Before RepairThis 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 Instructions3. 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.54. Wiring Connection Diagram5. Block Diagram6. To Supply Power SourceThis 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.

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.Voltage and signal line7: Positive voltage line: CD Playback signal line: Negative voltage line8.
