* Writing a software program (before main PWB is mounted)

Use the DLP Composer Lite Ver. 4.2 or higher to download the firmware.

After writing the specified version of firmware to the PWB using the RS232C cable, check the version of the written firmware.

If no software program is written, all three LEDs light up in the chassis inspection process.

1. Calling and quitting the process mode with the control keys on this model.

* Although it is possible for the process OUT to exit using the process menu, the IN/OUT toggle command is also available considering the existing specification. 1-1. Calling and quitting

With the menu not displayed, press the "ENTER", "ENTER", "VOL+", "VOL-", "ENTER", "ENTER" and "MENU" keys on the remote control (one for C50/45 or P25/20 system is also usable) or on the main unit.

1-2. Others

Press the S2551 process key (toggle) on the main PWB to call and quit the process menu. Note: When adjusting in the process mode, set a signal with a vertical frequency of 60 Hz or no signal. (May not be properly adjusted with other signals.)

2. Resetting the lamp timer for this model

2-1. Resetting procedure

In Stand-by, run this command to clear the operating time of the lamp to 0 and turn on the power. Press and hold "▼", "ENTER", and "MENU", and then press the "STANDBY/ON" key of the set.

3. Forced disabling of the System-Lock of this model

3-1. Disabling procedure

With System-Lock input window onscreen, press the "MENU", "ENTER", "ENTER", "MENU", "ENTER", "ENTER" and "MENU" keys, in this order, on the remote controller.

3. Ballast unit output power (lamp power) adjustment method Adjust the ballast unit output power (lamp power) in the following method.

[Setting method]

[Adjustment method]

(1)Unplug the ballast unit lamp cable(QCNW-D573WJQZ) of the projector from the lamp and connect the cable to the connecting cord (QCNW-E007WJZZ).

(2) Connect the connecting cord (QCNW-E007WJZZ) to the adjustment jig (RUNTZA018WJZZ).

(3) Connect TP1 of the adjustment jig (RUNTZA018WJZZ) to the negative terminal of the tester and TP2 to the positive terminal.

(4) Turn on the projector.

(5) Age the projector for 60 seconds or more.

(6) Adjust the volume resistor (R7728) of the ballast control PWB (DUNTKD148WEF0) so that the voltage of the tester reaches 83± 0.5 V.

Adjustment value: 83± 0.5 V

[Cautions]

(1) Caution for electric shock: Do not touch the test points TP1 and TP2 of the adjustment jig when supplying power since a high voltage and large current is applied to them.

(2) Caution for heat: Be careful that the resistance load of the adjustment jig produces a high temperature when supplying power.

(3) Connection of the lamp cable: Check that the lamp cable and connecting cord (QCNW-E 007WJZZ) are connected securely.

Poor connection may cause smoking or ignition due to arc discharge.

TROUBLE SHOOTING TABLE

Schematic Arc Discharge

Is R766 in the OPEN status?

Is LAMP-EN/SYNC signal properly sent to pin (14) of the connector P704? (Refer to the waveform chart ©.)

Check the main PWB.

Check circuits R766 and after or replace R766.

Are GATE waveforms of Q901 and Q903 appropriate? (See waveform diagram ®.)

Check the ballast PWB.
