This projector provides a function to get the error information of the projector by using the RS-232C serial port for the 
power failure diagnosis.
The further error information of the power failure and fan failure can be found out by using this function.

 Connect a RS-232C serial 

straight

 cable to CONTROL PORT on the projector and serial port on the PC.

  Launch a communication software "Hyper terminal" provided with PC and setup the communication condition as 

follows;

 

 

Baud rate 

: 9600 / 19200 bps

 

Parity check 

: none

 

Stop bit 

: 1

 

Flow control 

: none

 

Data bit 

: 8

  Turn  on  the  projector.  Check  that  the  LED  shows  a 

power failure. (All the LEDs are blinking)

  Type  a  diagnosis  command  of  the  power  failure  “CR 

ALLPFAIL” and press a "ENTER" key within 1 second 
on the command window of the software.

The  error  information  will  be  listed  on  the  window  as 
the right.
Check  the  status  column.  If  “NG”  is  listed,  the  power 
failure occurs on its signal line (Power Line Name). In 
case of the right table, this error information means that 
the power failure occurs on the 3.3V power supply on 
the GAMMA (Digital Gamma) circuit on the main board 
(GAMMA, 3.3V). Check if the parts connected to 3.3V 
power supply line on the Gamma circuit are defective.

Also the error information may be listed multiple as the 
below;
In  the  above  case,  2  kinds  of  causes  are  considered. 
One is the power failure occurs on the multiple places 
at the same time, other is a power failure affects mul-
tiple power supply lines even if the failure occurs on the 
single place.

In  the  first  case,  Check  if  the  parts  connected  to  the
multiple  power  supply  lines  are  defective.  In  the  later 
case,  determine  a  failure  point  referring  to  the  power 

supply  flow  chart  on  previous  page.  Basically,  if  the
power failure occurs on the upper side of power supply, 
the power failure is also detected on lower side of power 
supply frequently. If the failure occurs on the lower side of power supply, it is lightly affected to the upper side of the 
power supply. In the above case, because the failure occurs on the S3.3V power supply on the main board (MAIN, 
S3.3V), the failure is also detected on the 1.2V power supply on the main board (SWFPGA, 1.2V).

* See "Power Failure Detection System" for further description of the Error Information.

The serial connector which is on the connector panel of the projector conforms to the RS-232C interface 

specification, so that the projector can be controlled by a personal computer which is connected to this connector.
