PN-K321/K322B IMPORTANT INFORMATION FOR SERVICING THE DISPLAY 3-1
CHAPTER 3. IMPORTANT INFORMATION FOR SERVICING THE DISPLAY
1. I/F PWB, LCD MODULE, PARTS REPLACEMENT PROCEDURES
The following information as well as user setting information are saved to the EEPROM (IC1101) controlled by main firmware.
<INFORMATION STORED IN THE EEPROM’S (IC1101) CONTROLLED BY THE MAIN FIRMWARE.>
・
MODEL NAME
・
SERIAL NUMBER
・
USAGE TIME*1
・
WHITE BALANCE SETTING VALUE*１
・
GAMMA SETTING VALUE
・
SYSTEM LOG
*1 This information is linked with the LCD module.
Therefore, when the I/F PWB, the LCD module or EEPROM (IC1101) is replaced, initialization and setting must be performed according to
necessity. In addition, after completion of the work, perform “ALL RESET”.
(CAUTION)
・
IC1101 cannot be replaced by the service engineer because the MAC address is written in it. IC1101 is not the service parts.
1-1. INFORMATION ITEMS
MODEL NAME
In some cases, the model name to be set may be different.
→Refer to “5-1. MODEL NAME SETTING FUNCTION”
→Refer to “13. MODEL NAME SETTING PROCEDURES
SERIAL NUMBER
The machine has its own serial number which is described on the nameplate at the back of the machine.
→Refer to “5-2.SERIAL NUMBER SETTING FUNCTION”
→Refer to “11.SERIAL NUMBER WRITING PROCEDURES
USAGE TIME
This information is linked with the LCD module. When replacing the I/F PWB, read the information before
replacement, and write it to the new I/F PWB after replacement. It is necessary to initialize this setting when
the LCD module is replaced.
→Refer to “5-3. USAGE TIME SETTING FUNCTION
→Refer to “12. USAGE TIME SETTING PROCEDURE”
WHITE BALANCE
SETTING VALUE
This information is linked with the LCD module. When replacing the I/F PWB, read the information before
replacement, and write it to the new I/F PWB after replacement. Execute resetting when the LCD module is
replaced.
→Refer to “8. WHITE BALANCE TOOL OPARATING PROCEDURE”
GAMMA
SETTING VALUE
This value is linked with the LCD module. When replacing the I/F PWB, read this value before replacement
and write it into the I/F PWB after replacement. When replacing the LCD module, reset this value.
→Refer to “10. GAMMA SETTING PROCEDURESWITH THE OSD”
SYSTEM LOG
INFORMATION
This information is included in user operation and system information.
→Refer to “ 14.OPERATING MANUAL OF THE LOG TOOL“

→ Refer to "13. MODEL NAME SETTING PROCEDURES”
6) Write the information read in the above step 1).
When the reading cannot be executed, perform the following operation.
--- Set “0” to USAGE TIME and perform initialization.
--- Reset the WHITE BALANCE set values.
--- Reset the GAMMA set value.
--- Restore the setter settings backed up in procedure 1) as needed.
7) Write the serial number.
→ Refer to “5-2. SERIAL NUMBER SETTING FUNCTION”
→ Refer to “11. SERIAL NUMBER WRITING PROCEDURES”
8) Reset system log information.
→ Refer to “5-4 SYSTEM LOG AND TEMPERATURE LOG INITIALIZATION”
→ Refer to “14-8. OTHER FUNCTIONS”
1-3. LCD MODULE REPLACEMENT PROCEDURES
1) Set “0” to USAGE TIME and perform initialization.
