Depending on the parts replaced during serving, it will be necessary to perform corrections of the "fan rotation
control circuit" and "filter clog sensor circuit". Please ensure that all service staff are familiar with the necessary
steps.
Corrections will be necessary under the following conditions.
*When TACH IC (IC1092) is replaced.
*When EEPROM (IC1017) is replaced.
*Circuit board A is replaced.
*Filter clog sensor (CF2002) is replaced.
Preparation
*PC with communication cable (Serial cable with D-sub 9 pin terminals).
*Service software Ver1.00 or higher.
Please download the service software from the projector service homepage website.

Sequence of Procedure to carry out the correction tasks.
Procedure for fan rotation correction
1. Switch the projector to "Stand-by" mode (POWER indicator is in red).
2. Connect the serial terminals on the projector and the PC by using a communication cable.
3. Start up the service software(ServiceLB80E.exe) on the PC, click the "Adjustment" tab.
4. Click "Tach Ic Revision" to set the correction value.
*Only when TACH-IC(IC1092) or EEPROM(IC1017) has been
replaced, click "Tach Ic Revision" otherwise do not click it.
When "Tach Ic Revision" is clicked, it will be under guarantee
specially temperature effect.
5. Click "Exit" to complete the correction.
Procedure for sensor correction (Approx. 15 minutes to complete)
1. Clean the intake air filter completely before starting the steps.
(If the filter is dirty and clogged, the correction may not be completed properly.)
*If the filter is too dirty to clean, replace it with a new one.
2. Correct the serial terminals on the projector and the PC by using a communication cable.
3. Press the POWER button of the projector. Power indicator lights.(It is not necessary to enter the input signals.)
*If the "Auto-signal search" is working, it must be turned OFF by using the control buttons.
4. Start up the service software(ServiceLB80E.exe) on the PC, click the "Adjustment" tab.
5. Click "FLTR Sensor" to start the filter clog correction.
(If the correction does not start automatically, tuen OFF the projector, disconnect/connect the power cable and
restart it to repeat the steps.)
"Sensor correction" window
*While the correction is in progress, the window is
magenta (for approx. 15 min).
*While the correction is in progress, do not exit from
the adjustment software or from the PC.
Do not turn off the POWER of the projector.
Don't turn power off during revising it will be not effect.
6. In approx. 15 minutes, the "Sensor correction" window closes automatically.
This completes the correction.
Click "Exit" to complete the correction steps.
