1. Since very strong light is leakage from the surroundings of optical block, when checking or adjusting the projector with top
cabinet removal, ware the UV protection glasses to protect the UV light.
2. Before repairing, make sure to turn off the main power and disconnect the power plug 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. Please take care in static electricity, use an antistatic wrist strap or 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.
5. 2. 3. Interlock detection
The lamp cover switch detects whether the lamp cover is mounted securely.
When the lamp cover is mounted securely, the interlock switch (K8S) on the [A]-P.C.Board turns on.
5. 2. 4. Replacement of A-P.C. board
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 software. Then transfer this data to the new [A]-P.C.Board.
For more information refer to the SECTION 3 "Adjustment".

5. 3. Replacement of consumable parts
[Attention] • When replacing the consumable parts, please make sure that the power cable is disconnected from the outlet.
5. 3. 1. When to replace the lamp unit
The lamp unit is a consumable component. Since its brightness gradually decreases over time, it is necessary to replace the
lamp unit regularly. The estimated duration before replacement is 5 000 hours, but the lamp may go off before reaching to
5000 hours, depending on the characteristics of the individual lamp, usage conditions, and the installation environment. It is
recommended that the Replacement Lamp Unit be prepared earlier.

Over 4 800 hours
The message is displayed for 30 seconds. Pressing
any button on the control panel or remote control
within 30 seconds will clear the message.
The indicator lights in red even during the
standby mode.
Over 5 000 hours The message remains displayed until you press any
button.
If you continue to use the lamp unit after 5 000 hours has elapsed, the lamp turns off automatically after approximately 10
minutes, as it may cause malfunction of the projector.
Note
• To predict when to replace the lamp, check the lamp runtime displayed at [STATUS] - [RUNTIME] in [PROJECTOR SETUP].
• 5 000 hours is only the target for replacement and not the warranty time.
5. 3. 2. Calculation formula of lamp runtime
The lamp runtime that is displayed in the [STATUS] is real time.
The following conversion is required to calculate the rough estimate for lamp replacement.
Formula for lamp replacement time (rough estimate)
= “Lamp runtime of [NORMAL]” + “Lamp runtime of [ECO]” × 5/7
5.2.5. Optical block type check
There are 2 types of optical block, named R-type and L-type.
When replacing the optical block, check the printed marker on the flat cable of the G-LCD panel and use the same type of the
optical block. If not used the same type, you will find the color shading or wrong white balance picture on the screen.
