Page 60 Fig 1 GENERAL INFORMATION: The DP-3X deflection circuit differs from analog Hitachi projection televisions. It utilizes in a sense, two hori- zontal output circuits. One for Deflection and one for High Voltage. This allows for better deflection stabilization and is not influenced by fluctuations of the High Voltage circuit which may cause unacceptable breathing and side pulling of the deflection.

Page 71 DP-3X DIGITAL CONVERGENCE INTERFACE CIRCUIT EXPLANATION See Digital Convergence Interconnection Circuit Diagram for details. The Digital Convergence circuit is responsible for maintaining proper convergence of all three colors being pro- duced by the CRTs. Many different abnormalities can be quickly corrected by running Magic Focus. The Digital convergence Interconnect Diagram depicts how the Digital Convergence Circuit is interfaced with the rest of the Projection’s circuits.
Page 72 DP-3X DIGITAL CONVERGENCE INTERFACE CIRCUIT EXPLANATION data represents a specific correction signal for that specific location. When the Service Technician makes any adjustment, the new information must be stored in memory, EEPROM. The EEPROM only stores the 117 differ- ent adjustment points data, the SRAM interpolates to come up the additional 139 adjustment points for a total of 256 per color.
Page 73 DP-3X DIGITAL CONVERGENCE INTERFACE CIRCUIT EXPLANATION EXPLANATION OF THE DIGITAL CONVERGENCE INTERCONNECT DIAGRAM: INFRARED RECEIVER: During normal operations, the IR receiver directs it signal to the Main Microprocessor where it interprets the in- coming signal and performs a predefined set of operations. However, when the Service Only Switch is pressed, the Main Microprocessor ignores remote control commands.
Page 74 DP-3X DIGITAL CONVERGENCE INTERFACE CIRCUIT EXPLANATION MICROPROCESSOR: The Microprocessor is only involved in the Digital Convergence circuit related to disabling IR (Infrared Remote Control Signals). When the DCU is put into the Digital Convergence Adjustment Mode (DCAM) or Magic Fo- cus, the Microprocessor ignores IR pulses.
