■ Safety Instructions

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 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.

Circuit Protections

● Warning temperature and power failure protection

The TEMP WARNING indicator flashes red and the projector will automatically turn off when the internal temperature of the projector exceeds the normal temperature or when stopping cooling fans or when the internal power supply lines are failed.

Check the following possible causes and wait until stopping the TEMP WARNING indicator flashing.

Possible causes

- Air filter is clogged with dust particles. Remove dust from the air filter 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)

If the TEMP WARNING indicator still continues to flash, there may be defects on cooling fans or power supply circuits. Please check fan operation and power supply lines referring to the “Power Supply Lines Chart”.

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 filter, 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 an air filter

by pulling the latches of them upward.

3. Clean the air filter with brush or wash out the dust and

particles.

4. Replace the air filter properly. Make sure that the air fil-

ter is fully inserted.

CAUTION:

Do not operate the projector with the air filter removed. The dust is stuck on the LCD panel and the mirror, and it may spoil the fine picture image. Do not put the small parts into the air intake vents. It may result in the malfunction of the projector. The air filter is small parts. Take care that children don’t eat or swallow it.

RECOMMENDATION

We recommend to avoid dusty, smoky place for operating the projector. Using in dusty place may cause the picture of poor quality. When using under the dusty or smoky conditions, dust may accumulate on the LCD panel and lens inside it, and may resultantly be projected on the screen together with the picture. When the above symptoms are noticed, please clean up the LCD panel and lens following to the “Cleaning Method”.

● Service Adjustment Menu Operation

IC1801 on the main board stores the data for the service adjustments, and should not be replaced except for the case of defective device. If replaced, it should be performed the re-adjustments following to the “Electrical Adjustments”. The data of lamp replacement monitor timer is stored in the IC1801. Please note that the lamp replace counter is reset when the memory IC (IC1801) is replaced. (Lamp replace counter can not be set to the previous value.)

● Caution to memory IC replacement

When IC1801 is replaced with new one, the CPU writes down the default data of the service adjustments to the replaced IC, refer to the service adjustment table. As these data are not the same data as factory shipped data, it should be required to perform the re-

adjustments following to the “Electrical Adjustments”. Please note that the lamp replace counter is reset.

● Caution of Main Board replacement (in the case IC1801 is not defective)

When the main board is replaced, IC1801 should be replaced with the one on previous main board. After replacement, it should be required to perform the readjustments following to the “Electrical Adjustments”. In this case, the lamp replace counter can be kept the v

alue as before.

■ Troubleshooting

No Power

The possible causes of No Power are listed below. Please check following and refer to power supply and protection circuits diagram in the figure opposite.

1. Stop the operation of power supply circuit due to detection of abnormality

.

- Detected the abnormality on the secondary power supply

lines.

Power failure detection diodes detect an abnormal voltage on the power supply. Check the shortage of secondary circuits, ICs, condensers, etc.

- Detected the operation stop of cooling fans.

Power failure detection diodes detect the fan operation stop. Check Fans FN901, FN902, FN903, FN904, FN905 and FN906 Check fan's power supply lines and detection diodes and transistors D69A, D69B, D69C and Q69A

- Detected the abnormal temperature rise inside the projec-

tor.

Temperature sensor ICs detect abnormal temperature. Check peripheral circuits and sensor ICs IC4881 and IC2881. Thermal switch (TSW611) detects abnormal temperature. Check peripheral circuits and TSW611.

TSW611.................... open in normal

TSW611 shorts when the peripheral temperature is over 90°C. Thermal switch (SW902) detects abnormal temperature. Check peripheral circuits and SW902.

SW902...................... short in normal

SW902 opens when peripheral temperature is over 100°C.

- Detected the abnormality on the lamp ballast unit. The lamp ballast unit outputs error signal (LAMP_ERR) to pin 47 of IC801.

LAMP_ERR .............. High in abnormal

- Detected the over load/over voltage on power supply circuit. Feedback circuits detect over load or over voltages. Check PC641, PC642 and peripheral circuits.

- Operated the mechanical protect on the Interlock switch

(SW904). Check lamp cover fixed correctly.

- Fuse (F601) open.

2. Abnormality occurs on drive signals for power

or lamp circuit.

- Abnormality on power starter signals (POWER, 5V_SW). POWER signal is output from pin 1 of IC801 and sent to pin 17 of IC1881, and output from pin 3 by the name of 5V_SW signal. 5V_SW signal drives 15.5V and 9VMCI power supply circuits on the power board.

POWER/5V_SW ............ High in power on

Check POWER and 5V_SW signals, 9V regulator circuit Q65A, Q65B, Q65C, IC65A and peripheral circuit, 15.5V switch circuit Q661, Q662 and peripheral circuit on the Power Board.

- Abnormality on lamp ballast drive signal (BALLAST_AC). BALLAST_AC signal is output from pin 39 of IC801 and sent to pin 11 of IC1881, and output from pin 9 by the name of BALLAST_AC1 signal. BALLAST_SW1 signal drives the lamp ballast unit. Check BALLAST_AC and BALLAST_AC1 signals and lamp ballast unit.

- Abnormality on fan drive signal (FAN DRIVE). FAN DRIVE signal is output from pin 41 of IC801 and sent to pin 15 of IC1881, and output from pin 5 by the name of FAN DRIVE1 signal. FAN DRIVE1 signal drives fan supply voltages (12V/12V1) on the power board.

FAN DRIVE/

FAN DRIVE1 .............. High in power on

Check FAN DRIVE/FAN DRIVE1 signals, 12V regulator circuits IC681, Q681, Q682, Q66A, IC671, Q671, Q672 and peripheral circuits.

- Abnormality on power drive signal (LAMP_BST_SW). LAMP_BST_SW signal is output from pin 82 of IC801 and sent to pin 2 of IC1871, and output from pin 18 by the name of LAMP_BST_SW1 signal. LAMP_BST_SW1 signal drives the power factor control IC on the P.F. board through the Power board.

LAMP_BST_SW/

LAMP_BST_SW1 ............ High in power on

Check LAMP_BST_SW and LAMP_BST_SW1 signal, photo-coupler PC643, transistors Q651, Q641 and peripheral circuits.

3. Abnormality occurs on the power circuit.

- Abnormality on power primary circuit Check Line filters, L601, L602, D614, L611, IC631, D632, etc.

- Abnormality on power secondary circuit Check D651, D652, D653, IC651, etc.

■ Cleaning

Cleaning with air spray

1. Remove the cabinet top following to “Mechanical Disassemblies”.

2. Clean up the LCD panel and polarizing plate by using the air spray from the cabinet top opening.

Caution:

Use a commercial (inert gas) air spray designed for cleaning camera and computer equipment. Use a resinbased nozzle only. Be vary careful not to damage optical parts with the nozzle tip. Never use any kind of cleanser on the unit. Also, never use abrasive materials on the unit as this may cause irreparable damage.

After long periods of use, dust and other particles will accumulate on the LCD panel, prism, mirror, polarized glass, lens, etc., causing the picture to darken or color to blur. If this occurs, clean the inside of optical unit.

Remove dust and other particles using air spray. If dirt cannot be removed by air spray, disassemble and clean the optical unit.

Disassembly Cleaning

Disassembly cleaning method should only be performed when the unit is considerable dirty and cannot be sufficiently cleaned by air spraying alone.

Be sure to readjust the optical system after performing disassembly cleaning.

1. Remove the cabinet top and main units following to “Mechanical Disassemblies”.

2. Remove the optical base top following to “Optical Unit Disassemblies”. If the LCD panel needs cleaning, remove the LCD panel unit following to “LCD panel replacement”.

3. Clean the optical parts with a soft cloth. Clean extremely dirty areas using a cloth moistened with alcohol.

Caution:

The surface of the optical components consists of multiple dielectric layers with varying degrees of refraction. Never use organic solvents (thinner, etc.) or any kind of cleanser on these components. Since the LCD panel is equipped with an electronic circuit, never use any liquids (water, etc.) to clean the unit. Use of liquid may cause the unit to malfunction.
