jedyne do czego mogę mieć zastrzeżenie to jakość zdjęć zawartych w przesłanej instrukcji serwisowej ponieważ są fatalnej jakości, praktycznie nieczytelne. tak poza tym jestem zadowolony to jest to czego szukałem.
Instrukcja jest OK. Schematy czytelne, opisane niektóre procedury.

Actual automatic backup operation
1. When the DIGITAL VIDEO Assy is replaced (Using the service Assy) Keyword modification is not needed. Replace the DIGITAL VIDEO Assy with that for service, then turn on the power. Thus, the backup data in the EEPROM of the RGB Assy are automatically copied to the EEPROM of the DIGITAL VIDEO Assy.

2. When the RGB Assy is replaced (whether replaced with the assembly for service or not does not matter) Replace the RGB Assy, then enter the Service Factory mode. The backup data in the EEPROM of the DIGITAL VIDEO Assy are then automatically copied to the EEPROM of the RGB Assy.

3. When the DIGITAL VIDEO Assy is replaced (reuse of a repaired part) When installing the repaired DIGITAL VIDEO Assy in other unit It is necessary to change the keyword of the DIGITAL VIDEO Assy to be reused to "not adjusted." Before removing the DIGITAL VIDEO Assy to be reused, enter the Service Factory mode and execute SERVICE PARTS in the INITIALIZE item. (The unit must operate properly, and OSD display must be possible.) If SERVICE PARTS cannot be executed, readjustment is required. Note: If a repaired DIGITAL VIDEO Assy is mounted in another unit (Unit 2) without this change of keyword, the automatic backup function will not work properly. Moreover, if Unit 2 is set to Service Factory mode in this condition, data in force before the repair of the DIGITAL VIDEO Assy will be copied to Area A of the RGB Assy of Unit 2, overwriting the data necessary for Unit 2. Once overwritten, the original data will not be restored. 4. When the DIGITAL VIDEO Assy is replaced (reuse of a repaired part) When installing the repaired DIGITAL VIDEO Assy in the original unit It is not necessary to change the keyword. After the repaired DIGITAL VIDEO Assy is mounted in the original unit, the unit can operate with its latest adjustment values. After replacement, turn on the power. Then, the backup data in the EEPROM of the RGB Assy will automatically be copied to the EEPROM of the DIGITAL VIDEO Assy.

5. When replacing both the DIGITAL VIDEO Assy and the RGB Assy simultaneously Automatic backup function does not work properly. Readjustment is necessary.
Others
1. As for the COLOR and TINT items, even though they are adjustment data for the unit, as they are stored in Area C, they are not automatically backed up. For these two items, the following applies: 1 When only the DIGITAL VIDEO Assy is replaced Readjustment is not required, as data are stored in the RGB Assy. 2 When the RGB Assy is replaced After repair, readjustment is required. 2. Except for data for the COLOR and TINT items, data in Area C in the EEPROM of the RGB Assy are assembly-adjustment data. Readjustment is not required when the RGB Assy is replaced with one for service.
