SECTION 1  SERVICE  INFORMATION

< RZ670/RW630 >

1. LD(Laser) unit that is mounted on the inside of the light source unit is classified in Class 4 of the safety standards.

・

Laser light is very danger, can damage the human eye and skin.

・

Please do not perform energization in the state where the lighting block was disassembled.

2. Depending on the operating environment temperature, the luminance of the light source will decrease.

・ When using the projector at elevations lower than 2 700 m (8 858') above sea level, and the operating environment

temperature becomes 35 °C (95 °F) or higher, the luminance of the light source may decrease.

・ When using the projector at elevations between 2 700 m (8 858') and 4 200 m (13 780'), and the operating

environment temperature becomes 25 °C (77 °F) or higher, the luminance of the light source may decrease.

・ The higher the temperature becomes, the more the luminance of the light source decreases.

3. The luminance of the light source (LD units) will decrease by duration of usage.

・ The time until when the luminance of the light source decreases by half differs depending on the setting of the

[PROJECTOR SETUP] menu → [OPERATION SETTING] → [OPERATING MODE].

・ The estimated time until when the luminance of the light source decreases by half is as follows.

・ The foregoing time is a rough estimate when the projector is used without changing the settings of

[OPERATING MODE] and [CONSTANT MODE], and will vary depending on ndividual differences and

usage conditions.

4. Static electricity or electrical surges will reduce and degrade the reliability of LD unit.

・ When working with the LD unit take countermeasures to avoid the generation of static electricity, Use or wear

appropriate work clothes, gloves, shoes, grounded wrist straps and other tools to avoid static electricity.

1. The DMD chips are precision-made. Note that in rare cases, pixels of high precision could be missing or always lit.

・

Note that such phenomena do not indicate malfunction.

2. Directing a high-power laser beam onto the projection lens surface can damage the DMD chips.

1. The lithium battery is used for the internal clock in the A-P.C. board. So when it consumed it must be replaced.

2. After replacing the lithium battery, set the [Date and Time] on the sub-menu which in main menu [projector setup].

To revert to the factory default password (AAAA), perform the following operations while the screen asking for a control

device password input is displayed.

1) Press the [AUTO SETUP] button on the remote control for at least two seconds.

2) Press ▼ for at least two seconds.

Initial password　: Press [

SECTION 1  SERVICE  INFORMATION

< RZ670/RW630 >

The basic service policy is shown below.

・ PC-P.C.Board (Specified components are replaced)

・ D-P.C.Board

・ DMD block (Specified components are replaced)

・ LD unit

・ Lens unit

・ Rod ASSY

1. Hexalobe (TORX type) driver [2.72 mm]

・ VESSEL T10H or comparable product
・ Part No. : TZSH07035

2. Hexalobe (TORX type) driver [3.94 mm]

・ VESSEL T20H or comparable product
・ Part No. : TZSH07042

3. Hex wrench  [2.5 mm]

・ Use the Hex wrench on the commercially available.

4. Laser safety glass

・ Please wear glasses for safety when checking with the cover removed.
・ Type : Full absorption, Adaptation laser : Ar, Wavelength : 448 - 462nm
・ Part No. : TZSH07038  (or comparable product)

1. Energization check and adjustment, after assembling the lighting block completely.

・ Before turning on the power, please make sure that the lighting block is completely assembled.
・ The service engineer who works on this model and also other people who are in the same room need

to wear the laser safety glasses for avoiding the laser irradiation just in case.

2. Before repair, make sure to turn off the main power and unplug the power cord from the power outlet.

* When replacing the print board, the internal electrical parts can be broken by the static electricity of clothes or

human body. Be careful of static electricity and wear the anti-static electricity gloves.

3. After repairing, please check the gradation (10step or the gray scale) test pattern or moving image.

Also, please check that it is normal on a self check screen.

4. Do handling and safekeeping carefully because the user setup information remains in the projector.

1. When the replacement of A-P.C.Board (assembly) is needed, back up the memory information such as adjustment data 

from the old board to PC with the service soft. Then transfer this data to the new A-P.C.Board.

For more information refer to the SECTION 3 "Adjustment".

* If you cannot transfer the data that uses the service software, remove [ IC3711 ] from the original board and mount 

them on the new board.

2. When replacing the printed circuit board, update each firmware to the latest version.

3. When A-P.C.Board is replaced, the MAC address of wired LAN will be changed. Explain it to the customers in advance.

1. Make sure that all the connectors are connected completely.
2. Especially, pay attention for the connection of the connectors on the LD unit. If the projector is turned on in the state of 

the connectors disconnected, the LD error will occur and be memorized in the memory.

The error information will not be reset even if the connector is re-connected correctly.

In this case, you need to take the runtime reset of its LD unit by the LD reset software.

(The LD error information will also be reset.)
