5. 2. 3. Repair
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.
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.
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 ormal on a self check screen.
4. Do handling and safekeeping carefully because the user setup information remains in the projector.

4. Do handling and safekeeping carefully because the user setup information remains in the projector.
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 soft. Then transfer this data to the new A-P.C.Board.
For more information refer to the SECTION 3 "Adjustment".
2. If you cannot transfer the data that uses the service software, remove [ IC3711 ] from the original board and mount
them on the new board.
3. When A-P.C.Board is replaced, the MAC address of wired LAN will be changed. Explain it to the customers in advance.
