1. 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.

- 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 manufacture’s 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.
