SERVICE PERSONNEL WARNING

Eye damage may result from directly viewing the

light produced by the Lamp used in this equipment.

Always turn off Lamp before opening cover. The

Ultraviolet radiation eye protection is required during

this servicing.

Never turn the power on without the lamp to avoid

electric-shock or damage of the devices since the

stabilizer generates high voltages (20~25kV) 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.

WARNING:

The chassis of this projector is isolated (COLD) from

AC line by using the converter transformer. Primary

side of the converter and lamp power supply unit cir-

cuit is connected to the AC line and it is hot, which

hot circuit is identified with the line ( ) in the

schematic diagram. For continued product safety and

protection of personnel injury, servicing should be

made with qualified personnel.

The following precautions must be observed.

SAFETY PRECAUTIONS

1: An isolation transformer should be connected in the

power line between the projector and the AC line

before any service is performed on the projector.

2: Comply with all caution and safety-related notes pro-

vided on the cabinet back, cabinet bottom, inside the

cabinet or on the chassis.

3: When replacing a chassis in the cabinet, always be

certain that all the protective devices are installed

properly, such as, control knobs, adjustment covers

or shields, barriers, etc.

DO NOT OPERATE THIS PROJECTOR WITHOUT

THE PROTECTIVE SHIELD IN POSITION AND

PROPERLY SECURED.

4: Before replacing the cabinet cover, thoroughly

inspect the inside of the cabinet to see that no stray

parts or tools have been left inside.

Before returning any projector to the customer, the

service personnel must be sure it is completely safe

to operate without danger of electric shock.

PRODUCT SAFETY NOTICE

Product safety should be considered when a compo-

nent replacement is made in any area of the projec-

tor. Components indicated by mark in the parts

list and the schematic diagram designate compo-

nents in which safety can be of special significance.

It is, therefore, particularly recommended that the

replacement of the parts must be made by exactly

the same parts.

DO NOT ATTEMPT TO SERVICING THE

REMOTE CONTROL UNIT.

Laser Beam may be leaked out when in disassem-

ble the Unit. As the Laser Beam used in this

Remote control unit is harmful to the eyes.

Safety Instructions

This projector is equipped with the following protections

to operate in safety.

❏ Fuse for circuit protection

Protections

The fuse is located in the rear inside a projector. (Refer to figure.) When

either the LAMP indicator or the READY indicator is not illuminated,

fuse may be opened. Check the fuse as following steps.

1. Remove the Cabinet-top following to “Mechanical Disassemblies”.

2. Remove the fuse from fuse holder.

3. Check the resistance of fuse using a tester.

To install the fuse, take reversed step in the above.

It should be used the specified fuse as follows;

LAMP COVER

■ The Lamp circuit (the lamp and the electrode of the lamp socket)of this

projector is not insulated from AC line, and it is "HOT." Therefore,

when replacing lamp assembly, an electric shock may be received.

However, the interlock switch (SW902) is designed so that it may protect

from the accident.

■ This switch(SW902) insulates a lamp circuit from AC line, when a lamp

cover is removed. (The lamp circuit changes to "COLD.")

----- The temperature monitor -1: -----

■To control the driving power of the cooling fans.

The CPU checks the temperature and atmospheric pressure

inside a projector. It checks a temperature using temperature

sensor-IC5801 and it checks an atmospheric pressure using

pressure sensor-IC886.

The CPU controls the driving power of the cooling fans so the

temperature inside the projector is maintained to normal tem-

perature.

■To shut down the projector.

The CPU checks temperature of Red-LCD panel periphery

(IC2541) and inhalation air(IC5801). If each part temperature

reaches to abnormal temperature(IC2541 ; 47degrees /

IC5801 ; 42degrees), the CPU will turn off a projector, and

will blink TEMPERATURE WARNING indicator at intervals

of 0.6 seconds. Cooling fans operate until temperature returns

to normal. Indicator will stop blink, if temperature returns to

normal.

Y/V

The temperature monitor system is provided to prevents damage of optical components (the LCD panel and polarization film etc.)

inside a projector from overheat. Two protection systems are provided.

Each system operation as follows ;

--- The temperature monitor -2 : ---

(Temperature check of lamps. )

Temperature switches (SW 903~904) are arranged near the

two lamps. Temperature switches will operate, if temperature

reaches 90~100 degrees.

SW904 (Lamp-1)----- It operates at 90 degrees.

SW903 (Lamp-2)----- It operates at 100 degrees.

When temperature switches have operated, lamp ballast units

will be shut down, then a projector will be turned off.

Note.

CPU does not check operation of temperature switches.

Therefore, when temperature switches have operated and a

projector has shut down, TEMPERATURE-WARNING

indicator does not blink.
