Data Transfer
Service Data is duplicated and stored in separate EEPROMs in two locations.

PWB-MAIN - Working Service Data for TV operation

OPTICAL ENGINE - Backup Service Data
The Optical Engine also includes data for the Index Delay setting for color wheel timing determined at the factory.
The PWB-MAIN also includes User and/or ISF settings. The User/ISF data is not backed up on the Engine. However if used, it can
be backed up onto a USB flash drive.
Data Transfer Procedures should be followed...

After PWB-MAIN Replacement:
1. Restore Engine Data From Backup.
2. Restore Geometry Data From Backup.
3. Restore ISF Settings From Flash Drive . (Only if backup USB flash drive is available).

After OPTICAL ENGINE Replacement:
1. Restore Index Delay.
2. Save Engine and Geometry Setting to Backup (After performing any necessary H&V Position and
Geometry Adjustments).

Data Transfer Procedure:

1. Enter the Service Mode <MENU><2-4-5-7> Select the Data Transfer & Geometry Menu <0>
Data Transfer & Geometry Menu <MENU><2-4-5-7><0>
RESTORE ENGINE DATA FROM BACKUP
RESTORE GEOMETRY DATA FROM BACKUP
MANUAL GEOMETRY ALIGNMENT
RESTORE INDEX DELAY
SAVE ENGINE AND GEOMETRY SETTING TO BACKUP
BACKUP AND RESTORE ISF SETTINGS
RED ONLY AND GREEN ONLY
Warning: Only use "SAVE ENGINE AND GEOMETRY SETTING TO BACKUP"
after Optical Engine Replacement.
Note: Besides MANUAL GEOMETRY ALIGNMENT, six data transfer choices are listed on screen.

RESTORE ENGINE DATA FROM BACKUP - copies backup factory adjustments HVPOS, White Balance
and Index Delay from the Optical Engine to the PWB-MAIN.

RESTORE GEOMETRY DATA FROM BACKUP - copies backup factory Geometry Alignment data from
the Optical Engine to the PWB-MAIN.

RESTORE INDEX DELAY - copies factory Index Delay Adjustment data from the Optical Engine to the
PWB-MAIN.

SAVE ENGINE AND GEOMETRY SETTING TO BACKUP - copies all working data from the PWB-MAIN
into backup memory on the Optical Engine.

BACKUP AND RESTORE ISF SETTINGS - allows the ISF (ADV) video settings to be backed up and
restored using an external USB flash drive.

RED ONLY AND GREEN ONLY - displays the video in red or green only during ISF Calibration.
