7.1.3 AUTOMATIC BACKUP OF DIGITAL VIDEO ASSY DATA
Description
Flow of basic automatic backup
Auto copies data of EEPROM (IC1204/2k bit) on the DIGITAL VIDEO Assy as data for backup in the Assy replacement to one part of
EEPROM (IC5502/64k bit) of the RGB Assy (area A of figure below).
Therefore DIGITAL VIDEO Assy or main unit adjustment item in the RGB Assy replacement (data of EEPROM on DIGITAL VIDEO
Assy) is succeeded to Assy after replacement.
Note :
COLOR and TINT are main unit adjustment items, but does not automatic backup because there are data in area C
(refer to figure below).
Use a key word, and judge each data (area A and B) whether it is the adjusted data or the not adjusted data, and perform the copy operation.
