SAFETY INSTRUCTIONS

1. MAINTAINING OPERATOR SAFETY

1. PREVENTING ELECTRIC SHOCKS

•Turn off the power switch and disconnect the power cord from the AC outlet before car-

rying out any disassembly and assembly work on this projector.

•If power needs to be supplied to the projector while the cover is removed (such as when

making adjustments), take off any metallic objects such as wristwatches, shirt cuff but-

tons, rings and tie pins which may pose the danger of coming into contact with the pro-

jector.

2. PREVENTING INJURY

•Do not touch the lamp assy and the area around it with bare hands immediately after

turning the power off, or even after cool-down period is completed since the lamp and

the area around it may still remain hot.

•When removing the cover in order to carry out adjustments while power is being sup-

plied to the projector, be careful not to touch the fans (intake and exhaust).

•Always wear gloves when disassembling and reassembling the projector in order to

avoid injury from metallic parts with sharp edges.

•Do not look directly into the projector's lens while power is being supplied to the projec-

tor, otherwise your eyes may be injured.

3. PREVENTING ACCIDENTS

•Place the projector on a stable, level surface when carrying out any repair or adjustment

work, to prevent the projector and its components from slipping and falling down. Fur-

thermore, do not place any tools or projector components on top of or underneath the

projector.

•Avoid working on the projector in places where other people might receive injuries from

touching the projector while it is in a state of disassembly. Furthermore, do not leave the

projector unattended in the workplace at such times.

•When turning on the projector's power, always use the accessory power cord to connect

the projector to the power supply, and always make sure that the power supply is prop-

erly grounded.

2. MAINTAINING THE PROJECTOR IN GOOD CONDITION

1. PREVENTING STATIC ELECTRICAL DAMAGE

•When disassembling and assembling the projector, always use a grounding strap and a

grounding mat. Furthermore, when replacing electrical circuit components (such as cir-

cuit boards and optical engine), bring the static-proof bag containing the new parts into

contact with a metallic section of the projector before taking out the component from the

static-proof bag.

2. USE OF GENUINE PARTS

•When replacing the structural components inside the projector (including the lamp assy),

use only replacement parts supplied by EPSON and listed in the projector's Parts List.

•Use the accessory power cord and interface cable provided with the projector.

3. SAFETY TESTING

The following tests should be carried out on repair parts used in the LCP.

Note:These are simplified tests that can be carried out at a repair centre that is not

equipped with full safety testing equipment.

Test items

1). Insulation resistance test

2). Ground continuity check

3). Illumination check

Testing procedure

Carry out testing in the order given below.

Testing methods

1). Insulation resistance test

•Testing apparatus: Insulation ohmmeter (Rating: 500 V/100 MΩ)

•Insulation ohmmeter settings

Check Item Tool Standard

Insulation resistance check Insulation ohmmeter Insulation resistance

should be 10 MΩor

more.

Repair EndInsulation resistance test Ground continuity check

Safety inspections

Illumination check

Projector AC inlet

Computer IN connector

(1) (2)

1. Set the range selection switch to 500 V.

2. Connect the black lead wire to the ground terminal.

3. Connect the red lead wire to the line terminal.

4. Connect the black lead wire (crocodile clip) to c in

order to measure the insulation resistance (1) (between

a and c) in the diagram below.

5. Next, insert the probe of the red lead wire into a.

6. Set the measure switch to LOCK, and then measure the

insulation resistance after 1 minute.

7. Check that the insulation resistance after 1 minute is

10 MΩor more.

8. Next, measure the insulation resistance at (2) (between

b and c) in the diagram below in the same way as for

(1).

9. Check that the insulation resistance at (2) after 1 minute

is 10 MΩor more.

2). Ground continuity check

•Testing apparatus: Multimeter (with sensitivity down to 0.1 Ω)

•Multimeter settings

3). Illumination check

•Test conditions: Input a PC or video signal to the projector and check the illumina-

tion for about 5 minutes.

•Evaluation: Projector should operate normally with no smoke or fire.

Check Item Tool Standard

Ground continuity check Multimeter Should be no resistance

(0.5 Ωor less)

1. Turn on the power switch.

2. Set the range selection switch to Ω.

3. Connect the black lead wire to the COM terminal.

4. Connect the red lead wire to the V/Ω/Hz terminal.

5. Check that the resistance at (1) in the diagram below is

0.5 Ωor less.

Other

•Check that the connectors at both ends of the power cord are not dirty or bent, and clean

them if they are dirty. Furthermore, if there is any noticeable discoloration on the power

cord, it should be replaced.

•When connecting the connector cables and interface cables inside the projector, make

sure that the cable connectors are pushed on as far as they will go.

•To prevent problems caused by dirt getting into the optical system, always disassemble

and assemble the projector in an area which is free from floating dust.

•When disconnecting the FPC cable from the CN502 of the MA board assembly, release

the connector locks. To release the connector lock, push up both ends of the connector

simultaneously with tweezers.

•When disconnecting the three FPC cables for the light valves from their connectors,

release the connector locks first.
