10. PN-465 MAIN PWB/PANEL/PARTS REPLACEMENT PROCEDURES
10-1. OUTLINE
In the PN-465 series, the following information as well as user setting
information are saved to the EEPROM (IC402, 404) of the main unit.
(3 and 4 are information linked with the panel.)
1 MODEL NAME
2 SERIAL NUMBER
3 USAGE TIME
4 WHITE BALANCE SETTING VALUE
5 CALIBRATION SETTING VALUE
6 TEMPERATURE MONITOR SETTING INFORMATION
Therefore, when the PWB, the panel, IC402, or IC404 is replaced, ini-
tialization and setting must be performed according to necessity.
In addition, after completion of the work, perform ALL RESET.
10-2. INFORMATION ITEMS
1 MODEL NAME
The model name must be set depending on the destination.
For setting procedures, refer to “8. MODEL NAME SETTING PRO-
CEDURES”.
2 SERIAL NUMBER
The machine has its own serial number which is described on the
nameplate at the back of the machine.
For setting procedures, refer to “6. SERIAL NUMBER WRITING
PROCEDURES”.
3 USAGE TIME
This information is linked with the panel. When replacing the PWB,
read the information before replacement, and write it to the new
PWB after replacement.
For setting procedures, refer to “7. USAGE TIME SETTING PRO-
CEDURES”.
4 WHITE BALANCE SETTING VALUE
This information is linked with the panel. When replacing the PWB,
read the information before replacement, and write it to the new
PWB after replacement.
Execute resetting when the panel is replaced.
For setting procedures, refer to “3-5. WHITE BALANCE SETTING
PROCEDURES”.
5 CALIBRATION SETTING VALUE
Since a service part PWB has been adjusted, there is no need to
set when replacing the PWB.
Setting may be required depending on the changed part.
For setting procedures, refer to “3-2. CALIBRATION”.
6 TEMPERATURE MONITOR SETTING INFORMATION
This is the setting information related to temperature watch.
Execute resetting when replacing the PWB or the panel.
For setting procedures, refer to “9.TEMPERATURE MONITOR
SETTING PROCEDURES”.
10-3. PWB REPLACEMENT PROCEDURES
1) Read the following information from the monitor before replacement
of the PWB.
1 USAGE TIME
2 WHITE BALANCE VALUE
*If the machine does not operate before replacement and reading
cannot be made, this procedure is not required.
2) Replace the PWB and execute FACTORY RESET.
(Refer to “3-3. FACTORY RESET”.)
3) Write data into EDID.
(Refer to “5. EDID WRITING PROCEDURES”.)
4) If necessary, update the firmware.
(Refer to “4. FIRMWARE UPDATE PROCEDURES”.)
5) Set the MODEL TYPE depending on the destination.
(Refer to “MODEL TYPE” in “3. SERVICE MENU”.)
6) Write the information read in the above step 1).
*When reading cannot be made in the step 1):
• Set “0” to USAGE TIME and perform initialization.
• Reset the WHITE BALANCE set values.
7) Write the serial number.
(Refer to “6. SERIAL NUMBER WRITING PROCEDURES”.)
8) Reset the temperature watch setting information.
(Refer to “9. TEMPERATURE MONITOR SETTING PROCE-
DURES”.)
10-4. PANEL REPLACEMENT PROCEDURES
1) Set “0” to USAGE TIME and perform initialization.
2) Reset the WHITE BALANCE set values.
3) Reset the temperature watch setting information.
(Refer to “9. TEMPERATURE MONITOR SETTING PROCE-
DURES”.)
10-5. MAJOR PARTS REPLACEMENT PROCEDURES
When any one of major parts is replaced, perform the FACTORY
RESET and set as shown in the table below.
