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 circuit 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

provided 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.

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 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(approx.8kV) 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.

PRODUCT SAFETY NOTICE

Product safety should be considered when a component replacement is made in any area of the projector. 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 must be made by exactly the same parts.

This projector uses a high-pressure lamp which must be handled carefully and properly. Improper handling may result in accidents, injury, or create a fire hazard.

● Lamp lifetime may differ from lamp to lamp and according to the environment of use. There is no

guarantee of the same lifetime for each lamp. Some lamps may fail or terminate their lifetime in a shorter period of time than other similar lamps.

● If the projector indicates that the lamp should be replaced, i.e., if the LAMP REPLACE INDICATOR lights

up, replace the lamp with a new one IMMEDIATELY after the projector has cooled down. ( Follow carefully the instructions in the LAMP REPLACEMENT section of owner's manual. ) Continuous use of the lamp with the LAMP REPLACE INDICATOR lighted may increase the risk of lamp explosion.

● A Lamp may explode as a result of vibration, shock or degradation as a result of hours of use as its

lifetime draws to an end. Risk of explosion may differ according to the environment or conditions in which the projector and lamp are being used.

IF A LAMP EXPLODES, THE FOLLOWING SAFETY PRECAUTIONS SHOULD BE TAKEN.

If a lamp explodes, disconnect the projector’s AC plug from the AC outlet immediately. Contact an authorized service station for a checkup of the unit and replacement of the lamp. Additionally, check carefully to ensure that there are no broken shards or pieces of glass around the projector or coming out from the cooling air circulation holes. Any broken shards found should be cleaned up carefully. No one should check the inside of the projector except those who are authorized trained technicians and who are familiar with projector service. Inappropriate attempts to service the unit by anyone, especially those who are not appropriately trained to do so, may result in an accident or injury caused by pieces of broken glass.

LAMP HANDLING PRECAUTIONS

The LAMP REPLACE indicator will light yellow when the total lamp used time (corresponding value) reaches 2,500 hours

- (✽). This is to indicate that lamp replacement is required. The total lamp used time is calculated by using the below expression;

Total lamp used time =

Teco + Tnormal x 1.25 - (✽) Teco : used time in the Eco mode Tnormal : used time in the Normal and Auto mode

You can check the lamp replacement counter following to below procedure.

1 Press and hold POWER ON-OFF button on the side

control of the projector or the remote control unit for more than 20 seconds.

MONITOR OUT

Page 63

NOTE : Temperature monitor operation

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 -1: -----------------------------------

■ To control the air-flow 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 judges data from sensors and controls the air flow of the cooling fans so the temperature inside the projector is maintained to normal temperature.

■ To shut down the projector urgent.

The CPU checks temperature of LCD panel periphery(PTH901) and inhalation air(IC5801). If each part temperature reaches to abnormal temperature, the CPU will turn off the projector, and will blink WARNING TEMP. indicator at intervals of 0.5 seconds. Cooling fans operate until temperature returns to normal. Indicator will stop blink, if temperature returns to normal.

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

■ Temperature check of lamps :

Temperature switches are arranged near the lamps. Temperature switches will operate, if temperature reaches 110 degrees. When temperature switches become open, they cut off 12V_PFC line, the power failure "PF_TH" signal become Low, and then the CPU will shut down the projector, and both of

READY and WARNING TEMP. indicators will start flashing.

NOTE : SENSORS OPERATION

■ The sensor's operation is as follows: IC886 : For FAN control PTH901 : Abnormal temperature detection IC2541 : Inside air temperature monitor IC5801 : Abnormal temperature detection

and for FAN control

WARNING TEMP. indicator (red) blink?

The projector is turned off when the temperature around the LCD panel reaches abnormal temperature. And a WARNING TEMP. indicator blinks.

- 63 -

The temperature switch is operated?

If the temperature around FET reaches 85 degrees, a PFC circuit will be shut down.

The temperature switch is operated?

When the temperature around a lamp driver reaches 85 degrees, the lamp ballast will be shut down and a lamp error signal changes from L to H.

Temperature sensors location can be seen on "protections"( page-7).

CPU : ---- Lamp monitor operation ----

■ The CPU performs an input check by the lamp monitor pin.

■ When the "H" signal continues 1 second or more continuously, the CPU judges the state to be abnormal.

■ When it has detected abnormal condition, the CPU turns off a projector compulsorily. And the CPU sets up the cooling time for 90 seconds.

■ The projector cannot be turned on during a cooling time.

NOTE :

■ Lamp Cover Switch

Make sure that the lamp cover is mounted correctly. If not or the lamp cover removed, the lamp does not light for safety. Check the boss of the lamp cover and the lamp cover switch (SW902).

SW902 -- open : Abnormality

■ Temperature Switches

When the internal temperature near the lamps reaches near 110ºC, the temperature switches open and 12V_PFC is not supplied to PFC-Unit.

SW903 - SW906 -- open : Abnormality

■ READY (green) LED indicates lamp monitor operation

LED off: Lamp is being cooled. LED on: Lamp is being lit or already cooled down.

NOTE :

■ At first, the high-voltage pulse (about 8KVp-p) is generated between the lamp electrodes to generate glow discharge. Then dielectric breakdown occurs, finally glow discharge comes to arc discharge.

■ After projector turned on, 30 seconds are required until the light output

stabilizes.

■ After the projector is turned off, the cooling fans operate for 90 seconds to

cool down the lamp and reduce gas pressure inside the lamp.

■ The Lamp Driving Circuit ( example Lamp_3 )

■ When the tempera-

ture around a lamp driver reaches 85 degrees, unit lamp ballast will be shut down and a lamp monitor signal changes from L to H .

■ When the output voltage reaches abnormal voltage (exceeds AC 130V), unit lamp ballast will be shut down and a lamp monitor signal changes from L to H.
