[Adjustment of ballast unit output power (lamp power)]
1. List of parts requiring adjustment
When replacing the following parts, adjust the ballast unit output power (lamp power).
2. Adjustment jigs
The following jigs are required for adjusting the ballast unit output power (lamp power).
3. Ballast unit output power (lamp power) adjustment method
Adjust the ballast unit output power (lamp power) in the following 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.
