Error code Error message Description Solution
4 GPSU(12V) Fail Power supply is abnormal. Confirm that 12 Vdc is output from #1, 2, 3 pins of
the Power Supply cable (6-pin) supplied from the top
face of the Power Module to the MOTHER PWB. If
not confirmed, replace the Power Module. (Refer to
the Start-up failure page.)
5 Lamp Unlit Lamp doesn’t light up. Check the J17 and J18 cable of the Slave uC PWB.
12 E2PROM R Fail E2PROM data read error is detected. Check the respective boards (cables) of the CPU
and KEYPAD.
15 E2PROM W Fail E2PROM data write error is detected. Check the respective boards (cables) of the CPU
and KEYPAD.
120 DLP Ack Fail ICP failed operation. It could be caused by configuration
files lost, disk space issue, or DISKCHIP corruption issue. ICP, CPU, ROUTER, LAN cable
Check the following and correct them ifany error is
discovered.
1
Check version info to examine whether the
firmware and data of the CPU PWB has been
written correctly.
Rewrite it if it is written wrong.
2
Check version info to examine whether the
firmware and data of the ICP board has been
written correctly.
Rewrite it if it is written wrong.
3
Confirmation of PWB mounting conditions
1) Is the CPU PWB correctly mounted on the
MOTHER PWB?
2) Is the ICP PWB correctly mounted on
theMOTHER PWB?
After confirming the above mentioned conditions,
turn the power supply ON. If thereis still an error,
replace the ICP and CPU PWBs in this order. If the
error disappears, then thereplaced PWB is found to
be faulty.
121 Lens Fail Lens unit control error Check the MOTHER PWB.
140 DLP CommR Fail No communication with the ICP board.
(Communication I/F is RS-232C) Confirm that the RS-232 I/F between CPU and ICP
is normally started (The status of front LED).
141 DLP CommE Fail No communication with the ICP board and DCC.
(Communication I/F is Ethernet) Confirm that the Ethernet I/F between CPU and ICP
is normally started (The status of front LED).
151 Fan1 Stop Fan1 has stopped. Check the corresponding FAN (referring to the
layout), cable, and Fan Drive board.
152 Fan2 Stop Fan2 has stopped.
153 Fan3 Stop Fan3 has stopped.
154 Fan4 Stop Fan4 has stopped.
155 Fan5 Stop Fan5 has stopped.
156 Fan6 Stop Fan6 has stopped.
157 Fan7 Stop Fan7 has stopped.
158 Fan8 Stop Fan8 has stopped.
159 Fan9 Stop Fan9 has stopped.
164 ICP Fan Stop ICP Fan has stopped. Check the CPU board and the fan of the sameboard.
165 GPI MACRO(n) Selection Invalid Selection of preset button (n) through GPI is invalid because
metadata is enabled. Indicates control prohibitions status (command).
166 GPI Control Invalid Projector control through GPI is invalid because projector is
busy. Indicates control prohibitions status (command).
177 Tamper Fail Service door tamper switch of projector is open. Examine the fixing method for the relatedinstallations.
Check the J28, J29, J30 cables of the Slave uC PWB
178 Marriage Tamper Fail Marriage tamper switch of projector is open. Check the fitting conditions of the ICP/NC-80LB with
the MOTHER board, and ENIGMA boards provided
on the NC-80LB.
Check the NC-80LB front cover mounting, the MOTHER
PWB, TAMPER board, Tamper Switches, and cables.
180 CPU Fail(Mem) System Test Failed during lamp on. (Memory) Check the CPU board.
201 Error Log Write Fail Failed to write error log. Check the CPU board.
215 Filter Time Over The time to exchange filters. Filter cumulative time exceeded.
220 Fan Exchange Time The time to exchange fans Fan cumulative time exceeded.
230 Router Fail Failed to control router. Check the router (including power supply), LANcables,
and the CPU.
232 MAC Write Fail Failed to setup MAC address of CPU board. Check the CPU board.
235 Router Self Check Fail Router health-check error. Confirm to the separate sheet of troubleshooting.
(Router Trouble Shooting LDD0017 rev*.*.pdf)
240 SIB Comm Fail Failed to communicate with SIB. Check the LAN cable.
Check the fitting conditions of the NC-80LB/DS
board (IC1600,IC1604) with the MOTHER board.
After confirming the above mentioned conditions,
turn the power supply ON and examine the error-
related status.
If there is still an error, replace the NC-80LB/DS and
check the error-related status.
241 SIB Error SIB internal error. Check the NC-80LB/DS
242 SIB FPGA Reboot Executed to re-boot SIB FPGA for recovery. Indicates SIB FPGA Status.
245 Fan10 Stop Fan10 has stopped. Check the corresponding FAN (referring to the
layout), cable, and Fan Drive board.
246 Fan 11 Stop Fan11 has stopped.
247 Fan 12 Stop Fan12 has stopped.
248 Fan 13 Stop Fan13 has stopped.
249 Fan 14 Stop Fan14 has stopped.
