Page 3: Service Adjustments
SERVICE ADJUSTMENTS GENERAL This set has an On-screen Service Menu system included in the CPU that allows remote operation for most of the service adjustments. IC802 (EEPROM) REPLACEMENT When IC802 (EEPROM) is replaced, IC801 (CPU) will automatically write the initial reference data into IC802 for basic TV operation. However, the bus data should be checked and some bus data should be set up before attempting the service adjustments. - Page 4 Table 1. ON-SCREEN SERVICE MENU When IC802 (EEPROM) is replaced, check the bus data to confirm they are the same as below. The shaded menu should be checked and be set up or readjusted according to the procedures described in the following pages. Initial Setup Data marked with an * should be changed from Initial Reference Data.
- Page 5 Table 1. ON-SCREEN SERVICE MENU (Continued) When IC802 (EEPROM) is replaced, check the bus data to confirm they are the same as below. The shaded menu should be checked and be set up or readjusted according to the procedures described in the following pages. Initial Setup Data marked with an * should be changed from Initial Reference Data.
