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. Do not disconnect the AC cord or turn off the AC breaker during the fans are operating.

  • Turn off the power after the POWER indicator lights red.

3. 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.

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

INF-29

[Attention] •  When replacing the consumable parts, please make sure that the power cable is disconnected from the outlet.

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".

  * Download the service software from Projector service web site.

2.  When replacing the [A] or [DG] printed circuit board, write the latest version of main firmware again to make consistency

 

between Main and FPGA firmware.

[Note] 

•  If you cannot transfer the data by using the software, remove the [IC3711/IC3712] on the original board and mount it on the

new board.

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