compartment at the back side of the keypad by
pulling on the raised portion of the cover as shown (Figure 4.1)
Remove old batteries and properly discard. Place the new batteries in the
compartment, orienting the +/- of each battery according to the labels in the
compartment. When batteries are in place, replace the cover by inserting its
bottom edge first and snapping the top into place. Do not force. Servicing

The high brightness of VistaPro 2000 is provided by a 1 kilowatt Xenon lamp
permanently assembled in a sturdy polymer housing. When the lamp approaches
750 hours of usage this lamp module should be replaced. To determine how
many hours the lamp has been used, press 
 and go to the Status menu.
Current Lamp Hours indicates the number of hours logged on the lamp.
Contact your dealer or Electrohome for a VistaPro 2000 Lamp Assembly and
Filter Replacement Kit. You can specify either a new or refurbished lamp
module, both of which contain a new lamp bulb.
NOTE: As the lamp nears 750 hours of use, a lamp timer message can appear on
screen to warn that the lamp is in need of replacement. To make sure that this
warning appears, enter a checkmark in the Lamp Timer Message checkbox on
the Preferences menu.
WARNING
Never attempt to remove the lamp when it is hot. The
lamp is under great pressure when hot and may explode,
causing personal injury and/or property damage. Allow to
cool completely and handle by the plastic housing only.
Turn off the projector
Once you have turned off the projector, allow the cooling fans to automatically
turn off before continuing with Step 2. This will take about five minutes.
Unplug the projector
When the cooling fans have turned off, unplug the projector. Allow additional
time for the lamp to cool completely.
Remove both lamp doors
The lamp lies behind two doors on the far right of the projectors back panel.
First remove the outer lamp door cover by lifting up on the black latch (Figure 4.2).

Or, if you prefer, you can dispose of the old lamp as described below:
1.  For safe disposal, first relieve the pressure within the lamp module by
opening the lamp gas valve and allowing the Xenon gas to escape. This
valve lies beneath a small plastic seal protruding from the right end the
lamp (i.e., the end opposite the glass surface). To open the valve:
2.  Place the lamp module on a stable worksurface, with the glass lens
surface facing left as shown in Figure 4.7.
3.  Locate the plastic seal protruding
from the right side of the module—
the side opposite the lens (Figure
4.6). Remove this seal to expose the
valve screw underneath.
4. 
SLOWLY tighten the valve screw
until the lamp module begins to
hiss, signifying that the lamp seal is
broken and the Xenon gas is
escaping. Note that although this
gas is not harmful to the
atmosphere, always direct this surface of the module away from you and
others.
5.  Wait for the hissing to subside, which may take up to 20 seconds or more.
6.  Dispose of lamp with regular trash. Keep in mind that the integral lamp
timer contains a small amount of mercury—this mercury must be treated
as hazardous waste if discarded in volume.
Insert the new lamp module
Hold the new lamp module with the wire
handle facing you (the two brass nuts will
be on the opposing side). Make sure that
the glass lens surface is on your left —
otherwise the unit will be upside down.
See Figure 4.7
Ensure that the small plastic seal is intact
on the right side of the module (described
in Step 6, above
) — DO NOT REMOVE THIS
SEAL
.
WARNING
Take care not to touch the exposed surface of the
lamp itself — this could impair lamp performance
and shorten lamp life.
Carefully align the lamp module with the left side of the empty lamp
compartment. Push the module straight into the lamp area as far back as possible.

Then slide to right and push completely in (Figure 4.8). Push slowly but firmly
to ensure that the module is securely in place and is as far back as possible.
Figure 4.8. Insert new lamp module
Replace lamp retaining bracket
Insert the narrow end of the bracket into the slot on the right side of the lamp
compartment and push firmly to the right. Secure with two screws along the left
edge of the bracket.
Replace both lamp doors
Once the new lamp module is properly installed, replace the inner lamp door.
Insert the tabbed bottom edge first, then swing the top up and tighten the 2
screws. Replace the outer door by aligning the bottom edge and swinging the
door up into place. Pull the top latch of the door down.
Replace side filter
It is a good idea to replace the side filter whenever the lamp is replaced (or more
frequently if the operating environment is very dusty). This filter lies behind the
protruding grill on the side panel of the projector near the front corner (Figure
4.9). Unscrew the 2 screws from the bottom flange of the grill and remove the
grill and filter. Pull out the old filter and replace with the new, taking care that
the filter lies smoothly in place. Replace grill, tabbed end first, and secure with
screws.
WARNING
For safety, only use filters supplied by Electrohome.
Never operate the projector without
the filters installed.

Power up the projector
Plug in the projector and press 
 to turn it on. Allow the projector to warm
up for about five minutes.
Reset the lamp timer
In the Status menu, call up the Lamp Changed text box and enter the new lamp
serial number (see Section 3, Operation if you need help entering text). Once the
serial number is entered, the lamp timer will automatically reset to 0 hours and
begin to log time.
WARNING
If you neglect to enter a serial number, the lamp
timer will not reset to 0 and will therefore be
inaccurate. The lamp lifetime may then
prematurely expire.
NOTE: Once entered, the new lamp serial number is also automatically added to
the Lamp History list in the Service menu (password-protected). Lamp life
data is required for warranty claims.
A variety of VistaPro lenses are available to accommodate different throw
distances and specific types of installations. Contact your dealer or Electrohome
for more information.
Before removing or installing a lens, turn off the projector and allow to cool for
five minutes before unplugging. Make sure that the lens cap is on.
WARNING
 Always unplug the projector and allow to cool
before removing or installing a lens.
