Before Repair This equipment (SH-DV290), which is the component of the system, is supplied with power from the amplifier (SA-DV290).When repairing this equipment or checking operation of the system, be sure to connect the amplifier with it. Power supply and operation check in the state of it as a single equipmenet are impracticable. 2. Operating Instructions 3. Operation Checks and Component Replacement Procedures - This section describes procedures for checking the operation of the major printed circuit boards and replacing the main components. - For reassembly after operation checks or replacement, reverse the respective procedures. Special reassembly procedures are described only when required. 3.1. Checking for the FL P.C.B. 3 - Check the FL P.C.B. as shown below. 3.2. Checking for the main P.C.B. - Follow the (Step 1) - (Step 3) of item 3.1. 4 - Check the main P.C.B. as shown below. 5 4. Wiring Connection Diagram 5. Block Diagram 6. To Supply Power Source This unit is designed to operate on power supplied from system connected. When a component requires service, use the system connections to supply power source. For system connections. (Refer to Fig. 1) Fig. 1 7. Schematic Diagram Notes 7.1. Type Illustrations of ICs, Transistors and Diodes 7.2. Schematic Diagram Notes - This schematic diagram may be modified at any time with development of new technology. Notes: 6 - S601: Display mode (DISPLAY MODE) switch. - S602: DOLBY PRO LOGIC ( PRO LOGIC, OFF/ ON) switch. - S603: Super surround (SUPER SURROUND) switch . - S604: Super sound EQ (SUPER SOUND EQ) switch . - S605: Center focus (CENTER FOCUS) switch. - S606: Virtual rear surround (VIRTUAL REAR SURROUND) switch. - S607: Multi rear surround (MULTI REAR SURROUND) switch. - S608: Jog control () switch. - S609: Jog control () switch. - S610: Jog control () switch. - S611: Jog control () switch. - S612: Super 3D AI EQ (SUPER 3D AI EQ) switch. - S613: Seat position (SEAT POSITION) switch. - S614: Joystick (MULTI JOG) switch. - Indicated voltage values are the standard values for the unit measured by the DC electronic circuit tester (high-impedance) with the chassis taken as standard. Therefore, there may exist some errors in the voltage values, depending on the internalimpedanceof the DC circuit tester. / No mark: Power on Important safety notice: Components identified by mark have special characteristics impotant for safety. Furthermore, special parts which have purpose of fire-retardant (resistors), high-quality sound (capacitors), low-noise (resistors), etc. are used. When replacing any of components, be sure to use only manufactures specified parts showninthe parts list. Caution! - IC and LSI are sensitive to static electricity. - Secondary trouble can be prevented by taking care during repair. - Cover the parts boxes made of plastics with aluminum foil. - Ground the soldering iron. - Put a conductive mat on the work table. - Do not touch the legs of IC or LSI with the fingers directly.
