VCCI COMPLIANCE STATEMENT
This equipment has been tested and found to comply with the limits for Type 1 information equipment, which uses
radio-frequency energy and fully complies with the specifications limiting computer information equipment in radio
interference regulations (VCCI rules). If not installed and used properly according to the manufacturer's instructions,
this device may cause interference to radio and television reception. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause interference to radio and television reception,
which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference
by one or more of the following measures:
❑
Reorient or relocate the receiving antenna
❑
Increase the separation between the equipment and receiver
❑
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected
❑
Consult the dealer or an experienced radio/TV technician for help.
The user may find the following booklet, prepared by the Federal Communications Commission, helpful: How to
Identify and Resolve Radio-TV Interference Programs. This booklet is available from the U.S. Government Printing Office,
Washington, D.C., 20402, Stock No. 044-000-00345-4.
You can determine whether your computer is causing interference by turning it off. If the interference stops, it was
probably caused by the computer or its peripheral devices. To further isolate the problem, disconnect either the
peripheral device or its I/O cable.
These devices usually require a shielded cable. For EPSON peripheral devices, you can obtain the proper shielded
cable from your dealer. For non-EPSON devices, contact the manufacturer or dealer for assistance.
WARNING
Only peripherals (computer input/output devices, terminals, printers, etc.) certified to comply with the Class B limits
may be attached to this projector. Operation with non-certified peripherals is likely to result in interference to radio
and TV reception. The connection of a non-shielded equipment interface cable to this equipment will invalidate the
FCC Certification of this device and may cause interference levels that exceed the limits established by the FCC for
this equipment. Changes or modifications not expressly approved by the manufacturer could void the user’s
authority to operate the projector.

EPSON PowerLite 5000 Service Manual
1.1 PRODUCT FEATURES
The PowerLite 5000 multimedia projector is a portable, easy-to-use presentation device
with an SVGA resolution. It projects enhanced color images from personal computers and
from video equipment such as VCRs, camcorders, and digital cameras.
Features
❐ Light weight, compact, portable
The new structure minimizes the projector to page size with a weight of only 14.1 lb
(6.4 kg). An optional carrying case is available for transporting the projector.
❐ Bright and clear images
The high performance zoom lens, new, bright lamp (400 lm. ANSI), and optical block
provide a wide image of 21" to 300" (1.2 to 12.3 m). An optional brightness screen
provides clear images, even with bright ambient light.
❐ High resolution full color (16770 thousand colors)
Three (R, G, and B) TN liquid crystal panels of 480,000 pixels support an SVGA
resolution of 800 x 600. The grid between pixels in the liquid crystal panel is thinner
than that of conventional projectors, providing sharp contrast.
❐ Remote control
You can control the projector using a hand-held remote control unit that has menus for
image source switching and image adjustment. The remote control can also work as a
wireless mouse during presentations. The ELP LINK IITM software has
add-on features that make presentations effective.
❐ Connectivity with various types of computers
The projector can connect to various types of computers such as IBM-compatible PCs,
laptops, and Macintosh computers. It also differentiates NTSC, PAL, or SECAM video
signals in composite video or S-Video format.
❐ Advanced Image Real-time Resizer
The projector features a new, patent-pending SizeWise chip that supports SVGA
computer output, as well as VGA and XGA output. No matter what type of output is
used, the result is a full-size video image of outstanding clarity.
❐ Automatic video tracking
A totally new AVTSSTM (Automatic Video Tracking and Synchronization Sensing,
patent pending) feature provides automatic setup of images from the computer with a
touch of the AUTO button for quick and easy projection of images.
❐ Simple maintenance
The maintenance is easy. The image adjustment process has been minimized.
❐ Theft - proof
A Kensington lock that attaches to the lower case is available.

Description of the Projection Process
1. The digital or analog R/G/B signal is provided from a computer (1 or 2) to the main
board. Analog signals (S-Video or Video signals) are sent to the main board through the
AU board. (Analog signals are converted into digital signals by the main board.)
2. The digital video signal is then stored in video memory (SRAM) on the main board.
Then the driver board generates signals to drive the R/G/B light valves.
3. The R/G/B light valves are individual panels, independent of each other. They work to
shut off or transmit lights from the light guide unit.
4. Lights transmitted through the light valves are combined by a prism and projected
through the lens unit.

2.2 POWER SUPPLY UNIT
The power supply unit includes a DC regulator, intake fan, and interlock switch for the
lamp cover. This unit generates the voltages for the control circuit (+3.3 V, +5 V, +12 V,
+22 V) and for the light source lamp (+350 V) from AC input.
The PBS thermistor is installed on the side of the power supply intake fan and is retained
with a clamp on the power supply unit. It detects the temperature. If it senses overheating,
it shuts off the regulator output via the main board. Although a functional diagram is shown
below, never disassemble the power supply unit at field maintenance service.

The power supply cable is connected to CN800 on the main board. The following items
are also connected to CN800:
DC output line
PWDS signal for the power on/off control
Lamp power on/off control signal (LPSTC)
Background power (+3.3 V) on/off signal (BACTA)
Caution:
If the AC power cable is still connected after the power is shut off, +3.3 V background
voltage is supplied to the main board via CN800 and power on/off circuit.

•
The filter/rectification circuit reduces noise on the AC line and generates DC voltage for
the regulator.
The regulator generates the various DC voltage levels shown in the table below for the
switching regulator. The regulator detects the voltage output level at the +5 V line and
feeds the information back to the switching circuit to maintain a stable output level
regardless of load variations. Not every output voltage level is subject to adjustment.

IC600 and related circuits are backed up with +3.3 V which is provided from the power
supply. (If the AC cable is connected to the AC source, power supply provides the
+3.3 V for back-up bias even if RS-361 is turned off.)
When the power is turned on, IC600 on the main board generates the reset signal and
initializes the circuit. The CPU reads the program from flash ROM and writes it into
SRAM. Then the CPU sets the functions based on the program and projects the initial
image.
Three thermistors (LV Thermistor / Lamp Thermistor / PBS Thermistor) detect
temperature. If the temperature exceeds a predefined level, the thermistors send an
interrupt signal to IC600 and shut off the power supply.
Computer analog or digital input signals are converted into analog signals first, then
converted to digital signals again by ADC. These display data written into the video
memory (SRAM).
Analog output signals are transmitted in different ways for analog input and digital
input.
1. Digital RGB:
The digital image signals are output via the gate and driver board.
2. Analog RGB
The analog image signals are converted by the ADC and the D/A converter.
The data is stored in the SRAM, then output for display to the video controller via the
CPU.
Video input signals are transferred via the AU board and converted into digital signals
with the A/D converter. They are stored in the SRAM.
The projector has a timer circuit that controls the operating time of the light source bulb
(lamp inner housing). Its operation is described below.
Table 2-5
Light source state
When the operating time of the light source
bulb (lamp inner housing) exceeds 1900
hours.
When operating time of the light source bulb
(lamp inner housing) exceeds 2000 hours.
When the light source bulb (lamp inner
housing) runs out before its expected end of
life.
Lamp monitor state
The lamp monitor continues to flash red and
orange for 5 minutes after it is turned on. (The
light source stays on.)
The lamp monitor flashes green and orange.
(The light source goes off.)
The lamp monitor flashes red.
If you observe the conditions above, replace the light source bulb (lamp inner housing).
Then turn on the switch. The fuse in the lamp will melt and short out, so that the lamp timer
will be reset automatically.

2.4 DRIVER BOARD
The driver board has two functions: one is converting the R/G/B display signal from the
main board into six states of analog signals (light valve driver signals) and the other is
controlling the display image by referencing electrical correction data.
The entire optical engine must be replaced in maintenance service. No individual parts,
such as the driver board, may be replaced. The fuses listed below are soldered onto the
Driver board. They are not replaceable and are listed for reference only. Please refer to

the driver circuit for the light valves.
Timing signals output from the display controller are converted into signals for the light
valves (LCDs) by the D/A converter and LCCOM circuit before they are output.
•
The filter/gate circuit is designed to reduce noise influence on the display driver circuit.
To reduce impulse noise, input signals are sent through the three-level filter circuit. To
reduce the effects of timing delays on the logic, gate circuits work as trigger circuits for
each signal line (R/G/B) and unify the output timing.
•
The flash ROM contains electrical correction data for the image display. The display
controller reads the correction data. The controller uses the correction data for display
timing generation, brightness / contrast / chroma and density control.
•
Light valve driver circuits convert the input analog signals to the LCD (Liquid Crystal
Display) driver signals.

The only circuits that the interface signal lines for S-Video and Video In have are noise
filter circuits, therefore they output signals to the main board through the connector CN101.
Audio input signals from computer 1/2 (via Audio In 1/2) or from a video device (via Audio
In L/R) are input to the sound controller and amplified by the sound preamplifier. Then they
are output to the “Audio Out” interface or the built-in speaker through the sound controller
again.
The sound controller performs the audio-signal output selection based on the SCL/SDA
(serial clock /data) signals provided from the main board. The sound volume control uses 8
levels (mute ~ max.) based on the signals (SPAC 0/1) from the main board.

2.7 FR BOARD
The FR board is used for connecting the remote control receiver and a mouse or serial
interface of a host computer. The control has an 8-bit CPU and mouse / serial switching
circuit installed on the board.
CN100 (Mouse / COM1) and CN102 (Mouse / COM2) are multi-mouse connectors. If the
ELP communication kit is installed on the host computer and cables are connected to it,
you can control the computer with the remote control. The controller on the FR board
automatically determines the circuit operation mode (Mouse or Com) to apply the proper
circuit.
The optional remote control receiver can be connected to the remote control interface
(J100). The receiver provides the same functions as the standard receptor board
(FI / RI). Without the receiver, the remote control can be used within a limited area in the
front and rear. The receiver expands the range for the remote control.
Figure 2-15
The signals from the receptor board (FI/RI board) and the optional remote control receiver
are accepted by the remote (IC101), the infrared signals received from the remote control
are output under OR conditions to the main board through CN101 and the connector
board.
If a host computer with the ELP communication kit 2 option is connected to the interface,
the relay circuit is switched depending on each operation. This enables the switch data
transmission to the host computer and remote mouse operation by the remote control.
2-18
EPSON PowerLite 5000 Service Manual
The ELP communication kit 2 option also enables the remote control to draw lines and
patterns on the screen.
The relay circuit (IC111 or IC116C) is switched to be able to accept the mouse encoder
signal and the button signal. Then the signals based on “ Tracking +/- button” operation are
output to a host computer through the remote. The signals are transferred through the host
computer’s interface, and you can control (remote mouse controlling) the host computer
without its mouse.

presence of an external speaker and uses the built-in speakers if there is no external
speaker.
2.11 LIGHT GUIDE BLOCK
The light valve block eliminates ultraviolet rays, which are harmful to the light valves, and
makes the light intensity from the light source lamp uniform before dividing it into 3 light
outputs (R/G/B). Lenses and mirrors built into the block disperse the light. The illustrations
below show the outside of the light valve block and an internal diagram.

Lens Arrays A and B
After dispersion of the light from the light source lamp by lens arrays A and B, the
brightness is roughly uniform. A UV filter coats the surface of the multi-lens array to
eliminate ultraviolet rays. The light dispersed through the lens arrays A and B is further
dispersed through the PBS to make the light intensity uniform.
•
CDM
The CDM is a light filter that looks red in visual light. The CDM (A) filter transmits only
red light and reflects blue and green light from the light source.
•
GDM
The GDM is a light filter that looks blue in visual light. The GDM filter transmits only
blue light from the light source. Since the input light to the GDM is only blue and green
light from the CDM as described above, green light is reflected by the GDM and
provided to condenser lens G.
•
Condenser Lens L
Condenser lens L collects the light dispersed by the lens arrays A and B to prevent
reduction and provide light to mirror L in the next stage.

2.12 LAMP INNER HOUSING
The lamp inner housing consists of the DC drive light source lamp (150 W-350 V), the
power supply connector and the fuse board (FU board). The lamp mounted on the base of
the lower case is a user-replaceable item (Type: ELPLP03). The average brightness of the
lamp is 400 Im (ANSI). When the lamp is new, its brightness is approx. 450 Im (maximum).
After running about 2000 hours, the lamp’s brightness is reduced to almost half that of a
new one.
The fuse board (FU board) determines whether the lamp inner housing is installed, and
controls the lamp life (2000 hours). The power supply connector receives 350 VDC current
from the power supply unit, so its lead wire is connected to the lamp.
Power Supply Connector

EPSON PowerLite 5000 Service Manual
Light source lamp
The standard lamp life is 2000 hours. If you notice reduced lamp brightness, replace the
lamp inner housing even if you have used the projector for less than 2000 hours.
The total running time of the light source lamp is written in the EEPROM (IC603:
ST24W04FM6TR) on the main board. If the lamp is nearing or has reached the end of its
life, IC600 (M37732S4BFP) outputs signals to control the following:
When the total running time has reached 1900 hours (1900~2000), the orange and red
lamp indicators blink alternately. The controller (IC600) on the main board counts the total
running hours and writes the data in IC603. The lamp runs only 100 hours after the orange
and the red lamp indicators start to blink alternately, so you should replace the lamp as
soon as possible. (If the lamp indicators blink alternately when you turn the projector on,
the lamp life is no more than 100 hours. Therefore, the lamp life may be suddenly
terminated.)
When the total running time has reached 2000 hours, the fuse in the lamp inner housing is
blown by the LFUSE signal from IC600 and the lamp is turned off, then the cooling down
operation starts (the orange lamp indicator blinks). Afterward, the lamp will not run until
you replace it with a new one.

Figure 2-27
Fuse board (FU board)
This board has a 62 mA rated fuse. The terminal sections placed on the both ends of
this board touch the FC board installed on the base of the light guide unit. The cable of
the FC board is connected to connector CN250 on the driver board, so the signal from
the FC board is sent to the main board via the connector CN100. When the total running
time reaches 2000 hours, IC600 on the main board outputs an LFUSE signal, so the
2-28
EPSON PowerLite 5000 Service Manual
fuse on this board is connected to the ground through a resistance (88 Ω).
Consequently, the fuse is blown and the LLIFE signal is switched from HIGH to LOW.
When LLIFE becomes LOW, IC600 switches LPCTL to HIGH and shuts down the lamp
power (65 VDC) from the power supply unit. When the power is shut off, and LPST
(LPFAL) becomes HIGH, IC600 detects power off in the lamp and starts the cooling
down sequence.

2.13.1 Filter Cover Switch
This switch is installed in the lower case and locks with the tab of the filter cover. With the
filter cover open, the intake fan absorbs external air to cool down the light valve. This
allows dust get on the light valve and the prism, degrading the displayed image. The
switch is installed so you cannot turn on the projector when the filter cover is open.
Filter cover switch
Filter cover
Figure 2-28
The filter cover switch signal is connected to CN802 on the main board via CN202 on the
CN board. In main board circuit, IC100 generates the interrupt signal and outputs the
power shut off signal to CN800, so all regulating operations of the power supply unit are
stopped.
2-30
EPSON PowerLite 5000 Service Manual
2.13.2 Interlock Switch
This switch is installed on the side of the power supply unit and locks with a tab on the
lamp cover. If you turned on the projector with the lamp cover open, the light source lamp
(lamp inner housing) would run and generate high heat. To protect you from burns, the
interlock switch is installed on the AC power source line and the projector cannot be turned
on while the lamp cover is open.
Interlock switch
Figure 2-29
2.13.3 Safety Switch
This is the thermal switch for overheating protection installed on the lamp inner housing. If
an overheating condition is caused by contamination of the exhaust fan, the lamp
thermistor (described in 2.13.4) temporarily shuts off the supply of AC power to protect it
from overheating. The safety switch is installed to recognize overheating trouble in the
lamp thermistor.
Safety Switch
Figure 2-30
2-31
EPSON PowerLite 5000 Service Manual
The power supply unit cable is connected with a fastening tab to the safety switch. When
the temperature rises to a certain temperature, all regulating operations of the power
supply unit are stopped and power is shut off. Once this switch runs, you cannot start the
power until the temperature falls to a certain temperature. In this case, you must also
consider the lamp thermistor or the main board may be defective.
2.13.4 Lamp Thermistor
This is the temperature detection thermistor installed on the lamp outer housing (near the
safety switch). To protect the light source lamp from overheating, this thermistor shuts off
the power on the power supply unit if the temperature rises to a certain temperature (lower
than the safety switch’s level).
Lamp Thermistor
Figure 2-31
The lamp thermistor is connected to CN804 on the main board. If there is overheating,
IC600 generates an interrupt signal and shuts off power on the power supply unit via
CN800.
2.13.5 LV Thermistor
This is the temperature detection thermistor installed on top of the light valve. If cooling is
not sufficient because of intake fan failure (installed at the bottom of the light valve) or filter
contamination (installed at the top of the light valve), the power is shut off to protect the
light valves from overheating. The light valve (liquid crystal panel) has poor thermal
stability. The power shut off control is the same as the lamp thermistor’s, described in
section 2.13.4.

2.13.6 PBS Thermistor
This is the temperature detection thermistor installed on the side of the fan (attached to the
power supply unit). If the environment around the power supply unit overheats because of
a fan or circuit abnormality, this thermistor shuts off the power. The power shut off control
is the same as the lamp thermistor’s described in section 2.13.4.

3.1 Disassembly and Assembly Procedures
This section explains how to disassemble the projector. The reassembly procedure is the
exact reverse of the disassembly procedure.
3.1.1 Preparatory Procedures
1) Remove any ring, wrist watch, cuff buttons, or other metal accessories that are likely to
come into contact with the equipment.
2) Wear gloves.
3) Wear a wrist band and ground it. Place a ground mat under the unit.
4) Turn off the main unit and the host computer.
5) Unplug the power cord from the main unit and service outlet. (Even if the power is off,
back-up bias is regulated and supplied to the circuit board when the power cord is
connected to the service outlet.)
6) Disconnect the interface cable from the main unit.
7) Clean the air filter, interface, and case cover with a vacuum cleaner.

3.1.3 Limitations of Disassembly (Optical Engine Handling)
The disassembly of the mechanical section is detailed in section 3.2. The optical
engine is one replaceable part.

EPSON PowerLite 5000 Service Manual
These units are specified as the optical engine. (Treat as one replaceable part in field
maintenance.)
Optical head unit
À
Prism unit
Á
Light guide unit
Â
Projector lens unit
Ã
Driver board
Ä
Note: Do not disassemble the optical engine or replace any unit in the optical engine.
3.1.4 Mechanical Adjustments
Optical Head Unit
The polarization plates (R/G/B) are factory-aligned. Do not apply any mechanical
stress to the polarization plate, and do not loosen the screws. If the alignment is
modified, color divergence will occur, and the color images will not be clear.
Prism Unit
To synthesize the light output from each polarization plate (including R/G/B light
valves), the prism unit (concurrent with the polarization plate) is aligned in the factory.
If the alignment is modified, pixel divergence in R/G/B synthesizing and in the projector
lens unit causes out-of-focus images and non-uniform color.
Caution: Do not loosen the prism unit mounting screws.
Light Guide Unit
The components of the light guide unit are factory-aligned. If the alignment is modified,
clear images cannot be produced, because the brightness or chroma is not uniform on
the screen.
The lens array and mirrors are aligned in the factory to support the best display
performance of the light guide unit. If the alignment is modified or the location is
changed, the display screen may be distorted.
Caution: Do not disassemble the light guide unit. If you remove the upper guide
cover from the unit, the alignment of lenses or mirrors may be changed or
dust may stick to the unit. Since the projector requires precise adjustment, it
cannot be adjusted in the field.
3-2
EPSON PowerLite 5000 Service Manual
Projector Lens Unit
The projector lens unit is aligned (position and mounting torque) in the factory. If the
alignment is modified, pixel divergence will occur, creating unclear images.
Electrical Corrections: Driver Board
Some parts in the mechanical section of the optical system require adjustments as
mentioned above. In the control circuit (driver board), the output driver for the display
signal is slightly different from the output driver of other devices. The mechanical
section of the optical system (e.g., light valves) must be electrically corrected. To
obtain the best images, mechanical adjustments and electric corrections must be
made. For this reason, some correction values are written to flash ROM on the driver
board before shipping. Because this factory correction is necessary to match the
optical system with the electrical system, the driver board and the optical block
(consisting of the optical head/light guide unit) make one set.
At factory shipment, the following correction data is stored in the flash ROM on the
driver board for the specified optical engine.
Gamma adjustment data
Flicker adjustment data
Ghost contrast adjustment data
Sub contrast adjustment data
A special device and skilled engineer are necessary for writing correction values,
therefore the data cannot be adjusted in the field.
3.1.5 Cautions For Field Maintenance
Observe the following procedures when you repair the projector. Otherwise,
display quality is not guaranteed, and EPSON repair service will no longer be
available.
•
•
•
Do not disassemble the optical block or loosen any screws.
If either the optical block or the driver board needs replacement, replace them as
a set. Also, when you send them back for repair, send them back as a set
(optical engine).
Because the optical block and driver board make one set, you should never
change its combination (that is, use only the new driver board with the older
parts).
3-3
EPSON PowerLite 5000 Service Manual
3.1.6 Precautions
These precautions are for the individual assembly and disassembly procedures. Read
them carefully before starting an assembly or disassembly procedure. A set of general
precautions is given below.
As you disassemble the main unit, dust that has collected on the internal fans and air filters
is likely to migrate and contaminate light valves R, G, and B (the heart of the display
mechanism), deteriorating the display quality. To prevent this from occurring, check for
dust inside of the main unit and, if necessary, clean it with a vacuum cleaner before
reassembling. Light valves R, G, and B and circuit board assemblies are highly sensitive to
static electricity. When you remove an optical engine or circuit board, place it in an antistatic bag immediately.
When you perform the assembly or disassembly operations listed below, check the unit
and its surfaces for any dirt before reinstalling them. If the unit is dirty, clean it.
1. Removing the optical engine.
2. Removing the lamp inner housing.
3. Removing the air filter frame.
The speaker unit incorporates a permanent magnet. Keep it away from electromagnetic
media such as floppy disks and magnetic cards.
Handle the optical engine (projector lens and light guide unit) with care. They are highly
susceptible to vibration and shock.
Do not try to disassemble any part (e.g., power supply unit) that is not covered in this
manual.
