General

Information

1. PRODUCT OVERVIEW

With 1500 lm brightness, XGA resolution, and weight of 2.9 kg, this projector is in the

micro-portable class.

It features the highest zoom ratio for its class (1.6×), the ratio that has had proven
results in the standard series. Above projection lens enables 100-inch projection from
only 2.5m away.

Equipped with image input and system functions actualized in a part of the models
launched after the LV-X2, such as 2-3 pull-down, this model also has new features
including blackboard mode and security functions that have been incorporated for the
first time ever in a Canon projector.

Fig. 1-1 Exterior of LV-X4

Part 1: General Information

1-1

2. MAIN FEATURES

● XGA and achieving 1500 lm

A 200 W SHP lamp has been adopted. The projector is compact and lightweight

(micro-portable), and XGA achieves a bright display of 1500 lm.

● A4-file size, 2.9 kg

With the compact body achieved through space-saving design, we were able to reduce

projector weight to 2.9kg. Together with the color, Frosty White Pearl, this gives the

projector a feeling of quality and lightness.

● 1.6x wide zoom lens (highest zoom ratio for its class) projecting 100 inches at 2.5 m

The compact wide zoom lens, with its proven results, utilizes two aspherical lenses

(one on each end) and one UD lens with anomalous dispersion characteristics.

Having the highest zoom ratio in its class, 1.6×, and the lens not only enables 100-

inch, large-screen projection from only 2.5m away but also produces high-quality

images with color bleeding curbed.

● Accommodates 2-3 pull-down (480i)

When there is 480i component signal and NTSC composite signal input, this function

automatically identifies input signals that have been converted from Cinema to

television image signals and faithfully converts them to progressive display.

● Blackboard mode

Added to the conventional image mode, this new mode was created for projection on

blackboards (in green). Mere selection of the dedicated video reproduction mode

makes it possible to approximate natural color tone.

● Security function

Setting a password makes it possible to institute usage restriction.

When this function is used, the password will be required when starting up the

projector and modifying the startup logo.

● Lamp modes

These products come with three lamp modes — Normal, Silent, and Auto — that allow

users to switch the lamp's brightness.

The Normal Mode prioritizes brightness, the Silent Mode runs quietly at 35 dB by

lowering the fan speed, and the Auto Mode improves the reproduction of black by

adjusting the lamp's output to suit the scene.

● Fan setting when power is off

Cooling fan operation when power is off can be set to high-speed revolution (for 90 sec)

or standard revolution (for 120 sec). With standard revolution, fan noise will not

become loud when the lamp is off, which is convenient in many cases, such as when

continuing a meeting with the lamp off.

be used due to the frequency of the input signal or the type of computer. (See the owner's
manual for details)

• Analog RGB

Display resolutions: SXGA (compressed), XGA, SVGA, VGA, MAC

• Multi-scan system

The projector recognizes the horizontal and vertical frequencies of the image signal
from the connected computer and automatically selects the corresponding display
system.

• Automatic PC adjustment

This function can be set to automatically adjust the number of horizontal pixels,
tracking, and screen position of the picture.

● Component video input

• Scanning systems
These products support 1080i, 1035i, 720p, 575p, 575i, 480p and 480i. (Auto and
manual selection)

● Composite video input or S-Video input

MODE Normal Silent Auto

LAMP POWER 190 W 168 W Fluctuate

Noise 38 dB 36 dB Fluctuate

Brightness 1500 lm 1275 lm Fluctuate

The Normal Mode is used to project with brightness priority. The Normal Mode is
appropriate for large meeting rooms or in situations where the room cannot be
darkened.
The Silent Mode lowers the noise level by reducing the brightness. The Silent Mode is
appropriate for small screens or in situations where lower light output is sufficient.
The Auto Mode automatically varies the output of the light source. The Auto Mode
adjusts the lamp's output according to the brightness of the scene. The Auto Mode
reproduces dark scenes in a movie with an emphasis on the black component.

● Audio Mute

This function temporarily turns off the output to the speaker.

* The projectors have a built-in 1-watt speaker. Audio from computers or VCRs is

played back in monaural.

● Adjustable feet

These products come with two adjustable feet at the front heel of the unit under the
projection lens side to tilt the unit. By adjusting these feet's height, the slant of the
projection can be changed easily. The projection axis can be slanted as much as 11.9
degrees from the surface the projector is placed on.
With one movement, the adjustable foot can be unlocked and stored inside the
projector body.

* Distortions in the picture's shape when the projector is tilted can be corrected using

the previously mentioned keystone correction function.

● Power management

This function turns the lamp off if no video signal is input or projector operation
performed for a preset period.
This duration can be set between one and 30 minutes.
When the lamp has been turned off with power management, it will automatically
turn on when a video signal is input again or a projector operation performed. (Note
that the lamp will not turn on during the cool down period effective immediately after
being turned off.)

* If you select [Ready], this only switches off the lamp, and if you select [Shutdown]

this switches off the power.

7. PRECAUTIONS FOR USE

● Do not unplug the projector after turning off the lamp until the cooling fan stops.

Not allowing the projector to cool sufficiently may damage the unit.

* The hot lamp will cause burns. Wait at least 45 minutes after the fan stops before

replacing the lamp.

● Always use the LV-CL08 ceiling attachment when mounting the projector to a ceiling.

The projector may fall or be damaged if mounted with a mounting bracket intended
for a different model.

● Do not look directly at the projection lens when it is in operation.

The projection is very bright and can damage eyesight.

● Replace the lamp with a new lamp promptly when lamp replacement is indicated.

A high-pressure mercury lamp is used as the projector's light source. Due to the
characteristics of the mercury lamp, it may burst because of deterioration over long
use.
Should the lamp burst, we recommend that you return the projector to the store
where you purchased it to have the lamp replaced and the unit inspected.

● Do not use the projector when tilted excessively.

Place the projector on surfaces with a horizontal slant of no more than ±20 degrees.
Due to the characteristics of the mercury lamp, using the projector at an excessive
inclination may cause the lamp to operate abnormally or shorten its service life.
The projector was not designed to be used while tilted; therefore, use the projector on
a level surface whenever possible.

8. DESCRIPTION

8.1 Optics

This product adopts the features of the LV-7215 and other zoom lenses, the aperture
ratio of the LCD panel is large, a 0.79 type (nominally 0.8 type), and the size has been
reduced while achieving high luminosity with a 200 W SHP lamp.

● 1.6× wide zoom lens (Same as LV-7215/7210/5210)

This product incorporates a projection lens that has a first rate zoom ratio of 1.6×

magnification. Constructed of 11 layers in 11 groups, this is a 6-group zoom lens in
the configuration: Neg./Pos./Pos./Neg./Pos./Pos.
By using an aspherical lens (G2, G10) on both sides, the front lens is much smaller
and the number of lenses has been reduced, resulting in the realization of a more
compact wide-angle lens. Also, by using one UD lens (G9) with its error dispersal
characteristics, the occurrences of color aberrations have been suppressed while
achieving high pixelization.
In consideration of the environment, all the glass in the optical system is lead free.

● Projection distance (Same as LV-7215/7210/5210)

This product can display images with excellent fidelity on 100-inch screens at a throw
distance of 2.5 m.
Refer to the table below for the relationship between the throw distance and the screen
size.

* The projector displays correctly at screen sizes between 40 and 300 inches; the quality of

projections at other screen sizes is not guaranteed.

● LCD panels

This product consists of opposing 20 mm (0.79 type) LCD panels (without micro­lenses).
The capacity is essentially the same as the LV-7210.

● Lamp

This product adopts as its light source the 200 W SHP lamp to achieve luminance of
1500 lm.
However, the output is set to 190 W in order to balance luminance, production of heat,
and power consumption.

8.4 Mechanisms and Systems

The mechanism of this product, including external dimensions, is almost the same as

that of the LV7215.

● Lowering Temperature and Reducing Noise

To control temperature, this product has adopted the following features: enlargement
of the punching diameter of the ventilation port, changing the lamp duct, changing
the fixture that anchors the ventilation fan, and changing the power source holder.
These improvements make it possible to reduce the number of fan revolutions and
lower the level of fan noise.
Also, in addition the reduction in the number of fan revolutions mentioned above, a
himelon sheet is spread in the interior to baffle spurious noise from the front, and
cushions have been added near the ventilation ports on the sides to suppress
vibrations.
Compared to the current mode (LV-7215), this product achieves a reduction in
spurious noise of approximately 1.5 dB when operating in the Lamp Normal mode.

8.5 Design (Same as LV-7215/7210/5210 except for the underlined part)

These projectors continue the design concepts of Canon's power-projector series: an
intelligent and beautiful appearance; a solid three-dimensional form refined to the finest
detail; and the look and feel of an optical instrument. Canon's designers also aimed for a
next-generation standard of simplicity and transparency that creates an approachable
and agile impression.

● Styling

These products were styled to suit a variety of situations: from private living rooms to
office environments particular about interior design and retail stores where projectors
are used for promotional purposes.
The main unit employs an "air-style form", featuring a clean surface construction and
simple molded elements that blend naturally into the installation space. The
translucent operation panel, fashioned in the shape of a jellybean, accentuates the
overall style. Also, attention was paid to the surface finish and key layout so that
users can find their way around the operation panel just by touch in low-light
situations.

● Color scheme

Not used for the conventional models, Frosty White Pearl, the new body color,
engenders feelings of high quality and transparency.
* The initial LV-7215 models were given a double coat of paint. However, to simplify

the manufacturing process and reduce costs, later models were given a single coat,
giving them a different look.
Like the LV-7215, a later model, this product was also given a single coat.

● Details

The optical engine is protected from impacts by encasing the focus ring with a

cylinder, thereby keeping unforeseen accidents from disrupting a presentation.

Furthermore, a more comfortable operating environment is created by placing the

exhaust vent on the same side as the projector lens, keeping exhaust heat and fan

noise away from people.

The punched metal cover, which encloses the exhaust vent, air intake, speaker, and

remote-control sensor window, gives a simpler, more stylish look than the former

blind-shaped louvers.

All connectors that users need to access are placed on the back panel.

By using luminous materials for the switches and giving a mirror finish to the base,

the standard remote control can be seen and used accurately in dark or poorly lit

conditions.

1. SAFETY INSTRUCTIONS

The following precautions must be observed during servicing and inspection.

Observe all safety precautions.

Comply with all caution and safety-related notes provided on the cabinet back, cabinet
bottom, inside the cabinet, on the chassis or components, as well as the precautions
shown in the instruction manual during servicing.

Avoid electric shock.

Since an AC voltage is applied to the chassis for the set, touching the chassis during
power-on may cause electric shock. When service is performed during power on, use an
insulation transformer, wear protective gloves, and remove the plug during parts
replacement. As there are high-voltage areas inside the projector, handle it with care
when the power is on.

Use specified parts.

The parts of the set have safety properties, such as inflammability and voltage
withstand. Therefore, use replacement parts with the same characteristics as the
original ones. The critical components for safety are indicated by mark in the schematic
diagram and parts list must be replaced by the recommended parts.

Reinstall parts and wires in their original positions.

Insulating materials, such as tubes and tape, are used and some components are
installed over a PC board for safety. Reinstall internal wires with clamps so that they do
not touch any heat-generating or high-voltage parts.

Safety c

heck after service

Verify that service locations are not deteriorated and all removed screws, parts and
wires are installed in their original positions. In addition, perform the following test to
ensure safety.

Insulation resistance test method

Remove the plug from the electric outlet and press the power switch. Using a 500V
insulation resistance tester (or a multimeter if any insulation resistance tester is not
available), check that the insulation resistance between each terminal of the plug and
external exposed connector (external speaker connector, remote control connector, AV
input/output connector, etc.) is 1Mohm or higher

. If not, the set must be inspected and

repaired.

Components indicated by mark in the parts list and the schematic diagram designate components in
which safety can be of special significance. It is, therefore, particularly recommended that the
replacement of there parts be made by exactly the same parts. Using unspecified parts may worsen
failure or cause fire or electric shock.

Eye damage may result from directly viewing the light produced by the lamp used in this equipment.
Always turn off the lamp before opening the cover.
Never turn the power on without the lamp to avoid electric shock or damage of the devices since the
stabilizer generates high voltages (2kV - 3kV) at its starts.
Since the lamp is very high temperature during units operation replacement of the lamp should be done at
least 45 minutes after the power has been turned off, to allow the lamp cool-off.

2. CIRCUIT PROTECTIONS

This projector provides the following circuit protections to operate in safety. If the
abnormality occurs inside the projector, it will automatically turn off by operating one of
the following protection circuits.

2.1 Fuse

A fuse is located inside of the projector. When the
POWER indicator is not lightning, the fuse may be
opened. Check the fuse as following steps.
The fuse should be used with the following type;

[Fuse replacing steps]

1. Remove the cabinet top and cabinet front following

to “Mechanical Disassemblies”.

2. Replace the new one with the specified type.

2.2 Thermal Switch

There is the thermal switch (SW902) inside of the
projector to detect the internal temperature rising
abnormally. When the internal temperature reaches
near 90˚C, it cuts off the AC main power supply.

The thermal switch cannot be reset itself
automatically even if the internal temperature
becomes normal. Reset the thermal switch following

2.4 Warning Temperature and Power Failure Protection

The projector will be automatically turned off when the internal temperature of the
projector is abnormally high, or the cooling fans stop spinning, or the power supplies in
the projector are failed.

• If the WARNING indicator is flashing, it may detect the abnormal temperature inside

the projector. Check the following possible causes and wait until the WARNING
indicator stops flashing, and then try to turn on the projector.

• If the WARNING indicator lights red, it may defect the cooling fans or power supply

circuits. Check fans operation and power supply lines referring to the chapter “Power
supply & protection circuit” in the Chassis Block Diagram section.

[Possible causes]

• Air filters are clogged with dust particles. Remove dust from the air filters by following

instructions in the “Air filter care and cleaning” below.

• Ventilation slots of the projector are blocked. In such an event, reposition the

projector so that ventilation slots are not obstructed.

• Check if projector is used at higher temperature place (Normal operating temperature

is 5 to 35˚C or 41 to 95˚F)

2.5 Air Filter Care and Cleaning

The removable air filter prevents dust from accumulation on the surface of the
projection lens and projection mirror. Should the air filter become clogged with dust
particles, it will reduce the cooling fan’s effectiveness and may result in internal heat
build up and reduce the life of the projector.

To clean up the air filters, follow the cleaning
procedure below:

1. Turn the power off, and disconnect the AC

power cord from the AC outlet.

2. Turn the projector up side down and remove

air filters by pulling the latches of it upward.

3. Clean the air filters with brush or wash out

the dust and particles.

4. Replace the air filters properly. Make sure

that the air filters are fully inserted.
